# Neuro Exam Essentials Only what your instructor said to know: lectures, live class, slides, and the assigned book pages (with the "do not read" parts left out). Read in book = a part your instructor told you to read in the textbook. How to use this ## One tab. One chunk. Then flip cards. - Read the colored 60-second box first. That's the big idea. - Open one chunk at a time. Close it when done (it'll say ✓ seen). - Do the tap-to-flip cards, then the quiz. - Hit Mark done at the bottom. Take a break between tabs. Your instructor's study advice: the nursing care overlaps across all these diseases. Eye problem → protect the eye. Can't swallow → nutrition support (weights, calorie counts, prealbumin). Weak or stiff → mobility and fall prevention. Don't memorize slide by slide. Understand the idea. But do notice how brain, spinal cord, and peripheral nerve problems look different. The nervous system map Think of a house. The brain is the electrical panel. The spinal cord is the main cable running down the wall. Peripheral nerves are the wires going out to every room. | Central (CNS) | Peripheral (PNS) | | --- | --- | | Brain + spinal cord | Spinal nerves (from the spine) · 12 cranial nerves (from the brain) · autonomic system | Autonomic system = automatic, not under your control: - Sympathetic = "fight or flight." Speeds things up (heart rate, breathing). - Parasympathetic = "rest and digest." Slows things down. Word bank (terms that show up everywhere) | Word | Plain meaning | | --- | --- | | intracranial pressure (ICP) | Intracranial pressure: pressure inside the skull | | level of consciousness (LOC) | Level of consciousness: how awake and aware | | Glasgow Coma Scale (GCS) | Glasgow Coma Scale: scores LOC from 3 (no response) to 15 (normal) | | Aura | A warning sign right before a migraine or seizure | | Dysphagia | Trouble swallowing → aspiration risk | | Dysarthria | Trouble speaking clearly (slurred) | | Diplopia | Double vision | | Nystagmus | Eyes jerk side to side on their own | | Ptosis | Drooping eyelid | | Photophobia / phonophobia | Light hurts / sound hurts | | Paresthesia | Numbness or tingling | | Acetylcholine (ACh) | The "go" chemical that makes muscles move | | Dopamine | The "brake" chemical that smooths movement (also pleasure) | Your instructor's 15 neuro terms have their own tab: Terms. Review class: exam breakdown + how to study Review class From the in-class exam review (Joline case study + NCLEX questions). | Exam section | Points | | --- | --- | | Peripheral nervous system (PNS) | 28 | | Trauma: stroke, head injury, intracranial pressure (ICP) | 32 | | Renal: acute and chronic kidney disease (lecture recordings) | 18 | | Michelle's content (use her posted study guide) | 10 | | Total | 90 · about 1 hr 35 min. Don't rush. | - You only need what she did not cross off in the book + what's in the lecture recordings and PowerPoint. Some lecture content isn't in the book. That's okay, it still counts. - Use the outline in the syllabus as quiz questions. - Studying alone? Record yourself answering out loud on your phone, then play it back next to your notes. Saying it out loud moves it to long-term memory. - On her big day-one med chart, write only the "exception to the rule" facts. Those are what get tested. - Stuck? Email her instead of going down a YouTube rabbit hole. Quick recall · tap to flip The 60-second version ## 15 words. Break them into pieces and they explain themselves. - a- = without · dys- = hard or bad · hemi- = half (one side) - -plegia = paralyzed (can't move) · -paresis = weak (can move a little) - -phasia = speech/language · -lexia = reading · -graphia = writing - -opia / -opsia = vision · gnosia = knowing/recognizing · praxia = doing From your instructor's "Neurology – Medical Terminology" list Talking, reading & writing (4) ### 1. Aphasia Word parts: a- (without) + phasia (speech) Means: trouble with language. The brain can't make or understand words. The brain's dictionary is broken. The mouth works fine; the words don't come out right, or what you hear makes no sense. Example: a stroke patient wants water but says "chair," or can't understand "squeeze my hand." 3 types: Expressive (Broca) = understands, can't speak · Receptive (Wernicke) = can't understand · Global (mixed) = both. ### 2. Dysarthria Word parts: dys- (hard) + arthr (joint/articulate) Means: slurred speech because the mouth, tongue, or face muscles are weak. The words are right, but the mouth is clumsy, like talking after a dentist numbs you. Example: the patient knows exactly what to say, but it sounds mumbled. Don't mix up: Aphasia = a word problem (brain's language center). Dysarthria = a muscle problem (words are right, just slurred). ### 3. Alexia Word parts: a- (without) + lexia (reading) Means: can't read, even though they could before and their eyes work. Example: the patient looks at a menu but the letters mean nothing. ### 5. Agraphia Word parts: a- (without) + graphia (writing) Means: can't write, even though the hand can hold the pen. Example: asked to sign a consent form, they can't form the letters of their name. Eyes & vision (4) ### 4. Papilledema (choked disc) Word parts: papilla (optic disc) + edema (swelling) Means: the optic disc (where the eye nerve connects, at the back of the eye) is swollen. The provider sees it with an ophthalmoscope. Pressure in the skull pushes on the eye nerve and "chokes" it, like a garden hose swelling when the water can't get out. Key point: papilledema = always a sign of ↑intracranial pressure (ICP). ### 9. Nystagmus Means: the eyes jerk or bounce side to side (or up and down) on their own. Like the eyes are watching a fast tennis match that isn't there. Seen in: multiple sclerosis (MS), meningitis, stroke, brainstem problems. ### 12. Ptosis Means: a drooping upper eyelid. Ptosis sounds like "toe-sis": the lid falls down toward your toes. Seen in: myasthenia gravis, uncal herniation (CN III), stroke. ### 13. Diplopia Word parts: dipl (double) + opia (vision) Means: double vision. Sees two of everything. Nursing: eye patch, switched between eyes every few hours. ### 14. Homonymous hemianopsia Word parts: homonymous (same) + hemi (half) + an (without) + opsia (vision) Means: blind in the same half of the vision field in both eyes. For example, they can't see anything to their left. Like someone put tape over the left half of both lenses of their glasses. Nursing: teach to turn the head side to side (scan). Put food and items on the side they can see. They may eat only half the plate. Movement & coordination (5) ### 7. Hemiparesis Word parts: hemi (half/one side) + paresis (weakness) Means: weakness on one side of the body. They can still move it, just not strongly. Example: weak right hand grip and right leg after a left-brain stroke. ### 15. Hemiplegia Word parts: hemi (one side) + plegia (paralysis) Means: paralysis on one side of the body. Can't move it at all. Memory trick: Paresis = Partial (weak). Plegia = Paralyzed (can't move). Both are on the side opposite the brain injury. ### 8. Apraxia Word parts: a- (without) + praxia (doing/action) Means: can't do learned, planned movements, even though the muscles are strong and they understand the request. The muscles work, but the brain lost the "instructions" for the task. Example: handed a toothbrush, they don't know the steps to brush their teeth. Nursing: simple, short, one-step directions; be patient. ### 10. Ataxia Word parts: a- (without) + taxia (order/coordination) Means: poor coordination and balance. Wobbly, unsteady walking; clumsy movements. Walking like you're on a moving boat. Nursing: fall precautions. ### 6. Proprioception Means: your body's sense of where its parts are without looking (body position sense). It's how you can touch your nose with your eyes closed. If lost: the patient doesn't know where their arm or foot is → falls, injuries. Watch the affected limb. Recognizing things (1) ### 11. Agnosia Word parts: a- (without) + gnosia (knowing) Means: can't recognize familiar objects, people, or sounds, even though their senses work. The eyes see a fork, but the brain can't name it or tell what it's for. Nursing: safety. They might misuse objects. The "A" trio: Apraxia = can't do (action) · Agnosia = can't know (recognize) · Ataxia = can't coordinate (wobbly). All 15 at a glance | # | Term | Simple meaning | | --- | --- | --- | | 1 | Aphasia | Trouble with language (words) | | 2 | Dysarthria | Slurred speech (weak mouth muscles) | | 3 | Alexia | Can't read | | 4 | Papilledema | Swollen optic disc = ↑intracranial pressure (ICP) | | 5 | Agraphia | Can't write | | 6 | Proprioception | Sense of where your body is | | 7 | Hemiparesis | One-sided weakness | | 8 | Apraxia | Can't do learned movements | | 9 | Nystagmus | Jerky, bouncing eyes | | 10 | Ataxia | Poor coordination/balance | | 11 | Agnosia | Can't recognize things | | 12 | Ptosis | Droopy eyelid | | 13 | Diplopia | Double vision | | 14 | Homonymous hemianopsia | Blind in the same half of both eyes | | 15 | Hemiplegia | One-sided paralysis | Flashcards · tap to flip Practice A client clearly says "I want my glasses," but the words are mumbled and hard to understand. This is: The right words, but slurred = a muscle problem = dysarthria. Practice A client eats only the food on the right side of the plate. The nurse suspects: They can't see the left half of their field. Teach head scanning; turn the plate. Practice A client holds a comb but can't figure out how to use it, even though the arm is strong. This is: Strong muscles, lost "how-to" for a learned task = apraxia. Practice The provider documents papilledema. The nurse knows this means: A swollen optic disc is always a sign of ↑ICP. Practice A client after a stroke can lift the right arm a little but it's weak. Correct term? Paresis = partial (weak). Plegia = paralyzed. Practice A client walks with a wide, wobbly gait and loses balance. Priority nursing action? Ataxia = poor coordination → fall risk. The 60-second version ## Stroke = a "brain attack." Time is brain. - transient ischemic attack (TIA) = mini warning stroke; symptoms gone in 30–60 min. Prevent the real one. - \~90% are ischemic (clot). The rest are hemorrhagic (bleed). - computed tomography (CT) head WITHOUT contrast first, to rule out a bleed. - tissue plasminogen activator (tPA) (alteplase) within 3 to 4.5 hrs of when symptoms started, only for ischemic. - First sign of trouble (↑intracranial pressure (ICP)) = change in mental status. A stroke is a heart attack of the brain. Ischemic = a clogged pipe (no blood gets through). Hemorrhagic = a burst pipe (blood leaks where it shouldn't). The treatment for one is dangerous for the other, which is why the computed tomography (CT) comes first. transient ischemic attack (TIA): the warning sign - Brief drop in blood flow to the brain → temporary stroke-like symptoms. - Usually gone in 30–60 minutes, often before reaching the emergency room (ER). Many people never go. - Symptoms are one-sided: numbness or weakness of face/arm, blurred or double vision, slurred speech, trouble swallowing. - It's a red flag: high risk of an ischemic stroke soon. Prevention is the key intervention: - #1 risk factor = hypertension. Control blood pressure (BP). - Diabetes: keep glucose in range. Exercise, healthy food. - Antiplatelets: aspirin and clopidogrel. Both together = dual antiplatelet therapy (same as after a myocardial infarction (MI)). Don't mix up the classes: Antiplatelets = aspirin, clopidogrel (stop platelets sticking). Anticoagulants = heparin, warfarin, direct oral anticoagulants (DOACs) like apixaban, rivaroxaban, dabigatran. Ischemic vs. hemorrhagic Blood flow cut off for more than a few minutes → brain cells starve of oxygen → brain infarction (like a myocardial infarction (MI), but in the brain). | Type | Cause | Onset | | --- | --- | --- | | Thrombotic (ischemic) | Clot builds slowly from atherosclerosis, often where arteries split (carotids, circle of Willis) | Slow/gradual: symptoms come and go, or slowly worsen. Body grows collateral circulation. | | Embolic (ischemic) | Clot travels, usually from the left side of the heart. Big risk: A-fib, valve disease | Sudden; often improves quickly too | | Hemorrhagic | Vessel breaks: severe hypertension (HTN) (incl. cocaine), ruptured aneurysm, or an ischemic stroke that turned into a bleed | Sudden or slow (depends on the bleed) | Right-heart clot → lungs (PE). Left-heart clot → brain (stroke). Left vs. right brain stroke The brain controls the opposite side of the body. Left brain stroke → right side weak. Right brain stroke → left side weak. | Left hemisphere (dominant) | Right hemisphere | | --- | --- | | Language, math, analytical thinking | Visual and spatial awareness | | Trouble understanding and using language (aphasia) | Unilateral neglect: ignores the left side of the body | | Slow, cautious; anxious with new tasks | Impulsive, poor judgment, unaware of deficits, denial | | Depressed, guilty, quickly angry and frustrated (they know something's wrong) | Memory loss, disoriented | | Right-side weakness | Left-side weakness · top priority: risk for injury | Brain-area map slide: your instructor said do not memorize it. BE FAST: teach the public BBalance: loss of balance or coordination, dizzy EEyes: blurred or double vision FFace: smile. One side drooping? AArms: raise both. One weak or drifting down? SSpeech: repeat "You can't teach an old dog new tricks." Slurred? Garbled? TTime: call 911 right away. Note the exact time symptoms started. Why call 911 instead of driving? The ambulance calls ahead: computed tomography (CT) room ready, stroke scale started, tissue plasminogen activator (tPA) prepared, oxygen and glucose checked. In the emergency room (ER): assessment & computed tomography (CT) - Priority = get them to a stroke center. Not the time for a full head-to-toe. - airway, breathing, circulation (ABCs) first, then a rapid neuro (stroke) assessment. - National Institutes of Health (NIH) Stroke Scale: trained, certified staff; checks level of consciousness (LOC), movement, feeling, speech, understanding. Broader than BE FAST. Don't memorize its parts; just know it's a valid, reliable, evidence-based tool for consistent tracking. CT of the head WITHOUT contrast (or magnetic resonance imaging (MRI)) is one of the first tests. Why no contrast? Contrast would look like a bleed. CT shows a hemorrhage, sets a baseline, rules out tumors. An ischemic stroke often doesn't show for 24 hrs, so a negative CT doesn't rule it out. tissue plasminogen activator (tPA) (alteplase): clot buster - For ischemic only. Never for hemorrhagic. - Must start within 3 hours of symptom onset (often extended to 4.5 hrs). Counted from when symptoms started at home, not emergency room (ER) arrival. You don't need the extension criteria. - Not everyone qualifies: check bleeding risk. Before you hang tPA: make sure the head computed tomography (CT) is done and shows no bleed. Not ordered? Get it ordered. - Big risk = bleeding → bleeding precautions. - Keep blood pressure (BP) controlled so ischemic doesn't turn hemorrhagic. - Repeat CT after the infusion to check for a new bleed. Other procedures (know the name and idea only): - Intra-arterial thrombolysis: tPA put directly into the clot; up to 6 hrs. - Endovascular thrombectomy: catheter pulls the clot out. - Prevent future strokes: angioplasty with stent (filter catches pieces) or carotid endarterectomy (neck incision to remove plaque). After any of these: check the site for bleeding, vital signs, neuro checks (new stroke from loose clots?), hoarseness and trouble swallowing (nerves in the neck, like the vagus), and cerebral hyperperfusion (a rush of blood into an area used to low flow → can bleed). Signs to assess - Cognition: restless, confused, memory, focus. level of consciousness (LOC) drop = late. - Motor: hand grips, push/pull feet. Equal both sides? - Flaccid paralysis = limp, can't beat gravity (e.g., foot drop). Spastic = constant contraction → contractures. - Sensory: touch, pain, numbness, neglect. - Eyes: pupils equal, round, reactive to light and accommodation (PERRLA) plus the whole visual field (lost side vision?). - Heart: usually hypertensive; murmur (clot on a valve?); rhythm (A-fib). - Psychosocial: personality and emotion changes. Nursing priorities (acute stroke) 1. Oxygen first. oxygen saturation (SpO₂) under 94%? Think: partial airway obstruction (tongue), hypoventilation, aspiration (most common). 2. intravenous (IV) (emergency meds; they may not swallow). 3. Cardiac monitor (A-fib). 4. nothing by mouth (NPO) until a swallow screen. The registered nurse (RN) does the bedside screen. Coughing, pocketing food, slurred speech → speech therapy consult. 5. Glucose under 140 (high sugar blocks reperfusion). 6. blood pressure (BP) slightly high to push blood to the brain. Book guideline ≤150 systolic, but follow the patient's own orders and baseline. 7. Watch for ↑intracranial pressure (ICP). Neuro checks every 15–30 min acutely; BP at least every 15 min. Never skip pupils. Patient declining 24 hrs after a stroke (more lethargic, vitals changed, sluggish pupils)? Call Rapid Response and the provider. Expect a computed tomography (CT). - Most likely complication = ↑ICP (→ seizures, respiratory failure, ↓level of consciousness (LOC)). - Don't take BP on the affected arm: inaccurate (less vascular tone). Aspirin & stroke core measures Why no aspirin right away (unlike a myocardial infarction (MI))? Could be a bleed, may be getting tissue plasminogen activator (tPA), may have dysphagia. Giving it early doesn't improve stroke outcomes. - Give aspirin 325 mg within 24–48 hrs after onset. - No aspirin within 24 hrs of tPA. Core measures (hospital must do + document to get paid): 1. tPA if they qualify (3–4.5 hrs). 2. venous thromboembolism (VTE) prevention: sequential compression devices (SCDs), enoxaparin/heparin, walking. 3. By end of day 2: antiplatelet or anticoagulant (A-fib/flutter → anticoagulant). Discharged on it. 4. Discharged on a statin (cholesterol med). 5. Stroke education documented (signs, 911, meds). 6. physical therapy (PT)/occupational therapy (OT) rehab assessment. Tests & swallow nerves (Mr. Stokes case) | Test | Why | | --- | --- | | Non-contrast computed tomography (CT) head | Rule out bleed, baseline, rule out tumor | | Cardiac monitor | A-fib (with rapid ventricular response (RVR)) | | Echocardiogram | Shows heart valves (clots?) and ejection fraction | | Carotid ultrasound | % of plaque blocking the carotids | | Swallow study | Diet texture (thickened liquids, pudding, no water) | The 2 cranial nerves you MUST know: cranial nerve (CN) IX (glossopharyngeal) and CN X (vagus), the swallowing nerves. They must be intact before the patient eats or drinks. "If you don't know, pick vagus." Delegation tip from class: licensed practical nurse (LPN) can give routine injections (like insulin). Hygiene → unlicensed assistive personnel (UAP). NCLEX wants you to use each person's role wisely. Hemorrhagic stroke treatment Goal: stop the bleeding and lower pressure on the brain. - Stop any meds that cause bleeding; may need blood products. - Anti-seizure meds (a seizure raises intracranial pressure (ICP)). - Bed rest and supportive care so the body can absorb the blood. Don't push them up to the chair. Surgery: - Aneurysm → coiling (coils fill the bulge) or clipping (clip at its base). - arteriovenous malformation (AVM) (arteriovenous malformation: tangled weak vessels, often in kids) → surgically removed.

Stroke types & risk (book)Read in book Brain can't store oxygen or glucose. Blood flow cut for a few minutes → infarction. "Brain attack" = treat like a myocardial infarction (MI). | | Thrombotic | Embolic | Hemorrhagic | | --- | --- | --- | --- | | Onset | Gradual; steps/worsening | Sudden | Sudden (gradual if from hypertension (HTN)) | | level of consciousness (LOC) | Awake | Awake | Deepening lethargy → coma | | Linked to | HTN, atherosclerosis; transient ischemic attack (TIA) first | Heart disease (A-fib) | HTN, vessel problems, genetics | | Headache | Slight | — | Severe; seizures common | | Recovery | Weeks–months | Usually rapid | Variable; often permanent deficits | - Intracerebral hemorrhage (ICH): bleeding into brain tissue, usually from severe HTN; cocaine can trigger it. - Subarachnoid hemorrhage (SAH): bleeding between pia and arachnoid, usually a ruptured aneurysm or arteriovenous malformation (AVM). Vasospasm (artery clamps down) afterward → more ischemia. - Leading causes: smoking, obesity, HTN, diabetes, high cholesterol. Also cocaine, heavy alcohol, birth control pills in at-risk women, family history. - 5th leading cause of death; #1 cause of long-term disability. "Stroke belt" = 8 southeastern states. - Prevent with the ABCS: Aspirin when appropriate, Blood pressure, Cholesterol, Smoking cessation. Assessment (book)Read in book - First priority: get to a stroke center. Assess within 10 minutes of arrival (ABCs, neuro). - History: exact time symptoms started, did they get better or worse, meds (anticoagulants), drug use. - Sudden drop in level of consciousness (LOC)? Rule out low blood sugar or low oxygen first. They look like a stroke but are easy to fix. - subarachnoid hemorrhage (SAH): "worst headache of my life," nausea/vomiting, photophobia, stiff neck. - Most important ongoing check = LOC (GCS or National Institutes of Health Stroke Scale (NIHSS)). - Impaired airway defense: weak cough + dysphagia → aspiration pneumonia. Screen swallowing. - Heart: murmur, A-fib, heart failure, endocarditis. - blood pressure (BP): often 180–200/110–120 on arrival. A somewhat high BP (about 150/100) keeps the brain perfused; higher can extend the stroke. - Psychosocial: body image, coping, money worries; screen for depression. Emotional lability = sudden laughing or crying for no reason (frontal lobe or right brain). Tell the family it's the stroke, not them. - Labs: no test confirms stroke. High Hgb/Hct = severe stroke; high white blood cell count (WBC) = infection or stress; glucose and hemoglobin A1C (A1C) check diabetes. NIHSS (Table 38.2): your instructor said don't memorize it, just be familiar. It scores 0 (normal) to 42 (worst) and helps decide who gets tissue plasminogen activator (tPA). tissue plasminogen activator (tPA) (alteplase) rules (book)Read in book - Explain to patient/family and get informed consent. - Door-to-needle goal: 45 minutes from emergency department (ED) arrival. - If blood pressure (BP) is too high, give a fast antihypertensive first. BP must be below 185/110 to start, and kept there. Box 38.4: care during and after alteplase - Admit to critical care or a stroke unit. Double-check the drug. - Give with a programmable pump over 60 min (10% as a 1-minute bolus). Never push it by hand. - Neuro checks + vitals: every 10–15 min during the infusion, then every 30 min for at least 6 hrs, then hourly for 24 hrs. - Use the same BP device each time (manual vs. automatic vs. arterial line readings differ). - BP ≥185/110 before tPA, or >180/105 after (first 24 hrs) → give antihypertensive as ordered, e.g., intravenous (IV) labetalol. - No invasive tubes (NG tube, Foley) until stable, usually 24 hrs (bleeding). - Stop the infusion and call for severe headache, sudden high BP, nausea/vomiting. - Follow-up computed tomography (CT)/magnetic resonance imaging (MRI) before starting anticoagulants or antiplatelets. Drug Alert: watch closely for bleeding: brain bleed (headache, level of consciousness (LOC) change) and any other site. Procedures & intracranial pressure (ICP) after stroke (book)Read in book - Endovascular: intraarterial tissue plasminogen activator (tPA) (within 6 hrs), mechanical embolectomy (pull clot out), carotid stent. - After a carotid stent, teach to report: severe headache, level of consciousness (LOC) change (drowsy), muscle weakness, severe neck pain, neck swelling, hoarseness or trouble swallowing (nerve damage). - Hemorrhagic from arteriovenous malformation (AVM)/aneurysm: procedure to stop bleeding. - ↑ICP risk is highest the first 72 hrs. Reassess every 1–4 hrs. Critical Rescue: the first sign of ↑ICP is a declining LOC. Report any decline to the provider or Rapid Response right away. Prevent ↑ICP: - head of bed (HOB) up per protocol. Head midline, neutral. - O₂ if oxygen saturation (SpO₂) under 95%. - No sharp hip or neck bending. - Don't cluster care (bath right after linen change spikes ICP). - Hyperoxygenate before and after suctioning; avoid unneeded suctioning and coughing. - Quiet room, dim lights. - Watch blood pressure (BP), rhythm, SpO₂, glucose, temperature. Box 38.5 signs of ↑ICP: ↓LOC (earliest), restless/irritable/confused, headache, vomiting (may be projectile), speech changes, pupil changes (dilated nonreactive = "blown"), seizures, Cushing's triad and posturing (very late). Meds, blood pressure (BP) & swallowing (book)Read in book BP Critical Rescue: no tissue plasminogen activator (tPA) or embolectomy → BP may be allowed up to 220 systolic. After tPA/embolectomy → report systolic above 180. Avoid a sudden BP drop: it can cause brain ischemia. - Aspirin and clopidogrel = standard for ischemic stroke and preventing the next one. - Anticoagulants (heparin, warfarin, direct oral anticoagulants (DOACs)) for A-fib. High-alert: bleeding risk. - Low-dose aspirin within 24–48 hrs; not within 24 hrs of tPA. Teach to report bruising or bleeding. - Stool softeners (no straining = no intracranial pressure (ICP) spike), pain and anxiety meds. - nothing by mouth (NPO) until a swallow screen. Positive screen → speech-language pathologist. - Weigh daily; check prealbumin; dietitian. - Flaccid arm: support it on a pillow so the shoulder doesn't dislocate (subluxation). Don't pull on it. - Early mobility; prevent deep vein thrombosis (DVT) with compression devices. Aphasia & communication (book)Read in book | Expressive (Broca) | Receptive (Wernicke) | Global (mixed) | | --- | --- | --- | | Frontal lobe. Understands but can't speak (or write). Knows it → frustrated, angry. | Temporoparietal. Can't understand. Can talk, but words are often meaningless. | Both: can't speak and can't understand. Reading and writing are affected the same way. Usually a large stroke involving the left (dominant) side. | "Broca = broken speech. Wernicke = words wacky. Global = gone both ways." - One idea at a time. Simple one-step commands. - Speak slowly, not loudly. Use gestures. - Yes/no questions for expressive aphasia. - Global aphasia: rely on gestures, pictures, touch, and facial expression. Keep a calm tone; watch body language for needs. - Picture boards, tablets, flash cards. Don't rush. - Work with the speech-language pathologist. Vision, neglect & left vs. right (book)Read in book Right-brain stroke (trouble with space and distance, right vs. left): - Use frequent verbal and touch cues; break tasks into small steps. - Approach from the unaffected side. Patient faces the door. Unilateral neglect (usually right-brain stroke): ignores one side. - Teach to touch and use both sides. Dress the affected side first. - Homonymous hemianopsia: teach to turn the head side to side (scan) while eating and walking. Put objects in the field of vision. - Diplopia: patch the affected eye; switch every 2–4 hrs. Left-brain stroke (memory problems): - Reorient to day and time; structured routine with repetition. - Apraxia: give simple, short directions; be patient. Core measures & going home (book)Read in book Core measures (ischemic stroke): venous thromboembolism (VTE) prevention · discharged on antithrombotic · anticoagulant for A-fib/flutter · tissue plasminogen activator (tPA) when eligible · antithrombotic by end of day 2 · discharged on statin · stroke education · rehab assessed. Box 38.6 discharge teaching: - Drugs: name, purpose, dose, timing, side effects. - Climbing stairs, getting in and out of bed, chair, and car safely; using mobility aids. - Who to call with questions; what to do in an emergency. - They're at risk for another stroke. Teach FAST (face drooping, arm weakness, speech difficulty, time to call 911). - Watch for depression or dementia within 3 months (poststroke depression). - Caregivers get overwhelmed → respite, social services, American Stroke Association. - Return demonstrations to check family skills. Book · NCLEX Challenge 38.1 · Select all A client has a left middle cerebral artery embolic stroke. Which findings does the nurse expect? Left brain → right side of the body. The left side controls speech, so dysarthria fits. Ataxia and vertigo point to the back of the brain (vertebrobasilar). Book · NCLEX Challenge 38.2 A client was just admitted to the emergency department (ED) with new-onset ischemic stroke. Which drug does the nurse anticipate? New ischemic stroke in the time window = tPA (after the CT shows no bleed). Aspirin waits 24–48 hrs. Book · Mastery Q1 A client with an acute ischemic stroke is receiving alteplase. Priority nursing action? Bleeding (especially into the brain) is the biggest danger with tPA. Book · NGN Challenge 38.1 Case: 74-year-old with diabetes in the ED. Right arm felt weak and tingly; now feels "more normal." Bilateral carotid bruits. blood pressure (BP) 168/92, heart rate (HR) 88, oxygen saturation (SpO₂) 96%. History: type 2 diabetes, hypertension (HTN), alcohol, 69 pack-year smoking. Glucose 231. Quick recall · tap to flip NCLEX The nurse has an order to start alteplase for a client with stroke symptoms. What must the nurse confirm first? tPA in a hemorrhagic stroke could be fatal. CT first, every time. NCLEX A client just admitted with an ischemic stroke asks for water. What does the nurse do? Aspiration is the most common cause of hypoxia in stroke. Screen first; refer to speech if any concern. NCLEX A client with a right-hemisphere stroke keeps trying to get out of bed alone. Priority problem? Right-brain strokes cause impulsivity and poor judgment. Safety first. NCLEX A client's wife says his face drooped "about 2 hours ago, then got better, now it's back." Most important info for the nurse? tPA eligibility is timed from first symptom onset. The 60-second version ## The skull is a closed box. Swelling has nowhere to go. - Normal intracranial pressure (ICP) 10–15. Over 20 = brain cells die. - cerebral perfusion pressure (CPP) = mean arterial pressure (MAP) − ICP. Keep it above 70. - First sign of ↑ICP = mental status change. Late = Cushing's triad, posturing. - Glasgow Coma Scale (GCS) 8 or less → intubate. A 2-point drop = call. - Head injury → assume neck injury too (jaw thrust). The skull holds 3 things: brain, blood, and cerebrospinal fluid (CSF). It's a full suitcase that can't stretch. If one thing gets bigger (swelling, a bleed, extra fluid), something gets crushed, starting with the blood vessels. Types of brain injury Primary injury = direct damage from the hit. Most common causes: car crashes and falls (teach seat belts, helmets, fall prevention). | Term | Meaning | | --- | --- | | Open head injury | Skull broken/pierced (e.g., gunshot) → infection risk | | Closed head injury | Blunt hit, skull intact. More dangerous: swelling has no escape → ↑intracranial pressure (ICP) | | Contusion | Bruised brain | | Laceration | Torn vessels (inside of skull is bumpy and sharp) | | Diffuse axonal injury | Widespread damage from high-speed crash (speed up, sudden stop) | | Severity | Glasgow Coma Scale (GCS) | Unconscious for | | --- | --- | --- | | Mild (= concussion) | — | Usually sent home | | Moderate | 9–12 | 30 min – 6 hrs | | Severe | 8 or less | Over 6 hrs → intensive care unit (ICU) | Concussion discharge teaching Your instructor: "Don't memorize the list, but know it. You'll get yes/no examples." - Acetaminophen for pain is OK. No nonsteroidal anti-inflammatory drugs (NSAIDs) (Motrin, Advil): bleeding risk. - Return to the emergency room (ER) for signs of ↑intracranial pressure (ICP) (swelling or bleed): worse headache, vomiting, confusion, hard to wake, weakness, seizures, vision changes. - Clear fluid from the nose or ears → return. Could be a cerebrospinal fluid (CSF) leak or skull fracture. The full book list (Box 38.8) is in the "Mild traumatic brain injury (TBI) teaching" chunk below. Secondary injury: hypoxia & ↑intracranial pressure (ICP) Happens after the first hit and makes it worse. End result: brain tissue damaged, blood flow interrupted. - Post-concussion syndrome (mild injury): headaches, dizziness, foggy thinking for weeks to months. - Cerebral hypoxia: from clots, respiratory failure, low blood pressure (BP). Risk for neurogenic shock. Brain perfusion drops when mean arterial pressure (MAP) is under 65–70. ↑ICP numbers: - Normal ICP = 10–15 mmHg. Coughing, sneezing, straining (Valsalva) raise it briefly. OK. - Over 20 for long = neurons die. - cerebral perfusion pressure (CPP) (blood flow to the brain) = MAP − ICP. Goal above 70. Example: MAP 85, ICP 25 → CPP = 60. Too low! The brain isn't getting enough blood. ICP monitors (just recognize the names): ventriculostomy (intraventricular catheter, can also drain cerebrospinal fluid (CSF)) and subarachnoid screw / ICP bolt (placed through a burr hole). Signs of ↑intracranial pressure (ICP) - First: mental status change (restless, confused). level of consciousness (LOC) drop comes later. - Pupil changes: unequal, dilated, non-reactive. Cushing's triad (late sign; near death). Really 4 parts:\ 1\. Severe hypertension\ 2\. Bradycardia\ 3\. Widened pulse pressure\ 4\. Irregular breathing (Cheyne-Stokes) | Decorticate | Decerebrate | | --- | --- | | Abnormal flexion: arms bent in toward the "core" | Abnormal extension: arms straight out. Worse | Both are late signs. Brain bleeds (hematomas) No room in the skull → life-threatening. Your instructor: "kind of something you just have to memorize." | Type | Where | Key sign | | --- | --- | --- | | Epidural | Above the dura ("epi" = above) | Lucid interval: knocked out → wakes up and talks (seems better) → rapidly declines. Emergency surgery. Neuro checks every 5–10 min. | | Subdural | Below the dura ("sub" = below) | Slow: weeks to months. Easy to miss. | | Subarachnoid | Subarachnoid space | "Worst headache of my life," sudden | | Intracerebral | Deep in brain tissue | — | Hydrocephalus & herniation Hydrocephalus = too much cerebrospinal fluid (CSF) (not absorbed, or blocked) → big ventricles → ↑intracranial pressure (ICP). Herniation = brain shifts to make room: - Uncal: sideways (temporal lobe). - Central: downward onto the brainstem. Don't memorize which pupil means which. Know: pupils change (unequal, dilated), always non-reactive → call Rapid Response and the provider. level of consciousness (LOC) drops, Cheyne-Stokes breathing. Assessment after head injury - airway, breathing, circulation (ABCs) first. Assume a cervical spine injury → spinal precautions; open airway with jaw thrust. - Autoregulation is lost: blood pressure (BP) and heart rate (HR) can swing either way. Get a baseline; may seem stable then crash. - Do the neuro exam BEFORE sedatives or paralytics. - Pupils: any change → call right away. - Motor: deficit on the opposite side of the lesion. Skull fracture signs: - cerebrospinal fluid (CSF) leak: clear fluid from nose/ears; positive glucose on dipstick; halo sign. - Battle sign: bruising behind the ear (mastoid). - Raccoon eyes: bruising around the eyes. Glasgow Coma Scale practice Your instructor: don't memorize the scale. You'll be given it; know how to apply it. - Highest = 15. Lowest = 3. - 7 or less = coma. "Less than 8, intubate." - A 2-point drop = clinically significant → Rapid Response / provider. Eyes open Verbal Motor Preloaded with the class example: opens eyes to pain (2) + withdraws (4) + moans (2) = 8. Interventions to lower intracranial pressure (ICP) Respiratory: prevent low oxygen, and keep carbon dioxide (CO₂) 35–45. "High CO₂ dilates, low CO₂ constricts." High → brain vessels swell → ↑ICP. Low → vessels clamp → poor blood flow. Both bad. - Cardiovascular: know the patient's blood pressure (BP) range; call if above or below. Cardiac monitor (lost autoregulation → dysrhythmias). - Therapeutic hypothermia: cooling lowers the brain's oxygen demand. Mannitol (osmotic diuretic): - Pulls water out of brain tissue into the blood → kidneys pee it out → less swelling, lower ICP. - Dosed by serum osmolality; goal 310–320 (normal \~300), slightly "salty" blood. - Watch: dehydration, electrolyte imbalance, acute kidney injury. Foley + hourly I&O (an exception to avoiding Foleys). - Often given with furosemide: mannitol pulls fluid from the brain, furosemide removes it from the body. Hypertonic saline (3% or 5%) works like mannitol. intensive care unit (ICU) only, and it shows why it's dangerous for regular patients. Your instructor said a case study (due next week, from the book) covers ICP prevention in detail, plus post-op craniotomy care. Brain tumors & craniotomy - Primary = starts in the brain. Secondary = spread from elsewhere (lung, breast). - Any tumor → ↑intracranial pressure (ICP) and squeezes brain tissue and vessels. - Meningioma (benign, common) → usually removed with a good outcome. Malignant → surgery + radiation/chemo. - Common signs: headache, seizures, dizziness, memory loss. | Craniotomy | Decompressive craniectomy | | --- | --- | | Skull opened, fixed, closed right away | Piece of skull removed and frozen; put back weeks/months later. Leaves room to swell. Patient wears a helmet. | Read in book Iggy Ch. 38, pp. 956–973 · skipped per your list: chronic traumatic encephalopathy (CTE) paragraph, pinpoint/ovoid pupil sentences, supra/infratentorial paragraph, chemo & direct drug delivery traumatic brain injury (TBI) basics (book)Read in book - TBI = brain damage from an outside force. Affects cognition, movement, senses, and emotions. - Acceleration injury = something hits the still head. Deceleration = moving head hits something still. Shearing → diffuse axonal injury. - Open = skull or dura broken (infection risk). Closed = skull intact. - Top causes: falls, self-harm, car crashes, assaults. Alcohol/drugs contribute. Young men most; falls most in older adults and kids. | Mild (concussion) | Moderate | Severe | | --- | --- | --- | | Blow to the head + brief confusion or feeling dazed, plus one or more: out up to 30 min, memory loss right before/after, focal neuro deficit. Doesn't need loss of consciousness. computed tomography (CT)/magnetic resonance imaging (MRI) normal. Symptoms usually gone in 72 hrs. | Out 30 min–6 hrs; Glasgow Coma Scale (GCS) 9–12. CT/MRI often shows injury. Memory loss up to 24 hrs. Short acute/critical care stay to watch for swelling, bleeding. | GCS 3–8; out over 6 hrs. Critical care: hemodynamic, neuro, possibly intracranial pressure (ICP) monitoring. High risk for secondary injury. | - Postconcussion syndrome (most common secondary injury after mild TBI): headache, foggy thinking, dizziness for 4+ weeks. Also posttraumatic headaches or vertigo; irritability, depression, anxiety, mood swings; insomnia; trouble concentrating or memory loss; lower alcohol tolerance. - Second-impact syndrome: a second hit before the brain heals → rapid brain swelling, can be catastrophic. Mostly athletes. Teach return-to-play rules. Secondary injury numbers (book)Read in book - Hypotension = mean arterial pressure (MAP) under 70. Hypoxemia = partial pressure of arterial oxygen (PaO₂) under 80. Both starve the brain → swelling → worse perfusion (vicious cycle). - intracranial pressure (ICP) normal 10–15; coughing or straining spikes are OK. Sustained over 20 → neurons die. - Body compensates: shifts cerebrospinal fluid (CSF), absorbs more CSF, moves venous blood out. When it can't, ICP rises → herniation. - ↑ICP is the leading cause of death in head-trauma patients who reach the hospital alive. Bleeds & herniation (book)Read in book | Bleed | Book detail | | --- | --- | | Epidural | Arterial (middle meningeal artery), often a temporal skull fracture. Brief unconsciousness → lucid interval (awake, talking for minutes) → rapid decline. Critical Rescue: neuro checks every 5–10 min; loss of consciousness = neurosurgical emergency → provider/Rapid Response now. Document trends. | | Subdural (SDH) | Venous, slower. Acute (within 48 hrs), subacute (48 hrs–2 wks), chronic (weeks–months). Common in older adults and people on anticoagulants/antiplatelets. Signs: worsening headache, confusion, ↓level of consciousness (LOC). | | Intracerebral (ICH) | Bleeding into brain tissue; may appear up to 10 days later. | - Uncal herniation: pushes on cranial nerve (CN) III → dilated nonreactive pupil, ptosis, fast LOC decline. - Central herniation: downward onto the brainstem → Cheyne-Stokes breathing, then nonreactive pupils, unstable vitals. - All herniations are life-threatening → Rapid Response / provider immediately. - Hydrocephalus: communicating = cerebrospinal fluid (CSF) not absorbed (after subarachnoid hemorrhage (SAH) or meningitis); noncommunicating = outflow blocked (swelling, tumor, debris). traumatic brain injury (TBI) assessment (book)Read in book - History: when, where, how; lost consciousness, and how long? Get it from witnesses if needed. Amnesia is common. Older adults: screen for abuse/neglect. - carbon dioxide (CO₂): high (over 45) → vasodilation → ↑intracranial pressure (ICP). Low (under 35, from hyperventilating) → vasoconstriction → ischemia. Track with end-tidal carbon dioxide (ETCO₂). - Treat as a cervical spine injury until x-rays prove otherwise. Rigid collar; spine precautions: bed rest, no neck or back bending or twisting, log roll, check skin under the collar. Spine "clearance" is the provider's call. - Brainstem injury → Cheyne-Stokes or apnea; may need a ventilator. - Cushing's triad = severe hypertension (HTN), widened pulse pressure, bradycardia → death is near. - Glasgow Coma Scale (GCS) change of 2 points = report. level of consciousness (LOC) is the most important thing to assess; a change is the first sign of worsening. - Pupils: unequal, sluggish, or dilated = herniation until proven otherwise. Fixed and dilated ("blown") = poor prognosis. - Check vision (read your name tag, count fingers). - Late ↑ICP signs: severe headache, vomiting (often projectile), seizures. Papilledema = always ↑ICP. - Highest ICP risk: first hours, up to 3–4 days after injury. - Motor loss is on the opposite side. - cerebrospinal fluid (CSF) leak: clear fluid from nose/ear, positive glucose, halo sign on white gauze. Raccoon eyes, Battle sign = basilar skull fracture. - computed tomography (CT) first. magnetic resonance imaging (MRI) shows diffuse axonal injury but not with ICP monitors. Critical Rescue: check pupils (size, shape, reaction) often, especially if they can't follow directions. Report any change to Rapid Response; it may mean ↑ICP. traumatic brain injury (TBI) interventions (book)Read in book - Vitals every 1–2 hrs or more. Report dysrhythmias, high or low blood pressure (BP); get target ranges from the provider. - Fever = worse outcomes. Goal is normal temperature (targeted temperature monitoring). - Keep partial pressure of arterial carbon dioxide (PaCO₂) normal; avoid over-hyperventilating. Positioning Action Alert: head midline, no extreme neck flexion/extension. Log roll. head of bed (HOB) at least 30° (or as ordered). Avoid sudden HOB changes; a big BP drop when sitting up can hurt the brain. Mannitol (book adds): - Pulls water out of swollen brain tissue. Works best as boluses, not a continuous drip. - Give through a filter in the intravenous (IV) tubing, or draw up with a filtered needle for IV push (removes tiny crystals). - Serum electrolytes and osmolarity every 6 hrs; goal osmolarity 310–320. Serum and urine osmolarity and sodium checked at least daily. - Strict hourly urine output, I&O. Watch for severe dehydration, acute kidney failure, weakness, edema, urine output changes. - Furosemide (loop diuretic) is often added: prevents mannitol "rebound," boosts its effect, lowers edema and blood volume, and reduces cerebrospinal fluid (CSF) production. Hypertonic saline (HTS): draws fluid out like mannitol. Usually 3% sodium chloride (NaCl) (can be up to 23%). Nursing: constant neuro checks, serial sodium levels, fluid status, watch for pulmonary edema (especially heart or kidney disease). Some hospitals require intensive care unit (ICU) + central line. Evidence box: HTS is at least as effective as mannitol for lowering intracranial pressure (ICP); some studies say better. Choice depends on the patient. Opioids (fentanyl, morphine) and sedation (propofol, dexmedetomidine) may help ventilated patients; check neuro first. Brain death requires: coma of known cause, temp above 96.8°F (36°C), systolic ≥100, at least 1 neuro exam. Before it's declared, call the organ procurement agency (the nurse doesn't bring up donation alone). Support grieving families; ethics, chaplain, social work. Cognition, seizures & trauma-informed care (book)Read in book - Memory and thinking: cognitive rehab; reorient; hazard-free room. - Sensory stimulation for comatose patients: one stimulus at a time (show a family photo and say who it is). Audio no longer than 10–15 min or it becomes "white noise." - Seizure precautions and antiepileptic drugs (AEDs) as ordered. - Trauma-informed care (6 principles): safety, trust and transparency (plain language), peer support, collaboration, empowerment (patient has a voice), cultural and historical sensitivity. Mild traumatic brain injury (TBI) teaching: Box 38.8Read in book - Headache → acetaminophen every 4 hrs as needed (no nonsteroidal anti-inflammatory drugs (NSAIDs)). - No sedatives, sleeping pills, or alcohol for at least 24 hrs (unless the provider says otherwise). - No strenuous activity for at least 48 hrs. - Caregiver: balance problems can cause falls; plan safe movement. - Call 911 / return for: seizure, severe or worsening headache, persistent vomiting, blurred vision, clear drainage from ear or nose, increasing weakness, slurred speech, progressive sleepiness, unequal pupils. - Keep follow-up appointments. Home care after traumatic brain injury (TBI) (book)Read in book - Rehab goal: highest possible function (OT, physical therapy (PT), speech). - Home safety: working smoke and fire alarms; brain injury often takes away the sense of smell. - Dietitian: many gain weight within a year (inactivity, stress eating). - Personality and behavior changes: structured, consistent routine with repetition. Reinforce positive behavior. - Expect fatigue, irritability, temper outbursts, depression, memory problems. Some need constant supervision. - Families feel isolated → regular respite, support groups (Brain Injury Association of America). Brain tumors (book)Read in book - Primary tumors start in the central nervous system (CNS) and rarely spread out of it. Secondary tumors spread from lung, breast, kidney, skin, gastrointestinal (GI). - Any tumor → swelling, ↑intracranial pressure (ICP), possible herniation. Pituitary tumors can cause syndrome of inappropriate antidiuretic hormone (SIADH) or diabetes insipidus (fluid and sodium problems). - Meningiomas (benign) can usually be removed with a good outcome. - Malignant tumors mostly at ages 40–70. Signs: headache worse on waking, nausea/vomiting, seizures, numbness or vision changes, dizziness, one-sided weakness, trouble speaking, personality changes. Diagnosis: computed tomography (CT) first, then magnetic resonance imaging (MRI) for detail. Symptom meds: - Codeine/acetaminophen for headache. - Dexamethasone (steroid) for brain swelling. - Levetiracetam or other antiepileptic drugs (AEDs) to prevent seizures. - proton pump inhibitors (PPIs) to prevent stress ulcers. Gamma Knife / CyberKnife (stereotactic radiosurgery): focused radiation, no incision, for hard-to-reach tumors or arteriovenous malformations (AVMs). Tumor Treating Fields: electric fields through skin pads. Glioblastoma = most aggressive; few survive 5 years. Craniotomy care (book)Read in book Before surgery: very anxious (head opened, hair shaved, fear of new deficits). Reassure; teach what to expect after. Action Alert: neuro checks + vitals every 15–30 min for 4–6 hrs, then hourly. Stable 24 hrs → every 2–4 hrs. Report: ↓level of consciousness (LOC), new weakness or paralysis, aphasia, less feeling, sluggish pupils, agitation, personality change. | Supratentorial (top of brain) | Infratentorial (brainstem/back) | | --- | --- | | head of bed (HOB) 30° (venous drainage). Head midline; no extreme hip or neck bending. Turn side to side or supine. | Keep flat or 10°. Side-lying, alternating every 2 hrs, for 24–48 hrs. nothing by mouth (NPO) until fully awake (swelling near medulla → vomiting, aspiration). | - Check the head dressing every 1–2 hrs; mark drainage once a shift. - Drain (Hemovac/Jackson-Pratt (JP)): measure every 8 hrs; usually 30–50 mL / 8 hrs. Critical Rescue: report a saturated dressing or drainage over 50 mL in 8 hrs right away. Watch for ↑intracranial pressure (ICP). - Swollen, bruised eyes are normal → cool compresses; rinse with warm saline or artificial tears. - Cardiac monitor (dysrhythmias). Strict I&O for 24 hrs; fluid limit \~1500 mL/day if the pituitary is involved. - Labs: complete blood count (CBC), electrolytes, osmolality, clotting. Watch for low sodium (SIADH, steroids) → confusion, weakness. High sodium (DI, dehydration) → thirst, restlessness. - venous thromboembolism (VTE): compression devices until walking. Deep breathing every 2 hrs. Box 38.9 complications: - Early: ↑ICP, hematomas, subarachnoid hemorrhage (SAH), hypovolemic shock, hydrocephalus, breathing problems (atelectasis, pneumonia, neurogenic pulmonary edema). - Late: wound infection, meningitis, fluid/electrolyte problems, seizures, cerebrospinal fluid (CSF) leak, cerebral edema. Book · NCLEX Challenge 38.4 A client just returned from an open craniotomy for a frontal lobe tumor. Which finding needs immediate report to the surgeon or Rapid Response? ↓level of consciousness (LOC) = possible ↑intracranial pressure (ICP) or bleeding. Headache and eye swelling are expected; 25 mL is under the 50 mL limit. Book · NCLEX Challenge 38.3 A client with a mild traumatic brain injury (TBI) is learning about home care. Which statement shows a need for more teaching? Box 38.8: no strenuous activity for at least 48 hrs, and balance problems make construction work unsafe. The others are correct teaching. Book · Mastery Q3 Which finding is an early change in LOC in a client with a mild TBI? Behavior changes (irritable, restless) come first. Posturing and lost reflexes are late. Book · Mastery Q2 · Select all The nurse is giving mannitol to a client with a severe TBI. Which actions are appropriate? Only A is wrong: urine output is measured every hour, not every 4–8. Filtered needle, electrolytes, osmolarity, and dehydration watch all match p. 964. (My answer; check your book's key.) Book · NGN Challenge 38.2 Case: 79-year-old fell at home 2 days ago and broke her right arm. Over 2 days: Glasgow Coma Scale (GCS) 15 → 14, headache 4 → 5 → 8/10, blood pressure (BP) and pulse creeping up. Review class: Joline head-injury case (what she stressed) Review class From the in-class exam review (Joline case study + NCLEX questions). Joline fell from a third-story balcony. Think: head injury and spine injury until proven otherwise. 1. Most important thing to monitor: level of consciousness (LOC). First sign of trouble = changes in behavior. 2. Cushing's triad (the "triad" that has 4 parts): severe hypertension, widened pulse pressure, bradycardia, irregular breathing. Normally high blood pressure makes the heart speed up, so slow heart rate + high blood pressure is the weird exception. It is a late sign of increased intracranial pressure. Be able to apply it: "blood pressure 200/80, heart rate 40" = Cushing's. 3. Neuro assessment, know what's wrong AND how you check it: pupils equal, round, reactive to light and accommodation (PERRLA), LOC, Glasgow Coma Scale (GCS), motor (squeeze my hands, push/pull feet, raise arms), sensory, reflexes, cranial nerves, vital signs (which part is off and why), breathing pattern. 4. Orogastric (OG) tube, not nasogastric (NG), with severe facial trauma or skull fracture (like basal skull fracture). A tube through the nose could go up through the fracture into the brain. Going through the mouth avoids that. 5. Blood alcohol makes the neuro assessment unreliable. 6. When she wakes up: first tell her where she is and what happened ("You're in the hospital. You were in an accident."). This lowers fear. Then check orientation. (Students often pick "ask where she is." That's second.) 7. Epidural hematoma: knocked out right away → lucid interval (seems better, "it's a trick") → then crashes. 8. Bruising and swelling around the eyes (periorbital edema and ecchymosis) is expected with this injury. Apply cold compresses (decrease swelling) and artificial tears (comfort). Assess, and notify the provider as needed. 9. 3 reasons for a fever: infection, inflammation (body's response to brain injury), and damage to the hypothalamus (the body's thermostat). Glasgow Coma Scale: don't memorize the scale. The test will give it to you. Just know how to apply it. The tricky part is motor: withdraws / pulls in = 4. Pushes the stimulus away = 5 (localizes pain). Her examples: eyes to pain 2 + verbal none 1 + withdraws 4 = 7. Eyes to sound 3 + incomprehensible sounds 2 + localizes 5 = 10. Review class: spinal precautions + preventing ↑intracranial pressure (ICP) Review class From the in-class exam review (Joline case study + NCLEX questions). Backboard and cervical collar: used because spinal cord injury and head injury go together. They stay until spinal cord injury is ruled out. - Spinal precautions: supine (bed rest), spine in neutral position. No twisting, no neck flexion forward or back, no pillow. - Remove the long backboard as soon as possible: go back to basics: a hard board causes skin breakdown. - Repositioning = log roll as a unit, with help. - Every time the patient is moved (turns every 2 hrs, trip to head computed tomography (CT) scan), do another neuro assessment. - Head of bed position depends on cerebral perfusion pressure (CPP). Up can pull blood away from the brain; flat can send too much and raise ICP. It's individualized. Don't memorize the book's exact rules; just know CPP guides the choice. Nursing care to avoid increasing ICP: 1. Quiet, calm room. Noise, bright light, anxiety, agitation all raise ICP. Limit upsetting visitors (a screaming parent may need to step out). 2. No Valsalva (bearing down): give stool softeners; manage coughing. 3. Suction only if you must (airway, breathing, circulation (ABCs) come first). Try repositioning and other measures first. If you suction, hyperoxygenate first. 4. Keep the whole body straight: no head flexion, no pillow under the knees (bent knees block blood flow back from the head). 5. Frequent vital signs + neuro checks. 6. Arterial blood gas (ABG): watch carbon dioxide (CO₂) closely. CO₂ is a potent vasodilator → more blood in the brain → ↑ICP. 7. Do NOT cluster care. Exception to the rule! Repositioning + bath + linen change + suppository all at once = ICP spike. Space activities out. 8. Control fever. Fever → shivering → more oxygen demand → more CO₂ → vasodilation → ↑ICP. 9. Mannitol (see below). | Mannitol: know it cold | | | --- | --- | | Class | Osmotic diuretic | | How it works | Treats brain swelling. Pulls water out of the brain tissue into the blood vessels → kidneys excrete it. Sometimes given with furosemide (loop diuretic) to work together. | | Dosing guide | Serum osmolality. Normal ≈ 300 (just remember 300). Goal = slightly hypertonic, 310–320. Pump rate is adjusted to stay there. | | Filter needle | Always. It has microscopic crystals. Any time you read "use a filter needle," remember it. | | Monitor | Intake and output (I&O); urinary catheter is often used here (an exception, we usually avoid catheters); dehydration; blood pressure; labs: sodium, potassium, serum osmolality | Legal/ethical (organ donation): Joline is an adult whose driver's license says organ donor. In Michigan, Ohio, and Kentucky that is legally binding, so the hospital follows it even if family disagrees (it varies by state). Help the grandmother: let her express feelings; involve the chaplain, social services, organ donation team, and possibly the ethics committee. Quick recall · tap to flip NCLEX A client hit his head, was knocked out, then woke up talking normally. An hour later he's hard to wake. The nurse suspects: Lucid interval then rapid decline = epidural. Emergency surgery. NCLEX MAP 80, ICP 22. What is the CPP, and what does the nurse do? 80 − 22 = 58. Under 70 means poor brain perfusion, and ICP over 20 is dangerous. NCLEX A client's GCS dropped from 13 to 11. Best action? A 2-point drop is clinically significant. NCLEX Which finding in a client on mannitol needs follow-up first? Mannitol should cause big diuresis. Very low output suggests acute kidney injury. NCLEX Clear fluid is draining from a head-injury client's nose. Best assessment? CSF contains glucose and forms a halo on gauze. Possible skull fracture. The 60-second version ## Migraine = overexcited nerves + swollen, widened brain blood vessels - One-sided, throbbing pain. Nausea. Light and sound hurt. Some get an aura first. - Pain management is the priority. First step: avoid triggers. - Most migraine meds work by narrowing the blood vessels. - Triptans: NO for heart disease, high blood pressure (BP), peripheral vascular disease (PVD), or with selective serotonin reuptake inhibitors (SSRIs). The vessels are like a garden hose that's swollen too wide and throbbing. The fixes squeeze the hose back down: caffeine, triptans, even a cool cloth. Signs & finding the cause - Usually one-sided, throbbing. - Nausea, photophobia, phonophobia. - Aura = warning before it hits (vision changes). Nurse's job: detailed interview. How often? How long? What sets it off? Headache diary → finds patterns and triggers. Common triggers: caffeine, red wine, monosodium glutamate (MSG) (a food flavor additive). Treatment step 1 & 2: triggers + comfort 1. Avoid triggers. 2. Comfort measures: lie down in a dark room, cool cloth on the forehead, relaxation, yoga, massage, acupuncture. 3. Medications if still needed. Abortive meds (stop it now) Take as soon as symptoms start, ideally during the aura. - First: acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs) (ibuprofen, naproxen), or over-the-counter (OTC) combos with caffeine (like Excedrin). Caffeine narrows blood vessels. - Next: triptans, like sumatriptan (Imitrex) and rizatriptan (Maxalt). They activate serotonin → narrow brain arteries → less pain. Triptan safety: they narrow vessels everywhere, not just the brain.\ • Think twice with high blood pressure (BP) or heart disease.\ • Peripheral vascular disease: absolutely not.\ • Teach: report chest pain right away (heart not getting enough blood).\ • Don't mix with selective serotonin reuptake inhibitors (SSRIs) (sertraline, fluoxetine) or St. John's wort → serotonin syndrome. Lasmiditan: newer, doesn't narrow vessels outside the brain, so safer. Side effects: sleepiness, dizziness. Rebound headache: a new headache after the first one goes away. Caused by taking the medicine too often or too much. Preventive meds (stop it from coming) For migraines that are frequent or severe: - nonsteroidal anti-inflammatory drugs (NSAIDs) - Beta blockers - Topiramate (an anti-seizure drug) Read in book Iggy Ch. 36, pp. 899–902 · crossed-out parts skipped Migraine basics (book)Read in book - Recurrent attacks of head pain that serve no protective purpose. - Throbbing, unilateral. Nausea + sensitivity to light, sound, or head movement. - Lasts 4 to 72 hours. Runs in families. Women more than men. - Linked to major depression, and higher risk of stroke and epilepsy. How the pain happens: cerebral arteries dilate → prostaglandins released → inflammation, swelling, leaking → throbbing pain. Full trigger listRead in book - Caffeine, red wine, monosodium glutamate (MSG) - High-intensity light, stress, excessive fatigue, change in weather - Tyramine: pickled foods, aged cheese, smoked sausage, beer - Preservatives, artificial sweeteners Triggers set off hyperexcitable neurons. Each patient's triggers are different. Types & phases (Box 36.8)Read in book | With aura ("classic") | Without aura ("common") | | --- | --- | | Aura right before the headache | Most migraines are this type | Chronic = 15+ days a month. Episodic = less often. 1. Prodrome (1–2 days before): yawning a lot, constipation, mood changes, food cravings. 2. Aura (5–60 min, usually one-sided): flashing lights, spots, zigzag lights; numb or tingling lips/tongue, confusion, aphasia, vertigo, one-sided weakness, drowsiness. 3. Migraine phase: nausea/vomiting; one-sided throbbing pain, often worse behind one eye or ear; photophobia, phonophobia. Without aura: pain gets worse with routine activity; often early morning, with stress, or premenstrual. Diagnosis: history + physical, neuro, and psych assessment. Patients tend to have the same symptoms each time. Women over 50 with migraines: teach cardiovascular risk factors. Call 911 for facial drooping, arm weakness, or trouble speaking (stroke). Abortive drugs: the full lineupRead in book Priority of care = pain management. | Severity | Drugs | | --- | --- | | Mild | Acetaminophen; nonsteroidal anti-inflammatory drugs (NSAIDs) (ibuprofen, naproxen); over-the-counter (OTC) nonsteroidal anti-inflammatory drug (NSAID) + caffeine | | Nausea | Antiemetics; metoclopramide with NSAIDs (speeds stomach emptying) | | Severe | Triptans, ditans | Caffeine narrows vessels by blocking adenosine (which widens vessels and adds inflammation). Triptans (sumatriptan, eletriptan, naratriptan, almotriptan) activate 5-HT (serotonin) receptors → vasoconstriction. Sumatriptan comes as a pill, injection, or nasal spray. Contraindicated: ischemic heart disease, cerebrovascular ischemia, hypertension (HTN), peripheral vascular disease (PVD), Prinzmetal angina (coronary vasospasm risk). Triptan teaching (Drug Alert): take as soon as symptoms start · report chest pain right away · use birth control (not safe in pregnancy) · expect flushing, tingling, hot feeling that fades · no selective serotonin reuptake inhibitors (SSRIs) or St. John's wort. Ditans (lasmiditan): block one serotonin receptor without constricting vessels → safer and more effective than triptans. When to start preventive drugsRead in book Start prevention when any of these is true: - More than 2 migraines a month - Headache lasts more than 24 hours - Interferes with activities of daily living (ADLs) for 3+ days - Abortive meds used more than twice a week - Not relieved by acute treatment | Drug | Key point | | --- | --- | | Beta blockers (propranolol, timolol) | Calm hyperexcitable neurons, block vasodilation. Lower blood pressure (BP) and heart rate (HR). | | Calcium channel blocker (verapamil) | | | Topiramate (AED) | Use in low doses | | Nortriptyline (TCA) | Dry mouth, urinary retention, constipation. Not for older adults (delirium). | beta blocker (BB) / calcium channel blocker (CCB) teaching: take your pulse · report bradycardia, fatigue, shortness of breath · change position slowly (orthostatic hypotension). Diary, comfort & complementary careRead in book - Headache diary: type of headache + response to meds. - Report if the headache changes in quality or intensity, has new visual changes, or the drug stops working. - At onset: lie down, dark room, both eyes covered, cool cloth, undisturbed. - Cannabis: cannabidiol (CBD) eases pain better; tetrahydrocannabinol (THC) is the mind-altering part. Tolerance can develop. - Yoga, meditation, massage, exercise, biofeedback, acupuncture/acupressure. - Riboflavin and magnesium supplements may help prevent migraines. - All herbs must be approved by the provider first (drug interactions). Heads-up: the book prints "vitamin B12 (riboflavin)," but riboflavin is actually vitamin B2. Book · NCLEX Challenge 36.4 · Select all Client prescribed propranolol (prevention) and sumatriptan (acute). Which teaching statements should the nurse include? Beta blockers cause bradycardia (report a LOW pulse, not >100) and orthostatic hypotension. Triptans go in early, and chest pain = possible ischemia. Vitamin D isn't part of this plan. Review class: migraine meds (prevent vs. abortive) Review class From the in-class exam review (Joline case study + NCLEX questions). | Goal | Drug | Key point | | --- | --- | --- | | Prevent migraines | Propranolol (beta blocker) | Taken regularly to prevent attacks | | Abortive (once headache starts) | Triptans (sumatriptan): "triptan" is in the name | Activates serotonin → vasoconstriction of the dilated brain vessels | Triptans squeeze blood vessels. They don't only squeeze the brain's vessels, they squeeze them everywhere. Do NOT give triptans with: - Hypertension, peripheral vascular disease (vessels already narrowed) - Angina / heart disease: chest pain after a triptan = coronary vasoconstriction - Selective serotonin reuptake inhibitors (SSRIs) like fluoxetine (Prozac), paroxetine → too much serotonin = serotonin syndrome - St. John's wort (and grapefruit) interact with lots of meds. If it shows up as an answer choice, don't pick it. Quick recall · tap to flip NCLEX A client is prescribed sumatriptan. Which history should the nurse report first? Triptans narrow blood vessels, which makes PVD worse. NCLEX After taking a triptan, the client says "my chest feels tight." What does the nurse do? Narrowed vessels can starve the heart of oxygen. Chest pain is a red flag. NCLEX Which statement shows the client understands migraine self-care? The diary finds triggers. Meds go early, daily use causes rebound headaches, and red wine is a trigger. The 60-second version ## A seizure is an electrical storm in the brain - Seizure with a clear cause (fever, electrolytes, alcohol withdrawal, brain injury) = NOT epilepsy. Treat the cause. - Epilepsy = seizures that keep coming back on their own. - During a seizure: turn to side, move objects, never restrain, nothing in the mouth. - Status epilepticus (>5 min) = emergency → airway first, then lorazepam intravenous (IV). Think of a power surge in a house. Anti-seizure meds are surge protectors: they keep surges from happening, but they don't rewire the house (no cure). Caption alert: the video captions say "fentanyl," but your instructor means phenytoin (Dilantin). "Phosphantinoin" = fosphenytoin. Seizure vs. epilepsy Seizure = sudden, uncontrolled burst of electrical activity in brain cells. Secondary causes (fix these first): high fever, electrolyte imbalance, alcohol withdrawal, brain injury. These are NOT epilepsy. Epilepsy = chronic, recurrent, unprovoked seizures. Cause: abnormal brain cells or a chemical imbalance (like gamma-aminobutyric acid (GABA), the brain's calming chemical). Diagnosis starts with a detailed history and physical. Seizure types (slides)Slides Your instructor said these are review from Peds. You won't be tested on each type directly, but the words may show up in a question. Generalized = both sides of the brain: - Tonic-clonic (2–5 min): stiffening + level of consciousness (LOC) (tonic), then rhythmic jerking (clonic). Tongue biting, incontinence. - Myoclonic: quick jerks of arms or legs. - Atonic: suddenly goes limp → falls → injury. - Absence: brief blank stare; lip smacking or picking (automatisms). Partial (focal) = one side: complex (blacks out 1–3 min, no memory after) or simple (stays awake, has an aura). electroencephalogram (EEG) test prep EEG records the brain's electrical activity. Electrodes are glued to the scalp. - Clean hair: no conditioner, gel, or spray (electrodes won't stick). - Eat before the test. Low blood sugar changes the reading. - No sedatives, stimulants, or caffeine. - Quiet room, sign on the door. We want a picture of the brain's normal self. Anything that speeds it up, slows it down, or starves it ruins the picture. Anti-seizure meds Slide drugs: phenytoin (Dilantin), carbamazepine (Tegretol), valproic acid (Depakote), topiramate (Topamax). You don't need to know which drug is for which seizure type. Know these rules: - They slow the brain → drowsiness. - Can cause depression and suicidal thoughts. Screen mood. - Liver damage → check liver enzymes. Low white blood cells (WBCs) → infection risk. - Narrow safe range → regular blood levels. - Phenytoin → gums overgrow (gingival hyperplasia). Teach: soft toothbrush, regular dentist visits. Never stop suddenly. Seizures come back and can turn into status epilepticus. - Pregnancy category D: can cause birth defects, but uncontrolled seizures hurt the baby too. Tough decision with the provider. - Birth control pills work less well → use a second method. - Warfarin needs close monitoring. No grapefruit (toxicity). Vagal nerve stimulator (VNS) For seizures meds can't control. A device in the left chest (like a pacemaker) sends pulses up the vagus nerve to the brain. - Feels an aura? Swipe the magnet over the device to stop the seizure. - Like a pacemaker: magnetic resonance imaging (MRI) can be dangerous, sets off airport metal detectors, wear a medical alert bracelet, carry a wallet card. Before: seizure precautions - Suction + oxygen at the bedside. - intravenous (IV) access (saline lock). They can't swallow pills during a seizure. - Padded side rails? Debated (could count as a restraint). Follow hospital policy. Some use a mattress on the floor. - Keep them active and independent. Don't keep them stuck in bed. NO padded tongue blades. A chipped tooth can be breathed in, or the blade can block the airway. During a seizure Patient safety is the priority. 1. Turn to the side so spit drains out → no aspiration. 2. Move objects away so they don't get hurt. 3. Never restrain. Nothing in the mouth. 4. Watch and document what happens, in order. It tells the provider the seizure type → which drug. Status epilepticus: emergency Seizure lasting longer than 5 minutes, or seizures back-to-back over 30 minutes. Over 10 minutes can be deadly. Call the Rapid Response Team. 1. Airway (may need intubation) + oxygen. 2. intravenous (IV) with normal saline. Draw blood: arterial blood gases (ABGs), electrolytes, drug levels. 3. Stop it: lorazepam (Ativan) or diazepam (Valium) IV push. 4. Prevent the next one: fosphenytoin (preferred, safer) or phenytoin. Firefighter first (lorazepam puts out the fire). Then the sprinkler system (fosphenytoin stops the next fire). Patient & family teaching - Meds: take every dose, know interactions, keep blood level appointments. - Family knows what to do during and after a seizure, and when to call 911. - Seizure diary. Medical alert bracelet or card. - Driving laws by state: Michigan = 6 months seizure-free · Wisconsin = 3 months · Ohio = no waiting period. - Employment concerns → refer to social services / case manager. - Support groups: Epilepsy Foundation. Read in book Iggy Ch. 36, pp. 902–907 · crossed-out parts skipped (seizure types, Table 36.2) Definitions & secondary causesRead in book Seizure = sudden, excessive, uncontrolled electrical discharge of neurons → changes in level of consciousness (LOC), motor/sensory ability, or behavior. Epilepsy = chronic, repeated, unprovoked seizures. Cause: abnormal electrical activity and/or neurotransmitter imbalance, especially gamma-aminobutyric acid (GABA). Primary (idiopathic): no clear cause, likely genetic. Secondary: from a brain lesion (tumor, trauma) or: - Metabolic disorders, electrolyte problems (hyperkalemia, water intoxication, hypoglycemia) - Acute alcohol withdrawal, substance abuse - High fever, stroke, head injury, heart disease Triggers: more physical activity, stress, fatigue, alcohol or caffeine, certain foods or chemicals. Assessment & diagnosisRead in book - How many seizures, how long, any pattern? Have family describe them. - Any aura before (the preictal phase)? - Meds, herbs, head trauma, high fever, alcohol or drug use, past stroke or hypertension (HTN). - New seizures: ask about any past loss of consciousness or brain injury, even in childhood. Tests: electroencephalogram (EEG), computed tomography (CT), magnetic resonance imaging (MRI), single-photon emission computed tomography (SPECT)/positron emission tomography (PET). antiepileptic drug (AED) teaching (book adds)Read in book - Provider adds one AED at a time. - Keep lab appointments: complete blood count (CBC) + liver enzymes (most antiepileptic drugs (AEDs) cause leukopenia and liver dysfunction) + drug levels. - Take on time. Sensitivity can build with age ("drug decline and sensitivity") → frequent levels. - Phenytoin + warfarin = don't combine. - Grapefruit juice raises drug levels → toxicity. Women with epilepsy: hormones and birth control pills change AED effects → monitor more often. AEDs can add to osteoporosis after menopause. During a seizure: Box 36.9Read in book - Protect from injury; nothing forced in the mouth. - Turn to the side (prevents aspiration, keeps airway clear). - Remove objects; suction gently if possible; loosen clothing. - Don't restrain; guide movements if needed. - Record start and end time. After: vital signs, neuro checks, keep on side, let them rest. Document: pupils and eye deviation, level of consciousness (LOC), apnea/cyanosis/salivation, incontinence, eye fluttering, how motor activity spread, lip smacking, tongue biting, length, aura, behavior after, time to return to baseline. Cyanosis during tonic-clonic seizures is common and usually self-limiting. High-risk patients may get O₂ postictally. Status epilepticus: book detailsRead in book Acute seizures (more intense, more often, or in clusters) → lorazepam or diazepam to prevent status. Common causes of status: suddenly stopping antiepileptic drugs (AEDs), infection, alcohol/drug withdrawal, traumatic brain injury (TBI), cerebral edema, metabolic problems. Critical Rescue: airway is the priority → call provider / Rapid Response → O₂ → large-bore intravenous (IV) with 0.9% sodium chloride (NaCl) → usually intensive care unit (ICU). Untreated: hypoxia, hypotension, hypoglycemia, dysrhythmias, lactic acidosis. Muscle breakdown → myoglobin → acute kidney injury (especially older adults). - Lorazepam IV push over 2 minutes (may repeat). Diazepam rectal gel is an option. - Phenytoin IV: infusion pump · normal saline only (precipitates in other fluids) · flush normal saline (NS) before and after · then oral doses. - Fosphenytoin: water-soluble, works with most IV fluids including dextrose, fewer heart complications. vagal nerve stimulator (VNS): book detailsRead in book - Device in the left chest wall, lead on the left vagus nerve. \~2 hrs under general anesthesia. - Turned on in the operating room (OR) or, more often, 2 weeks after surgery. Runs continuously. - Voice change = the nerve is being stimulated (expected). - Complications: hoarseness (most common), cough, dyspnea, neck pain, dysphagia. - Avoid magnetic resonance imaging scans (MRIs), microwaves, shortwave radios, ultrasound diathermy. Patient & family teaching: Box 36.10Read in book - Know drug name, dose, timing, side effects, what to do if a dose is missed. - Never stop antiepileptic drugs (AEDs), even if seizures stop. - Keep blood-level appointments. No over-the-counter (OTC) drugs without asking. - Wear a medical alert bracelet or carry an ID card. - Family knows how to help during a seizure and when to call emergency medical services (EMS). - Follow state driving and machinery laws. - Avoid alcohol and excessive fatigue. Balanced diet, rest, stress reduction. Seizure diary. - Can't afford meds? Refer to social services / case manager. - Discrimination is illegal, but risky jobs (construction, heavy equipment, pilots) may need to change. Book · Mastery Q3 · Select all A hospitalized client has a tonic-clonic seizure. Which actions are most appropriate during the seizure? During: suction gently, remove hazards. Nothing goes in the mouth. Vitals come after. Benzos are for status or clusters, not every single seizure. Book · NGN Challenge 36.1 Case: 54-year-old had 3 tonic-clonic seizures (2–3 min each) in the past hour. Got intravenous (IV) lorazepam; fosphenytoin infusing; O₂ 2 L. Now back to baseline, A&O ×4, vitals normal. Review class: seizure priorities + meds Review class From the in-class exam review (Joline case study + NCLEX questions). - Tonic-clonic seizure, loses consciousness → priority: turn to the side (aspiration risk). If there's no trauma/fall in the story, you're not worried about spinal injury. - Status epilepticus = seizure that keeps going. Stop it with a benzodiazepine ending in -pam: diazepam or lorazepam. - Phenytoin / fosphenytoin (fosphenytoin more common) do NOT stop a seizure in progress. They prevent future seizures. Quick recall · tap to flip NCLEX A client is having a tonic-clonic seizure in bed. What should the nurse do first? Side-lying protects the airway. Never restrain, never put anything in the mouth, never leave. NCLEX A client has been seizing for 6 minutes. Priority action? Over 5 minutes = status epilepticus. Airway first. Nothing by mouth. NCLEX A client on an anti-seizure drug takes birth control pills. Best teaching? These drugs make the pill less effective. Never stop them suddenly, and no grapefruit. NCLEX Which finding in a client on long-term anti-seizure meds needs follow-up first? These drugs can cause depression and suicidal thoughts. Safety first. The 60-second version ## Infected brain covering = pressure + sepsis danger - Meningitis = inflamed meninges (the wrapping around brain and spinal cord). - Viral = more common, gets better in 7–10 days. Bacterial = emergency, can kill in 24 hrs. - Meningococcal (bacterial) → droplet precautions. - Diagnose with a lumbar puncture, but computed tomography (CT) first if signs of ↑intracranial pressure (ICP). - Top 3 checks: neuro, vital signs, circulation. The brain sits in a sealed jar. Swelling raises the pressure inside. Opening the bottom of the jar (lumbar puncture) can make the brain shift down. Check the pressure with a computed tomography (CT) before you open it. How it gets in A germ gets into the blood and crosses the blood-brain barrier. - Sources: brain or spine surgery, ear or sinus infection, flu or pneumonia. - Prevention = vaccines: flu, pneumonia, meningococcal. - Meningococcal vaccine: age 11–12, booster at 16. Viral vs. bacterial | | Viral | Bacterial (meningococcal) | | --- | --- | --- | | How common | More common | Less common | | How bad | Most recover in 7–10 days | Emergency. Can kill within 24 hrs | | Spread | — | Highly contagious; outbreaks in dorms, group homes | | Isolation | Standard | Droplet | Encephalitis = inflamed brain tissue itself. Same signs, but more long-term brain damage. Signs & symptoms - Nuchal rigidity: stiff, sore neck. - Severe headache, photophobia, nystagmus, pupil changes. - Altered mental status, seizures, ↑intracranial pressure (ICP), positive Babinski, sepsis. Fever may be missing. Why?\ 1\. Older adults run cooler, so 98.6°F might already be a fever for them.\ 2\. They're already on antibiotics for the first infection (like sinusitis). The drug didn't kill the germ, and it reached the brain. Babinski reflex How: stroke the bottom of the foot from the heel up to the toes. | Toes do… | Name | Adult meaning | | --- | --- | --- | | Curl down | Absent Babinski | Normal (what we want) | | Big toe up, others fan out | Positive Babinski | Problem in the brain or spinal cord | Exception: positive Babinski is normal under age 2. Their nervous system isn't mature yet. Lumbar puncture (spinal tap) Meningitis is diagnosed by testing cerebrospinal fluid (CSF). - Position: side-lying, knees to chest (fetal position). - Patient must stay very still (may need help holding or sedation). Danger: if there are signs of ↑intracranial pressure (ICP), letting CSF out fast can make pressure worse. computed tomography (CT) scan first. Cultures & antibiotics: the exception Normal rule: get cultures first, then antibiotics. Exception (signs of ↑intracranial pressure (ICP), no time for computed tomography (CT) + lumbar puncture (LP)): 1. Draw blood cultures immediately. 2. Start a broad-spectrum antibiotic right away. 3. Skip the cerebrospinal fluid (CSF) culture (LP too risky). 4. Germ identified → switch to a narrow-spectrum antibiotic. Top 3 nursing priorities 1. Neuro status. First sign of ↑intracranial pressure (ICP) = change in behavior (restless, irritable, "something's off"). Seizure precautions. 2. Vital signs: clues to rising ICP. 3. Circulation check: color, temperature, cap refill, pulses in hands and feet. Watch for bleeding (gums, urine, intravenous (IV) site). Why bleeding? Sepsis makes tons of tiny clots. They use up all the platelets and clotting factors, so none are left for normal clotting → bleeding. This is disseminated intravascular coagulation (DIC) (disseminated intravascular coagulation). Read in book Iggy Ch. 36, pp. 907–909 · crossed-out parts skipped What & how it enters (book)Read in book Infection of the pia mater and arachnoid mater. Usually bacterial or viral; also fungal or protozoal. Sterile meningitis can come from cancer, nonsteroidal anti-inflammatory drugs (NSAIDs), antibiotics, intravenous (IV) immunoglobulin. Ways in: bloodstream, or directly through penetrating trauma, brain/spine surgery, ruptured brain abscess. Basilar skull fracture: clear "runny nose" (rhinorrhea) or ear drainage (otorrhea) may actually be cerebrospinal fluid (CSF) → path for infection. Higher risk: head/neck infections (otitis media, sinusitis, tooth abscess, even tongue piercing); immunocompromised (no spleen, immunosuppressants, transplant, cancer); older adults. Can cause permanent cranial/spinal nerve damage and ↑intracranial pressure (ICP). Organisms & vaccinesRead in book Viral = "aseptic" meningitis (no organism grows in cerebrospinal fluid (CSF) culture): enterovirus, herpes simplex virus (HSV)-2, varicella zoster, mumps, human immunodeficiency virus (HIV). Bacterial: Streptococcus pneumoniae and Neisseria meningitidis (= meningococcal). Outbreaks: dorms, military barracks, crowded housing. Vaccine schedule (CDC): highest risk = ages 16–21. First meningococcal dose at 11–12, booster at 16. Adults: shared housing, travel, or no spleen. Booster OK as early as 8 weeks after first dose. Other vaccines that prevent meningitis: Hib, pneumococcal, mumps, varicella, meningococcal. Key features: Box 36.11Read in book - ↓level of consciousness (LOC), disorientation - Photophobia, nystagmus (jerky repetitive eye movements) - Motor normal early → later hemiparesis/hemiplegia - Cranial nerve problems: cranial nerve (CN) III, intravenous (IV), VI, VII, VIII - Short attention span, personality changes - Severe, unrelenting headache; myalgia; N/V; fever, chills; tachycardia - Red macular rash = meningococcal Nuchal rigidity, Kernig and Brudzinski signs show up in only a small percentage. Diagnostics (book)Read in book computed tomography (CT) before lumbar puncture (LP) for: age over 60, immunocompromised, or signs of ↑intracranial pressure (ICP). - LP delayed? Draw blood cultures (C&S) first. - Broad-spectrum antibiotic right after the LP (or right away if LP is delayed). - cerebrospinal fluid (CSF) tested for cell count, differential, protein, glucose, culture, Gram stain. - complete blood count (CBC): white blood cell count (WBC) well above normal. Electrolytes checked. - X-rays of chest, sinuses, mastoids (find the infection source). - CT/magnetic resonance imaging (MRI): ↑ICP, hydrocephalus, abscess. Treatment & isolationRead in book - Broad-spectrum antibiotic until culture and Gram stain return. - Bacterial: usually a 2-week intravenous (IV) antibiotic course. Start within 1–2 hours of the order. - Mannitol for ↑intracranial pressure (ICP); antiepileptic drugs (AEDs) for seizures. Droplet Precautions (in addition to Standard) for N. meningitidis and H. influenzae: private room · stay 3 feet away without a mask · patient wears a mask outside the room · teach visitors. All other meningitis: Standard Precautions. Nursing care: Box 36.12Read in book Most important nursing action: accurately monitor and document neuro status. Neuro checks + vital signs (VS) every 2–4 hours. - airway, breathing, circulation (ABCs) first. Cranial nerve checks. - Vascular check every 4 hrs, especially the hands: temp, color, pulses, nail cap refill. Missed compromise → gangrene → loss of the arm. - Strict I&O, prevent fluid overload; daily weight. - Quiet room, dim lights (photophobia). - Bed rest, head of bed (HOB) 30°. Reposition (pressure injuries); range of motion (ROM) every 4 hrs. - Watch for: ↑intracranial pressure (ICP), vascular problems, fluid/electrolyte imbalance, seizures, shock. Also septic shock, clotting disorders, acute respiratory distress syndrome (ARDS), septic arthritis. Book · NGN Challenge 36.2 Case: 21-year-old with suspected bacterial meningitis. Temp 101.6 → 102.4°F → 100.8°F. white blood cell count (WBC) 18,000. At 0600: A&O ×4, headache 8/10. At 0700: drowsy, oriented ×2, unsure of day and time, "very sleepy," headache 5/10. Review class: bacterial meningitis: order of actions Review class From the in-class exam review (Joline case study + NCLEX questions). 1. Isolation first (protect yourself and the team). Droplet precautions: regular surgical mask, private room. No negative-pressure room needed. 2. Insert an intravenous (IV) line (circulation; emergency meds). 3. Computed tomography (CT) of the head before the lumbar puncture: rule out ↑intracranial pressure (ICP). A lumbar puncture with high ICP pushes it even higher. 4. Broad-spectrum antibiotic right away while waiting on the culture and sensitivity (C&S). 5. Once the organism is identified → switch to a narrow-spectrum antibiotic. NCLEX mindset: even if the patient is blue, you don't skip your own protection. Quick recall · tap to flip NCLEX A client with suspected bacterial meningitis becomes newly restless and irritable. Priority? Behavior change is the earliest sign of ↑ICP. Sedation would hide the neuro exam. NCLEX A college student has meningococcal meningitis. Which precautions? Meningococcal spreads by droplets. Viral meningitis uses standard precautions. NCLEX Stroking an adult's sole makes the big toe go up and the toes fan out. This means: In adults, toes should curl down. Fanning up signals a brain or spinal cord problem. The 60-second version ## Not enough dopamine → movement gets shaky, stiff, and slow - Progressive brain disease that affects movement. - Signs = TRAP + low blood pressure (BP) when standing, drooling, peeing at night. - Main drug: carbidopa-levodopa (Sinemet). Take with carbs, not protein. - Biggest nursing job: fall prevention and nutrition. Acetylcholine is the gas pedal. Dopamine is the brake. In Parkinson's the brake wears out but the gas stays the same → shaky, jerky, hard-to-control movement. Signs: TRAP TTremor: "pill rolling" (thumb rubs finger) at rest. Handwriting gets tiny and squiggly. RRigidity: muscles can't relax → mask-like face, less blinking/smiling, trouble speaking, trouble swallowing, drooling. AAkinesia/bradykinesia: slow movement. Eating, writing, shaving get hard. PPostural instability: stooped, shuffling, freezing gait ("feet stuck to the floor") → falls. Automatic-body problems Dopamine also helps run the "fight or flight" system. Less dopamine → it underperforms: - Orthostatic hypotension: blood pressure (BP) drops on standing → dizzy → falls. - Drooling: less automatic swallowing. - Nocturia: peeing at night. Meds: carbidopa-levodopa (Sinemet) Your instructor said these are the most common Parkinson's meds and the only ones you need to know. Replaces the missing dopamine (the brake). - Nausea is common → take with food, but carbs, not protein (protein blocks absorption). - Long-term: dyskinesia (uncontrolled movements). - "On-off": symptoms controlled (on), then back (off), several times a day. Meds: dopamine agonists Copy dopamine. Side effects are less common but more serious → often not safe for older adults. - Impulse control problems: gambling, hypersexuality (dopamine = pleasure). - Mood changes. Tolerance, toxicity & drug holiday | Tolerance | Toxicity | | --- | --- | | Med just isn't working as well | Delirium (sudden confusion) | Delirium = sudden. Dementia = slow and long-term. Fix for both: lower the dose or frequency, change meds, or a drug holiday (off the med 1 week up to 10 days, then restart). Deep brain stimulation (DBS) When meds aren't enough. Approved for severe tremors. - Electrodes go into the brain; wires run under the skin to a device in the left chest (like a pacemaker). - Sends pulses that decrease involuntary movements and block tremors. - Not a cure. Disease still progresses. - Same precautions as a pacemaker: avoid electromagnetic fields and magnetic resonance imaging scans (MRIs). Nursing management (slides)Slides - Injury prevention (falls): muscle strengthening, stretching, flexibility, balance and coordination. - Exercise, range of motion (ROM), walking; self-care; sleep problems. - Communication and speech help; emotional support; support groups. - Nutrition: high protein, high calorie (unless liver or kidney disease) · soft diet, thickened liquids · weigh weekly · swallow evaluation. Watch the trap: high-protein diet for weight, but keep protein away from the Sinemet dose. Captions mishear: `Echinacea` = bradykinesia · `pastoral` = postural · `cinnamon` = Sinemet · `bacteria` = nocturia Read in book Iggy Ch. 36, pp. 894–899 · crossed-out parts skipped (stages box, monoamine oxidase (MAO)-B/catechol-O-methyltransferase (COMT) drugs, imaging, other surgeries) Patho & early signs (book)Read in book Primary (idiopathic) is most common. Secondary parkinsonism: brain tumors, some antipsychotics. Substantia nigra degenerates → less dopamine. Protein alpha-synuclein is thought to drive it. Symptoms appear only after a big dopamine drop (book: 70–80%). Non-motor signs can appear YEARS before TRAP: constipation, soft voice, micrographia (tiny handwriting), loss of smell, sexual dysfunction, sleep problems. - traumatic brain injury (TBI) raises Parkinson's disease (PD) risk → teach contact-sport athletes to wear helmets. - Veterans: TBI, Agent Orange exposure. - Lewy bodies (abnormal proteins) → some get Lewy body dementia. - About 50% more men than women. Assessment (book)Read in book - Rigidity = resistance to passive movement; present early. - Stage 4: needs a walker and help with activities of daily living (ADLs). Stage 5: trouble chewing and swallowing. - Late: dementia, psychosis (delusions, paranoia, hallucinations), depression, anxiety, apathy. - Autonomic: excessive sweating, orthostatic hypotension. - Speech: soft, slurred, monotone, halting, or rapid. - Bladder: incontinence or trouble urinating. Bowel: constipation. No specific test. Diagnosis is clinical, after ruling out other neuro diseases. Priority problems: 1) ↓mobility (self-care deficit) · 2) impaired cognition. Priority of care: keep mobility and activities of daily living (ADL) independence as long as possible. Box 36.7: best-practice careRead in book - Give patients extra time to answer and to do activities of daily living (ADLs); help only as needed. - Give meds on time, on their individual schedule (steady drug levels). - Fall Precautions; physical therapy (PT)/occupational therapy (OT). - Prevent immobility complications: constipation, pressure injuries, contractures. - Schedule activities late morning or at their best time of day. - Teach to speak slowly and clearly; communication board; refer to speech-language pathologist (SLP). - Monitor swallowing and intake; high-protein, high-calorie foods. - Focus on strengths (self-esteem). Assess depression, anxiety, cognition, insomnia. Drug details (book)Read in book Dopamine agonists (apomorphine, pramipexole, ropinirole; rotigotine patch): best in the first 3–5 years; fewer dyskinesias and less "wearing off." Agonist Drug Alert: orthostatic hypotension, hallucinations, sleepiness → no driving or heavy machinery · rise slowly · shouldn't be prescribed to older adults. Carbidopa/levodopa: nearly everyone takes it eventually. Cheaper and better for motor function than agonists. Comes as immediate-release (IR), controlled-release (CR), enteral infusion, and an inhaled form for "off" periods. Safinamide is an add-on. Book says: give levodopa before meals for better absorption. Lecture says: if it causes nausea, take with carbs, not protein. Both point the same way: keep protein away from the dose. Toxicity = delirium, hallucinations, less effect. Compare to the pre-drug baseline. Tolerance = effects wear off sooner. Drug holiday lasts up to 10 days; monitor and document Parkinson's disease (PD) symptoms during it. Symptom helpers: baclofen (spasms), sublingual atropine (drooling), zolpidem (insomnia). Medical cannabis: stay nonjudgmental. Freezing gait, sleep, eating & speechRead in book Freezing gait tricks: step sideways, then forward · shift weight side to side, then step · picture an object on the floor to step over. Yoga and tai chi help early. range of motion (ROM), stretching, out of bed. Sleep: poor nights + short naps they may not notice → risk of falling asleep while driving. - speech-language pathologist (SLP) swallowing evaluation. Soft diet, thick cold fluids (milkshakes), small frequent meals, thickener (Thick-It). - Elevate the head to prevent aspiration. Weigh weekly. - Speech: slow, deep breaths, exaggerate words; reduce background noise; listener watches lips. Cognition, home care & deep brain stimulation (DBS) (book)Read in book - About 50% develop cognitive problems. Depression is common (venlafaxine may be used). - Don't force social events; emphasize strengths. - Teach to report dizziness, falls, delirium, hallucinations. - Constipation: fluids, high fiber, bowel program. Sleep hygiene: no alcohol or caffeine, dark room. - Impulse control problems: remind family the patient can't control them. Watch for caregiver strain. - Late disease → palliative or hospice care. - DBS: reduces the need for levodopa; usually not offered while meds still work. Book · Mastery Q2 An ambulatory client was recently diagnosed with early Parkinson's. What finding does the nurse expect? Resting tremor is an early sign. Dementia and swallowing problems come late. Book · NCLEX Challenge 36.3 · Select all Client prescribed ropinirole. Which teaching statements should the nurse include? Ropinirole is a dopamine agonist: orthostatic hypotension, sleepiness, possible dyskinesias. The patch is rotigotine, and the food rule is for monoamine oxidase inhibitors (MAOIs). Review class: Parkinson's meds + earliest sign Review class From the in-class exam review (Joline case study + NCLEX questions). - Earliest (initial) sign: tremor. All the classic signs are Parkinson's, but tremor usually comes first. - Ropinirole = dopamine agonist (mimics dopamine). Caution in older adults: orthostatic hypotension and drowsiness → falls. - Carbidopa-levodopa (Sinemet): levodopa is turned into dopamine. Causes nausea → take with food, but NOT protein (protein blocks absorption: no peanut butter, eggs). Quick recall · tap to flip NCLEX Which breakfast is best with the morning carbidopa-levodopa dose? Protein blocks levodopa. Carbs help nausea without blocking it. NCLEX Top safety concern for a client with Parkinson's? Low BP on standing + poor balance = high fall risk. NCLEX A family says their dad on a dopamine agonist is suddenly gambling a lot. The nurse knows: Dopamine drives pleasure and reward, so agonists can cause impulse control problems. The 60-second version ## Inherited disease: dementia + "dancing" movements - Hereditary. Symptoms start at age 30–50. - Brain cells die → progressive dementia + chorea. - Child of a parent with it: 50/50 chance. - No cure. Control symptoms, prevent complications. "Chorea" is Greek for dance (like "choreography"). Picture fast, jerky dance moves the person can't stop. Chorea & treatment Chorea = rapid, jerky movements of the arms, legs, and face. The term is used only for Huntington's. - The movements have no purpose. - The patient can't stop or control them. Care is the same as for anyone with a movement or memory disorder (Parkinson's, Alzheimer's): - Assistive devices; physical therapy (PT), occupational therapy (OT), speech therapy. - Keep familiar routines. Break tasks into small steps. - Avoid open-ended questions (ask yes/no or simple choices). - To-do lists and calendars. Genetics & testing - Parent has it → each child has a 50% chance. - Child doesn't carry the gene → won't get it and can't pass it on. - A test can show the gene. Hard question: is it better to know? - Not done under age 18: they may feel pressured and aren't mature enough for the results. - Genetic counseling is very important for the children (ethical dilemma). Quick recall · tap to flip NCLEX A 16-year-old whose father has Huntington's asks to be tested. Best response? No testing under 18. Risk is 50%, and it doesn't skip generations. NCLEX Which communication works best for a client with Huntington's? Avoid open-ended questions. Simple yes/no choices work better with cognitive decline. The 60-second version ## multiple sclerosis (MS): the immune system strips the wire coating - Autoimmune. Damages myelin in the brain and spinal cord → signals weak or blocked. - Comes in waves: flare-ups and remissions. - Top symptoms: fatigue, mobility problems, vision changes. - Avoid heat, stress, fatigue. No hot showers, no hard exercise. - amyotrophic lateral sclerosis (ALS): movement only. Mind and senses stay intact. Myelin is the plastic coating on a phone charger cord. Strip patches off and the signal flickers or cuts out. What multiple sclerosis (MS) is - Myelin cushions and protects nerves and helps signals travel between brain, cord, and body. - Demyelination → signals are weaker, or don't get through. - Progresses at different speeds in different people. Why diagnosis takes so long (frustrating for patient and family): - No single test confirms it. - Symptoms look like other neuro problems, which must be ruled out. - Symptoms go away for a while, so people don't seek care. Signs & symptoms - Overwhelming fatigue. - Weak, stiff legs: hard to move them, hesitant → fall risk. - Vision (optic nerve): nystagmus, double vision, blurry vision. - Dysarthria: slurred or scanning speech (long pauses between words; can sound like stuttering). - Spasticity, numbness/tingling, intention tremor (shakes when reaching), poor coordination, positive Babinski. - Trouble swallowing; bowel, bladder, and sexual problems; memory and focus problems. Don't mix up tremors: Parkinson's = shakes at rest. multiple sclerosis (MS) = shakes when moving (intention). Nursing care Prevent flare-ups: avoid fatigue, stress, temperature extremes (hot showers). Keep them independent: - Stay organized; keep often-used items within reach (saves energy). - Speech therapy for swallowing trouble. Eye patch for double vision. - Strength and stretching exercises (PT/occupational therapy (OT)) for balance and coordination. - No rigorous exercise: raises body temp → more fatigue, less movement. Main goal = symptom control. multiple sclerosis (MS) meds (only 2 to know) No cure. Immunomodulators slow the disease and make attacks fewer and milder. Your instructor said know only these: | Drug | Key points | | --- | --- | | Interferon beta | Shot under the skin (every other day or weekly). Infection risk, bone marrow suppression, flu-like symptoms. | | Glatiramer | Shot under the skin. Fewer side effects. | amyotrophic lateral sclerosis (ALS) (Lou Gehrig's disease) - Motor neurons die → weakness, muscle wasting, stiffness → paralysis. Cause unknown. - Only movement is affected. They can still see, hear, and feel, and thinking stays intact. - Starts in one area, then spreads. Lose the ability to talk, swallow, and breathe. - Signs: tired while talking, tongue shrinking, slurred speech, trouble swallowing, face twitching (fasciculations). - Death usually within 3 years, from respiratory failure. - No cure. Meds treat pain, spasms, extra secretions, sleep problems. Communication aids. - May need a feeding tube and ventilator. Get advance directives early. Hospice supports the family. Read in book Iggy Ch. 37, pp. 913–920 · crossed-out parts left out (MS types except relapsing-remitting multiple sclerosis (RRMS), cerebrospinal fluid (CSF)/evoked potentials, other MS drugs) What happens in multiple sclerosis (MS)Read in book - Cause: immune, genetic, and/or infectious factors. - Demyelination slows or stops nerve signals → patchy plaques in white matter. - Early on, myelin repairs itself and symptoms fade. Over time, damage builds and muscle atrophy sets in. - Often hits the optic nerves, spinal tracts, brainstem, and the area around the ventricles. - A leading cause of neuro disability in young and middle-age adults. Types of multiple sclerosis (MS)Read in book | Type | Pattern | | --- | --- | | relapsing-remitting multiple sclerosis (RRMS) (relapsing-remitting) | Most common. Flares over weeks to months, then back to baseline. | RRMS is a roller coaster that returns to the station. Who gets itRead in book - Women 2–3× more than men (some studies say up to 4×). - Ages 20–50. About 1 million people in the US. - More common in colder climates (Great Lakes, Pacific Northwest). - A first-degree relative with multiple sclerosis (MS) raises risk. multiple sclerosis (MS) vs. amyotrophic lateral sclerosis (ALS) (Table 37.1)Read in book | | MS | ALS | | --- | --- | --- | | Cause | Immune attack on myelin; remissions + flares | Unknown (genetic + environmental); progressive muscle wasting → respiratory paralysis | | Who | Common; women 2× men; ages 20–50 | Uncommon; men more; ages 40–60 | | Signs | Fatigue, spasticity, diplopia, scotomas, nystagmus, paresthesias, bladder problems, intention tremor | Fatigue, muscle atrophy (incl. tongue), twitching of face and tongue, dysarthria, dysphagia | | Outlook | Many disease-modifying drugs | 100% fatal; no cure. Supportive + palliative care | Signs & symptoms (Box 37.1)Read in book History: early symptoms are vague and come and go, so diagnosis often takes years. Ask about vision, motor, and sensory changes. Ask what makes it worse: fatigue, stress, temperature extremes, hot showers or baths. Common: - Muscle weakness and spasticity; flexor spasms - Fatigue, worse with heat - Paresthesia (numbness, tingling) - Vision: diplopia (double vision), nystagmus, ↓acuity, scotomas (blind spots) - Bowel and bladder problems (flaccid or spastic); sexual dysfunction - Cognitive changes: memory, judgment, problem solving - Depression, emotional changes - "MS hug" (dysesthesia): squeezing feeling around the torso. Often an early sign. - Trouble walking, dysmetria (can't control movement range), vertigo, pain, itching Less common: intention tremor (shaking when reaching for something), hypalgesia, dysarthria, dysphagia, hearing loss, tinnitus, loss of taste, seizures. Don't mix up the tremors: Parkinson's = resting tremor (pill-rolling at rest). multiple sclerosis (MS) = intention tremor (during movement). PsychosocialRead in book - Long road to diagnosis → anger and frustration. Let them vent. - After diagnosis: anxiety. Later: apathy, emotional lability. - Secondary depression is the most common mental health problem in multiple sclerosis (MS). - Some are euphoric (from the disease or the drugs). - Cognition changes are usually late: memory, concentration, calculation, judgment. - Fatigue affects sexuality. Women: less sensation and orgasm. Men: erection and ejaculation problems. DiagnosisRead in book No single test. Results are put together. - magnetic resonance imaging (MRI) of brain and spinal cord showing plaques in at least 2 areas = diagnostic. Drug therapyRead in book Goal: slow the disease and reduce flares. Most drugs suppress immunity → infection risk. Teach: avoid crowds and sick people, wash hands. | Drug | Key nursing point | | --- | --- | | Interferon beta; glatiramer | Subcutaneous self-injections. Rotate sites. Flulike symptoms → acetaminophen/ibuprofen. Bone marrow suppression → report infection. | Symptom drugs: baclofen or tizanidine (spasticity; severe → intrathecal baclofen pump) · carbamazepine or tricyclic antidepressants (TCAs) (paresthesia) · propranolol, clonazepam (ataxia). Medical cannabis may ease pain and stiffness. Stem cell therapy is being studied. multiple sclerosis (MS) drugs are very expensive (health equity issue). Nursing care: mobility, vision, cognitionRead in book - physical therapy (PT)/occupational therapy (OT): range of motion (ROM), stretching, strengthening. - Avoid things that raise body temp (worsen fatigue and vision). - Home safety: remove rugs and clutter; adapt for a wheelchair. Plan rest periods. - Dysarthria / dysphagia → speech-language pathologist (SLP); thickened liquids if needed; watch for aspiration. - Diplopia: eye patch, switched eye to eye every few hours. - Peripheral vision loss: teach scanning (turn the head side to side). - Cognition: single-date calendar, written lists, keep items in familiar places, phone reminders. Going homeRead in book Teach to avoid triggers: overexertion, stress, temperature extremes (fever, hot baths, saunas, hot tubs, overheating, getting chilled), humidity, people with infections. - Energy conservation: balance rest and activity. - Know every med: dose, time, route, side effects. - Personality changes: family can agree on a signal for inappropriate behavior. - Sexual dysfunction: phosphodiesterase (PDE)-5 inhibitors (sildenafil) for men; refer to counseling or urology. - Refer to the National multiple sclerosis (MS) Society. Book · NCLEX Challenge · Select all A client was recently diagnosed with MS. Which common findings does the nurse expect? Weakness, vision changes, spasticity, and fatigue are common early. Cognitive changes come later; hallucinations aren't typical. Book · Mastery Q2 · Select all A client will start interferon beta-1a. What should the nurse teach? Interferon = immune suppression, subcutaneous injections, flulike aches. The pulse and confusion options belong to other MS drugs that are crossed out of your reading. Quick recall · tap to flip NCLEX Which MS client statement needs more teaching? Heat worsens MS symptoms. NCLEX A client starting interferon beta asks what to watch for. Best answer? Interferon suppresses immunity and often causes flu-like symptoms. NCLEX The family of a client with late ALS asks if he still understands them. Best response? ALS spares thinking and senses. The 60-second version ## Spinal cord injury: protect the neck, watch the blood pressure (BP), find the trigger - Trauma = safety first, then airway, breathing, circulation, disability, exposure (ABCDE), then head-to-toe. - Open the airway with a jaw thrust (protects the neck). - Neurogenic shock = low BP + LOW heart rate. - Autonomic dysreflexia = sudden HIGH BP → sit up, check the bladder. The spinal cord is the phone line between brain and body. Cut it, and messages can't get through either way. Below the cut, the body can panic, and the brain's "calm down" message never arrives. Basics - Top causes: car crashes and falls. About 80% are men. - Complete = no messages below the injury. Incomplete = some movement or feeling left. - Primary injury = the trauma: bending forward too far (hyperflexion), back too far (hyperextension), crushed downward (axial loading), twisted, or stabbed/shot. - Secondary injury = makes it worse: bruising, swelling presses on the cord → low blood flow; bleeding; neurogenic shock. Trauma steps: safety, A & B 1. Safety first: scene and team. personal protective equipment (PPE) on (gloves, gown, eye protection, mask, cap, shoe covers). 2. Primary survey (ABCDE): find and fix life threats. 3. Secondary survey: head-to-toe exam. A = Airway. Suction; check for face injuries blocking it. Protect the neck: jaw thrust, not head tilt. Keep the neck straight and in line. "C3, 4, 5 keeps the diaphragm alive." These nerves run the breathing muscle. A high neck injury can stop breathing. Glasgow Coma Scale (GCS) under 8 → intubate. B = Breathing. Breathing isn't enough; it must be effective. - Weak effort (gasping, respiratory rate (RR) about 6) → bag-valve mask. Oxygen alone won't help. - Breathing well on their own → non-rebreather mask. - Check both sides of the chest rise equally (collapsed lung?). C, D & E C = Circulation. - Outside bleeding: direct pressure, pack the wound, tourniquet above it. Log roll to check the back. - Inside bleeding shows as shock: low blood pressure (BP), fast heart rate (HR), weak pulse. Check the belly and pelvis. - Two big intravenous lines (IVs) (16-gauge) in the inner elbows. - No BP cuff? Feel for pulses. Systolic is at least: radial 80 · femoral 70 · carotid 60. Exception: massive uncontrolled bleeding → order becomes C-A-B. Stop the bleeding first. D = Disability (quick neuro): Glasgow Coma Scale (GCS), pupils, can they feel and move all 4 limbs? E = Exposure. Remove clothing to see everything. - Burns: clothing can melt into skin. - Save evidence (weapons, rape kits) for court. - Prevent hypothermia: blankets, warm room, warm intravenous (IV) fluids. Cover for dignity. Secondary survey: head-to-toe exam, splints, dressings, nasogastric (NG) or orogastric (OG) tube (empties stomach), urinary catheter (monitors kidneys). Neurogenic shock vs. spinal shock | | Neurogenic shock | Spinal shock | | --- | --- | --- | | What | Lost "fight or flight" tone → vessels go slack | Cord's reaction to injury and swelling (not a true shock) | | Signs | Low blood pressure (BP) (SBP \<90 or mean arterial pressure (MAP) \<65) + LOW heart rate, low temp, abnormal rhythms | Temporary loss of movement, feeling, reflexes, and automatic functions below the injury; limp paralysis; bowel stops (paralytic ileus) | | Care | Emergency! Fluids, vasopressors | Usually gone within 48 hrs as swelling goes down | The trick: every other shock has a fast heart rate. Neurogenic shock has a slow one. Positioning, collars & halo - Constant, detailed movement and feeling checks catch problems early. - Keep the body aligned: log roll, turning sheet, slider board. - Thoracic or lumbar injury: may wear a brace out of bed. - Possible neck injury: hard cervical collar stays on until a specific provider order says remove. - Cord being squeezed → surgery: remove blood clot, bone pieces, or object; spinal fusion. Halo device (pins in skull, ring, vest), worn 8–12 weeks: - Never tighten or loosen the screws. Never pull on it to move them. - Wrench taped to the vest for emergencies (CPR). - Pin care: watch for redness, drainage; clean them. Prevents skull bone infection. - Check skin under the vest. Itchy? Nothing goes inside (like a cast). - Drinks through a straw. Autonomic dysreflexia: emergency A huge, uncontrolled "fight or flight" surge. Usually after the acute phase (often first seen 3–6 months after injury). Cause: something irritating below the injury. Most often a full bladder or constipation. Also pressure sores, pain, a wrinkled sheet. | Sign | Why | | --- | --- | | Sudden severe high blood pressure (BP) | Vessels below clamp down → risk of stroke | | Slow heart rate | Body tries to lower BP | | Severe headache, vision changes | High BP | | Sweating + flushing ABOVE injury | Vessels above open up | | Cool, pale skin BELOW injury | Vessels below stay tight | 1. Sit them up (High Fowler's) right away. 2. Find and fix the cause. Kinked Foley? Feel for a full bladder. No catheter → insert one. Check for constipation. 3. Call the provider. Nifedipine or a nitrate as ordered. 4. Check BP every 2–5 minutes. Body systems after spinal cord injury (SCI) | System | Watch for / do | | --- | --- | | Lungs | Secretions build up → assisted coughing, incentive spirometer | | Heart | Low blood pressure (BP), low heart rate (HR), low temp, abnormal rhythms, dizzy when sitting up, autonomic dysreflexia, blood clots (compression devices, low molecular weight heparin) | | Gut | Belly bleeding, paralytic ileus, nutrition | | Bowel/bladder | Retention or incontinence; constipation (fluids, fiber, stool softeners); may learn self-cath | | Muscles/bones | Muscle wasting, spasticity → contractures; osteoporosis → fractures | | Skin | Turn every 1–2 hrs in bed. In a wheelchair, shift weight more than every hour (wheelchair push-ups, chair pad) | | Feelings | Anger (don't want to depend on others), depression. Check the home for safety and equipment. | Read in book Iggy Ch. 10 (trauma), pp. 208–210 Mechanism of injury (MOI)Read in book | Type | Examples | | --- | --- | | Blunt | Car crash, fall, assault (fists, kicks, bat), blast effect from a bomb | | Acceleration-deceleration (a blunt type) | High-speed crash, fall from a height → tearing, shearing, compression of tissues | | Penetrating | Knives, ice picks, gunshot wounds (GSW), shrapnel, falling onto a sharp object | A GSW to the chest or abdomen or a stab wound to the neck automatically calls the trauma team. Safety & primary survey (book)Read in book - Scene safety first, in the field and the emergency department (ED). Standard Precautions every time. - personal protective equipment (PPE): impervious gown, gloves, eye protection, facemask, surgical cap; shoe covers if heavy blood loss is expected. - Resuscitation happens at the same time as the survey. Fix airway, breathing, circulation, disability, exposure (ABCDE) problems before lower priorities like splints and dressings. Airway Critical Rescue: minutes without oxygen → anoxic brain injury. Clear the airway (suction or by hand), keep the neck neutral and in line, use a jaw thrust, give O₂. - Breathing on own → non-rebreather. Needs help → bag-valve mask (BVM) with 100% O₂. - Glasgow Coma Scale (GCS) 3–8 → endotracheal tube + ventilator. - Breathing check: breath sounds, effort, chest expansion, chest trauma. Circulation: - Firm direct pressure with thick dry dressing first. Tourniquet if pressure fails. Wound packing, hemostatic dressings. - Suspect internal bleeding in any shock state. - Hypotension is a late sign: the body's compensation is already used up. - intravenous lines (IVs): two 16-gauge antecubital; central line or intraosseous if veins can't be reached. - Fluids: lactated Ringer's or 0.9% normal saline (NS); hypertonic saline for head trauma. Warm all fluids and blood. - Blood: packed red blood cells (PRBCs), fresh frozen plasma (FFP), platelets, or whole blood. But the priority is always to stop the bleeding. Disability: AVPU = Alert, responds to Voice, responds to Pain, Unresponsive. GCS 3 (totally unresponsive) to 15 (normal). Low blood sugar, hypoxia, drugs, or alcohol can lower level of consciousness (LOC). Reassess often. Exposure: cut clothing off with scissors (fast access, avoid moving injured limbs, burned fabric stuck to skin). Preserve evidence (clothing, weapons, bullets, drugs) for rape, abuse, assault, homicide, overdose. Nurses may testify in court. Hypothermia = 96.8°F (36°C) or lower. Secondary survey & after (book)Read in book - Gastric tube (prevent vomiting and aspiration), urinary catheter (urine output), diagnostic tests, head-to-toe exam, splints, temporary dressings. - Disposition: straight to operating room (OR) or interventional radiology, admit, or transfer to a trauma center. - Then assess psychosocial needs: social services, rehab, pastoral care, mental health, substance use counseling. Include the family. Book · NCLEX Challenge 10.3 Which mechanism of injury does the nurse document for a client with one gunshot entry point and two stab wounds? Bullets and knives both pierce the body = penetrating trauma. Read in book Iggy Ch. 37, pp. 920–929 · crossed-out parts left out (neuro level/dermatomes, clonidine) Types & mechanisms of injuryRead in book Complete spinal cord injury (SCI) = no function below the injury. Incomplete = some function left (more common). | Mechanism | Example | | --- | --- | | Hyperflexion | Head snaps forward: head-on crash, diving | | Hyperextension | Head snaps back: rear-end crash, fall hitting the chin | | Axial loading | Vertical compression: diving, landing on buttocks or feet | | Excessive rotation | Head turned past normal range | | Penetrating | Knife (low speed) or gunshot (high speed) | Secondary injury (worsens the first): hemorrhage, ischemia, hypovolemia, low perfusion from neurogenic shock, swelling. Top causes of death: pneumonia and septicemia. Leading cause: trauma (more than 1/3 vehicle crashes); falls in older adults; violence; sports. Prevention: helmets and padding, seat belts, no impaired driving, water at least 9 feet deep before diving. Assessment termsRead in book | Term | Meaning | Injury level | | --- | --- | --- | | Tetraplegia (quadriplegia) | Paralysis of all 4 limbs | Cervical / upper thoracic | | Quadriparesis | Weakness of all 4 limbs | | | Paraplegia | Paralysis of legs only | Lower thoracic / lumbosacral | | Paraparesis | Weakness of legs only | | - Reflexes: biceps C5, triceps C7, patella L3, ankle S1. Absent during spinal shock. Autonomic dysreflexia: book detailsRead in book Box 37.2 key features: - Sudden big rise in blood pressure (BP) + bradycardia - Profuse sweating above the injury (face, neck, shoulders) - Flushing above the injury; goose bumps - Blurred vision, spots in the visual field - Nasal congestion - Severe throbbing headache - Feeling of apprehension Triggers: bladder distention, urinary tract infection (UTI), scrotal compression, constipation/impaction, hemorrhoids, pain, tight clothing, hard or sharp objects, temperature changes. Box 37.3: what to do 1. Sit them up (first priority). 2. Check the bladder: retention, catheter kinks. No catheter → check for distention and catheterize (anesthetic ointment on the tip). 3. Check for UTI or bladder stones. 4. Check for fecal impaction using anesthetic ointment. 5. Check skin for pressure injuries. 6. BP every 10–15 minutes. 7. Nifedipine or a nitrate as ordered. Lecture said BP every 2–5 min; the book says 10–15 min. Go with your instructor on exams, but know both. Airway & breathing (book)Read in book Airway is the priority for cervical spinal cord injury (SCI). Injuries at or above T6: risk of respiratory distress and pulmonary embolism (PE) in the first 5 days. - Breath sounds every 2–4 hrs the first few days. Act if oxygen saturation (SpO₂) drops below 95%. - Incentive spirometer; suction as needed. - Cough assist ("quad cough"): hands on the upper abdomen below the ribs; push inward and upward as the patient coughs. Neurogenic shock: book detailsRead in book Usually within 24 hrs, in injuries above T6. Critical Rescue (check at least hourly): warm, flushed skin (temp dysregulation) · symptomatic bradycardia · ↓level of consciousness (LOC) · ↓urine output · systolic blood pressure (SBP) \<90 or mean arterial pressure (MAP) \<65 → Rapid Response. - intravenous (IV) and oral fluids. Dextran (plasma expander). - Atropine if heart rate (HR) drops below 50–60. - Severe hypotension: IV vasopressors (phenylephrine, dopamine). Collar, surgery & halo (book)Read in book - Hard collar (Miami J, Philadelphia) until an order says remove. Pad pressure points, especially the back of the head. - Keep alignment; log roll. - After spinal fusion: neuro checks + vital signs (VS) every hour for 4–6 hrs, then every 4 hrs. - Thoracic/lumbar fusion: Harrington rods, molded plastic brace. Halo: 4 pins into the skull, worn 6–12 weeks (lecture said 8–12). Halo Action Alert: never move the patient by the halo · never adjust screws · one finger should fit between the jacket and skin · wrench taped to the vest · nothing sharp under the vest · pin care per policy. Report fever or pus from pins. Serious complications: osteomyelitis of the skull, subdural abscess. Meds for spinal cord injury (SCI)Read in book | Drug | Why | | --- | --- | | Pantoprazole (PPI) | Prevent stress ulcers | | Anticoagulant (LMWH) | Prevent venous thromboembolism (VTE) | | Bulk laxatives, stool softeners | Prevent constipation | | Celecoxib | Prevent heterotopic ossification (↑myocardial infarction (MI) and stroke risk) | | Calcium, bisphosphonates | Prevent osteoporosis | | Intrathecal baclofen (ITB) | Spasticity. Sedation, fatigue, headache, hypotension. Never stop suddenly → seizures, hallucinations. | Long-term complicationsRead in book - Paralytic ileus within 72 hrs; check bowel sounds. Stress ulcers. - Heterotopic ossification (HO): bony overgrowth into muscle. Not visible on x-ray for several weeks. - Pressure injuries, venous thromboembolism (VTE), osteoporosis → fractures, contractures (splints, range of motion (ROM)). - Orthostatic hypotension: change position slowly. - Transfers: paraplegic patients often transfer alone; tetraplegic may use a sliding board. | Lesion | Bowel/bladder | Care | | --- | --- | --- | | Upper motor neuron (cervical, high thoracic) | Spastic; reflex emptying still works | Bladder/bowel training; rectal suppositories | | Lower motor neuron (lower thoracic, lumbosacral) | Flaccid; no reflex | Intermittent catheterization; manual disimpaction | All: 1.5–2 L fluid a day + stool softeners. Psychosocial, sexuality & rehabRead in book - Often young men; may feel guilt (diving, racing). Many veterans (blast injuries). - Be realistic but offer hope. - Men with injuries above T6 may have reflex erections. A vasodilator before sex can prevent autonomic dysreflexia (AD). - Women can still become pregnant. - Rehab goal: live independently. Functional electrical stimulation (FES), exoskeletons. - Older adults with spinal cord injury (SCI): vaccines (respiratory infections are the top cause of death), osteoporosis prevention, skin care. Book · NCLEX Challenge A client with a recent T1 spinal cord injury (SCI) is flushed and sweating on the face and neck and reports "seeing spots." Which action first? Autonomic dysreflexia. Sitting up lowers blood pressure (BP) immediately. Then find the cause. Book · NCLEX Challenge 37.3 A client with SCI is in a halo fixator with vest. Which action is most important for safety? The wrench lets staff remove the vest fast for cardiopulmonary resuscitation (CPR). That's life-saving; the others are routine care. Book · Mastery Q1 A client with a C6 fracture just got a halo device. Which statement needs immediate follow-up? A new change in sensation moving upward = possible worsening cord injury. Numb feet were already there. Book · NGN Challenge 37.1 (C7 SCI, halo + vest) Case: 21-year-old, C7 SCI. At 1435: new throbbing frontal headache, blurred vision, very sleepy, face and neck flushed with sweating. T 99°F, heart rate (HR) 58, BP 184/95, oxygen saturation (SpO₂) 95%. Foley draining. At 1450: BP 192/98, headache 8/10. Review class: spinal shock, autonomic dysreflexia, trauma priority Review class From the in-class exam review (Joline case study + NCLEX questions). - Spinal shock: swelling right after the injury knocks out movement, feeling, and reflexes. It does not mean permanent paralysis. The injury can't be classified until spinal shock resolves (about 48 hours). - Spinal shock is over when things come back: they can urinate, reflexes return, they feel an itch or pain, they can move. - Autonomic dysreflexia: blood pressure shoots up + pounding headache. Caused by any irritating stimulus. Even a fan's cool breeze can trigger it. Find and remove the cause. - Trauma (Ch. 10 pages): normally airway, breathing, circulation, disability, exposure (ABCDE), but massive uncontrolled external bleeding comes first. No airway will help if they bleed out. Exception to the rule. Quick recall · tap to flip NCLEX A client with a T4 injury suddenly has BP 210/110, HR 48, a pounding headache, and a flushed face. First action? Autonomic dysreflexia. Sitting up lowers BP right away. Then check the bladder. NCLEX Which vital signs suggest neurogenic shock? Low BP with a LOW heart rate. Low BP + fast HR points to bleeding (hypovolemic shock). NCLEX A trauma client is gasping with a respiratory rate of 6. Priority? Weak breathing needs breaths given. Oxygen alone won't help. NCLEX A client in a halo vest says the skin under it itches. Best response? Nothing inside the vest. Never touch the screws or pull on the frame. The 60-second version ## Back pain: mostly a squished disc pressing a nerve - Neck and low back get hurt most (most flexible parts). - #1 cause of workplace injury. Protect your own back! - Comfort: Williams position, heat or ice, nonsteroidal anti-inflammatory drugs (NSAIDs). - After back surgery: cerebrospinal fluid (CSF) leak = lower head of bed (HOB), call. Must void before going home. - After neck surgery: airway first. A disc is a jelly donut between two bones. Squeeze it wrong and the jelly (nucleus pulposus) leaks out and presses on the nerve next to it. Protect your own back - Bend at the knees, not the back. - Raise the bed when repositioning a patient or giving a 2–3 minute intravenous (IV) push. - Good posture, proper shoes, weight control, ergonomics. - Use ceiling lifts and get help. No equipment? Advocate for it. Disc problems & nerve pain - Disc's jelly center = shock absorber. - Bulging disc = pushes out. Herniated disc = much worse, the wall breaks open. - Pressure on a nerve → burning or stabbing pain, spasms, numbness, tingling. - Low back → pain down the leg (sciatic nerve). Neck → pain down the arm. - Big herniation can press on the spinal cord → leg/arm weakness, bladder or bowel problems. - Spinal stenosis = narrowed spinal canal (from a disc, arthritis, infection, trauma, swelling). Tests | Test | Shows | | --- | --- | | magnetic resonance imaging (MRI) | Cord, bones, discs, and nerve root compression | | electromyography (EMG) | Needle in the muscle checks its electrical activity → nerve damage | | Nerve conduction study | How fast nerves send signals | Comfort & meds - Williams position: semi-Fowler's with a pillow under the knees. A recliner works too. - Firm mattress. Change positions often. - Moist heat or ice: 20–30 min, 4 times a day (whichever works for them). - physical therapy (PT), weight control, massage, chiropractor, acupuncture, transcutaneous electrical nerve stimulation (TENS) unit. | Med | Know this | | --- | --- | | nonsteroidal anti-inflammatory drugs (NSAIDs) (first choice) | Block prostaglandins (inflammation). Side effect: gastrointestinal (GI) upset. Adverse: bleeding. | | Muscle relaxants (baclofen, cyclobenzaprine) | Drowsiness, fatigue | | Gabapentin | Anti-seizure drug used for nerve pain | | Tramadol (Ultram) | If an opioid is needed: least potent, low dependency | | Epidural injection | Steroid + numbing med | Surgery | Minimally invasive | Open | | --- | --- | | Scope removes the piece pressing the nerve. Less pain and blood loss. Home same or next day. Walk daily. | Bigger incision. Used when the spinal cord is compressed. | - Discectomy = remove disc. Laminectomy = remove part of a vertebra. - Spine unstable → spinal fusion, often with bone from the hip → 2 painful sites that can get infected. After open back surgery - Vitals + neuro checks every hour for 4–6 hrs, then every 4 hrs. - Watch for fever, low blood pressure (BP), fast heart rate (HR). cerebrospinal fluid (CSF) leak: clear drainage, a "halo" ring on the dressing, bulging at the incision, or a sudden headache → lower the head of the bed and call the provider. - Check for a hematoma. Check the hip donor site. - Patient must void before discharge. - Turn as a unit (log roll). No twisting. No overhead trapeze. Neck (cervical) surgery - Front of the neck (anterior) is most common. Back (posterior) = more pain. Priority = airway. Swelling can press on the windpipe. Check swallowing and hoarseness. Read in book Iggy Ch. 37, pp. 929–937 · crossed-out parts left out (muscle relaxant list, ziconotide, failed back surgery syndrome) Nonsurgical care (book pp. 932–933)Read in book - Non-drug measures come first. A short period of bed rest with heat may help; heat gives short-term relief. - Start stretching and resume normal activity as soon as possible. Aerobic exercise has good evidence. - Change position often: long standing, sitting, or lying increases pain. Shoe insoles or floor pads can help. - Williams position for acute low back pain from a bulging or herniated disc. - Reassure patients: many fear the pain won't go away. Most won't have another episode with good care. - Chronic pain: stress reduction, mindfulness, progressive muscle relaxation, yoga. cognitive behavioral therapy (CBT) + physical therapy (PT) helps pain lasting over 12 months. - McKenzie exercises (extension and flexion) move pain toward the center of the back. Start only after acute pain eases. Water therapy builds muscle without strain. - Weight loss if more than 10% over ideal weight. Meds & muscle relaxant alert (book)Read in book - nonsteroidal anti-inflammatory drugs (NSAIDs) (aspirin, ibuprofen, naproxen) help. - Antidepressants and gabapentin are often prescribed, but national guidelines don't recommend them for low back pain (antidepressants OK if the patient is also depressed). - Opioids: very limited role, used sparingly and short-term for acute pain. - Topical capsaicin: short-term relief. Lidocaine patches: no real benefit. - Ziconotide: strong analgesic for severe persistent pain. Drug Alert: centrally acting muscle relaxants cause sedation, dizziness, lightheadedness and anticholinergic effects (dry mouth, urinary retention, blurred vision, constipation, tachycardia). Avoid in older adults (falls). No driving, alcohol, or other central nervous system (CNS) depressants. Metaxalone can damage the liver. Surgery details (book)Read in book Done when conservative care fails or neuro deficits keep getting worse. minimally invasive surgery (MIS) isn't used if the disc presses on the spinal cord. Pre-op teaching: getting in and out of bed, turning, report new numbness, tingling, or weakness in the legs, home restrictions. | Minimally invasive | Open | | --- | --- | | Microdiskectomy (1-inch incision, endoscope) · PED (percutaneous endoscopic diskectomy, may add laser) · Laser-assisted laparoscopic (belly-button incision; bulging discs only; risks: infection, nerve root injury) · robot-assisted. Home same day or in 23–48 hrs. | Diskectomy (remove disc) · laminectomy (remove part of the lamina) · spinal fusion (bone graft, metal rods/screws) · interbody cage fusion (titanium mesh) · artificial disc. Pain control may use intrathecal or epidural patient-controlled analgesia (PCA). | Open-surgery complications: nerve injury, diskitis (disc inflammation), dural tears. - Book: vital signs (VS) at least every 4 hrs for 24 hrs (fever, hypotension, severe pain); neuro checks every 4 hrs (movement, strength, sensation in legs). - Check ability to void after catheter removal. Pain and lying flat make voiding hard, especially for men. Lecture said VS every hour for the first 4–6 hrs, then every 4 hrs. The book only says "at least every 4 hrs." Use your instructor's version for exams. Causes & risk factorsRead in book - Muscle strain or spasm, ligament sprain, disk degeneration, herniated nucleus pulposus (HNP). - Spinal stenosis: narrowing of the spinal canal, usually over age 50. - Most common in ages 30–60; women a bit more than men. - Risks: heavy lifting, falls, crashes, repetitive bending and twisting, obesity, smoking (less blood flow to disks), scoliosis. - Older adults: osteoporosis, vertebral fractures, arthritis. Prevention (Box 37.5)Read in book - Safe lifting; ask for help with heavy chores. - Regular exercise: swimming, walking, back strengthening. - No high heels; good posture; footstool and ergonomic chairs. - Avoid prolonged sitting or standing. - Weight within 10% of ideal. Enough calcium and vitamin D. - Stop smoking. Nurses: avoid lifting patients by hand. Use the lift equipment. AssessmentRead in book - Main complaint: continuous pain. Stiff, flexed posture; limp; can't bend. - Sciatic pain: sharp, burning down the back of the thigh or calf, maybe to the ankle or toes. Worse with sneezing, coughing, straining. - Raising the straight leg causes severe pain (nerve compression). - Check both legs for sensation (cotton ball, paper clip) and strength. - Ask about bladder or bowel changes (new incontinence or retention). - Ask about sadness and suicidal thoughts with persistent pain. - Tests: imaging only if severe; electromyography (EMG) and nerve conduction studies. Treatment & meds (slides)Slides Diagnosis: magnetic resonance imaging (MRI), electromyography (EMG), nerve conduction study. Interventions: positioning · moist heat or cold · physical therapy · weight control · complementary therapies · meds (NSAIDs, muscle relaxants, gabapentin, tramadol, epidural injection). | Class | Examples | | --- | --- | | NSAIDs (block prostaglandins → less inflammation and nerve sensitivity) | over-the-counter (OTC): aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve). Rx: celecoxib (Celebrex), meloxicam (Mobic) | | Muscle relaxants | Baclofen, cyclobenzaprine (Flexeril), tizanidine (Zanaflex), methocarbamol (Robaxin) | Surgery: minimally invasive (microscopic or endoscopic discectomy: shorter stay, less blood loss and pain) or open (discectomy, laminectomy, spinal fusion). Post-op (slide): vital signs (VS) hourly for 4–6 hrs, then every 4 hrs (fever, ↓blood pressure (BP), tachycardia) · neuro checks (movement, strength, sensation) · cerebrospinal fluid (CSF) leak signs → head of bed (HOB) flat and call the provider · ability to void · log roll · pain control. After lumbar surgery (Table 37.2)Read in book | Complication | Watch for / do | | --- | --- | | cerebrospinal fluid (CSF) leak | Clear fluid on dressing; "halo" ring. Lay flat, report to surgeon now. | | Fluid deficit | I&O, hypotension, tachycardia | | Urinary retention | Get them to the bathroom early; men may stand to void | | Paralytic ileus | Flatus or stool, distention, N/V | | Fat embolism | Chest pain, dyspnea, anxiety, confusion; petechiae on neck, chest, mouth | | Nerve root pain | Pain not relieved by meds | | Infection | Temp spike after day 2 post-op | Critical Rescue: a sudden headache + clear drainage = possible CSF leak. Keep on bed rest, lower the head of the bed, report right away. Bulging at the incision = CSF leak or hematoma. - Log roll every 2 hrs. No overhead trapeze (strains the back). - Sit in a straight-back chair, feet flat. - venous thromboembolism (VTE) prevention: early mobility, compression devices, anticoagulant. Home (first 4–6 weeks): limit stairs and driving · lift nothing over 5 lb · no bending or twisting · walk daily. Clear drainage from incision → call the surgeon. Spinal cord stimulation may help persistent pain: check neuro status below the device and make sure they can void. Cervical neck painRead in book - Usually a herniated disk at C5–C6 or C6–C7. - Pain radiates to the shoulder and arm with numbness or tingling; may disrupt sleep. - Conservative care: exercises (shoulder shrugs, squeezes); soft collar at night, no longer than \~10 days. - Surgery: anterior cervical discectomy and fusion (ACDF) (fusion with bone graft) or newer anterior interbody cervical fusion (AICF)/lateral interbody cervical fusion (LICF) (titanium device; shorter recovery). Collar for 2–3 weeks after ACDF. After ACDF, priority = airway. Neck swelling can narrow the trachea; the surgery can affect swallowing. Check swallowing and breathing; keep suction ready; sit upright; report changes now. Box 37.6 discharge: someone stays with them the first few days · no lifting · no driving until cleared · walk daily · call if pain, numbness, or swallowing get worse. Book · Mastery Q3 · Select all A nurse teaches a community group about preventing back injury. Which recommendations are correct? Log rolling is post-op care, not prevention. Everything else is in Box 37.5. Review class: after disc surgery Review class From the in-class exam review (Joline case study + NCLEX questions). - Distended bladder = urinary retention → possible spinal nerve damage. Priority finding. - Reposition every 2 hours (not every 4). - Nothing by mouth (NPO) is based on sedation / gag reflex return, not on whether they've voided or have nausea. - An indwelling catheter, echo, or dietary assessment isn't needed unless the story gives a reason. Quick recall · tap to flip NCLEX Best position for a client with low back pain? Bent knees take pressure off the nerve and relax back muscles. NCLEX After lumbar fusion, a client wants to use the overhead trapeze. Best response? No twisting after back surgery. NCLEX After a laminectomy, the dressing has a clear ring around blood and the client has a sudden headache. First action? Halo sign + headache = possible CSF leak. The 60-second version ## Problems in the wires outside the brain and cord - Myasthenia gravis: muscles get weak with use. Keep meds with them always. - Peripheral nerve injury: protect the numb area. - Trigeminal neuralgia (CN V): lightning-bolt face pain. - Bell's palsy (CN VII): one side of the face droops. Protect the eye. Cranial nerves: your instructor said don't memorize all 12. Know V (trigeminal) and VII (facial), plus the swallowing nerves IX (glossopharyngeal) and X (vagus) from the stroke lecture. Myasthenia gravis: what it is Acetylcholine is a key. The muscle has locks. In myasthenia gravis (MG), the immune system jams the locks, so the key can't make the muscle move. - Autoimmune. Attacks acetylcholine receptors where nerve meets muscle. - Extreme fatigue; muscles weaken very easily. - First: eyes (droopy eyelid = ptosis, double vision). Then face: hard to smile, chew, swallow, shave, brush teeth. - Advanced: all muscles, including bowel, bladder, and breathing. Edrophonium test & pyridostigmine Edrophonium (Tensilon) test: gives more acetylcholine. myasthenia gravis (MG) → muscles improve within 1 minute, lasting 4–5 min. Can cause serious bradycardia. Atropine (the antidote) must be at the bedside. Pyridostigmine: keeps more acetylcholine around. Controls symptoms; doesn't cure. - Dose can change day to day (weaker days = higher dose). - Eat 45–60 min after the dose: muscles strongest → no aspiration. Myasthenic vs. cholinergic crisis | | Myasthenic crisis | Cholinergic crisis | | --- | --- | --- | | Cause | Not enough medicine | Too much medicine | | Edrophonium test | Muscles improve | No improvement; may get weaker | | Clue | Worsening weakness, breathing trouble (may need ventilator) | Extra secretions: drooling, sweating, lung secretions | | Treat | More medicine | Atropine | Memory trick: cholinergic = "too much choline" = too much fluid pouring out (spit, sweat, secretions). Other myasthenia gravis (MG) treatments - Steroids (calm the immune system). - Plasmapheresis & intravenous immunoglobulin (IVIG): short-term only, for emergencies like breathing distress. Work fast; last weeks to a couple of months. - Plasmapheresis = filters out the plasma carrying the bad antibodies; returns the blood cells. Watch for: low blood pressure (BP) (fluid loss), electrolyte imbalance, hypothermia, access-site infection. - IVIG = donor antibodies that block the bad antibodies. - Thymectomy = remove the thymus. MG is linked to a thymus tumor, and the bad antibodies are made there. myasthenia gravis (MG) nursing care - Breathing support first. - Plan activities around peak medicine times. - Keep pyridostigmine with them always: nightstand, car, work. - Rest is essential. Repetitive movement can trigger a myasthenic crisis. - Help with communication and nutrition (weak face muscles). - Eye protection at night (eyes may not close); artificial tears during the day. Peripheral nerve injury From a cut, burn, crush, stretch, and more. The nerve past the injury dies back → weakness, limp paralysis, burning, numbness. - Both nerve ends try to grow back together. Lined up → normal function. Not lined up → weakness, spasms, less feeling. - Infection or older age slows healing. - Some function can return early through backup (collateral) nerves. - Treatment: splint or cast to rest it; surgery to realign the ends. Teach: they can't feel the area well → protect it. Cover it in cold and heat. Keep skin moisturized. Trigeminal neuralgia (CN V) Irritated cranial nerve 5 (one on each side of the face) → one-sided, excruciating, sharp, shooting bursts of pain. - Triggers: touch, chewing, brushing teeth, even smiling. Patients start avoiding these things. Priority = pain management. 1. Antiepileptics: carbamazepine (Tegretol), gabapentin, pregabalin. 2. Nerve block. 3. Surgery (see below). - Rhizotomy: heated needle destroys nerve fibers → that side is permanently numb. Teach to look for injuries (poked eye, cavity) they can't feel. - Microvascular decompression: moves an artery pressing on the nerve. More serious: needs a craniotomy. Bell's palsy (CN VII) Sudden paralysis of the facial nerve (CN 7), triggered by the herpes simplex virus waking up (infection, cold exposure). - One side of the face: can't close the eye, smile, or wrinkle the forehead. Taste is affected. - Can hurt body image. - Antivirals: acyclovir, valacyclovir. - Protect the eye (can't blink or close it). - Nutrition, massage, warm moist heat, facial exercises, emotional support. - Most recover fully in weeks to months; a few keep some weakness. Review class: myasthenia gravis + trigeminal neuralgia Review class From the in-class exam review (Joline case study + NCLEX questions). Pyridostigmine: cholinesterase inhibitor for myasthenia gravis. Keeps more acetylcholine around so nerve signals reach the muscles. - Never miss a dose. - Take it so it peaks before activities that need energy, like eating. Eating at a low level → weak swallow → aspiration. - Dose changes daily based on symptoms and energy (like sliding-scale insulin). Exception to the rule! | Myasthenic crisis | Cholinergic crisis | | --- | --- | | Not enough pyridostigmine → weakness, poor oxygenation | Too much pyridostigmine ("cholin-" is in the name) | - Plasmapheresis (myasthenia gravis treatment) risks: fluid and electrolyte loss, blood pressure changes, site infection. - Trigeminal neuralgia: brushing teeth or shaving triggers intense pain, so patients may stop doing them. Address hygiene. Quick recall · tap to flip NCLEX A client with myasthenia gravis (MG) has severe weakness, drooling, sweating, and heavy lung secretions after extra pyridostigmine. The nurse suspects: Too much medicine → too much acetylcholine → secretions. Atropine reverses it. NCLEX Most important teaching for an MG client going home on pyridostigmine? Weakness can hit anytime. Eat 45–60 min after the dose, and rest often. NCLEX Priority teaching for a client with Bell's palsy? The eye can't close, so it can dry out and get hurt. NCLEX A client with a nerve injury to the hand is going outside in winter. Best teaching? Decreased sensation means they can't sense cold or heat injury. Cover it and keep skin hydrated. The 60-second version ## Every med from your lectures & slides, in one place - Only meds your instructor mentioned (no book-only drugs). - ★ = your instructor stressed it most. - Learn the one big safety point for each, not every detail. Think of each drug as having one "headline." Sinemet: no protein. Phenytoin: gums. Pyridostigmine: eat 45–60 min later. Mannitol: hourly urine. Migraine | Drug | Know this | | --- | --- | | Acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs) (ibuprofen, naproxen), over-the-counter (OTC) + caffeine (Excedrin) | First try. Caffeine narrows vessels. Take at first sign/aura. | | ★ Triptans: sumatriptan (Imitrex), rizatriptan (Maxalt) | Activate serotonin → narrow vessels. NO with heart disease, hypertension (HTN), peripheral vascular disease (PVD). Report chest pain. No selective serotonin reuptake inhibitors (SSRIs) or St. John's wort (serotonin syndrome). | | Lasmiditan | Doesn't narrow body vessels. Causes sedation, dizziness. | | Prevention: NSAIDs, beta blockers, topiramate | For frequent or severe migraines | Rebound headache = taking meds too often or too much. Seizures | Drug | Know this | | --- | --- | | ★ Phenytoin (Dilantin) | Gingival hyperplasia → soft toothbrush, dentist | | Carbamazepine (Tegretol), valproic acid (Depakote), topiramate (Topamax) | Same class rules below | All anti-seizure meds: drowsiness · depression/suicidal thoughts · liver damage · low white blood cells (WBCs) · blood levels (narrow range) · never stop suddenly (status epilepticus) · pregnancy category D · birth control less effective (use 2nd method) · watch warfarin · no grapefruit. Status epilepticus: 1. ★ Lorazepam (Ativan) or diazepam (Valium) intravenous (IV) → stops the seizure 2. Fosphenytoin (preferred, safer) or phenytoin → prevents the next one Meningitis - Broad-spectrum antibiotic right away (after blood cultures) if ↑intracranial pressure (ICP) signs. Switch to narrow-spectrum once the germ is known. - Vaccines: meningococcal (age 11–12, booster 16), flu, pneumonia. Parkinson's | Drug | Know this | | --- | --- | | ★ Carbidopa-levodopa (Sinemet) | Replaces dopamine. Nausea → take with carbs, NOT protein. Long-term: dyskinesia, "on-off." | | Dopamine agonists | Impulse control problems (gambling). Not for older adults. | Tolerance (stops working) or toxicity (delirium) → lower dose, change meds, or drug holiday (1 week–10 days). multiple sclerosis (MS) (only 2 to know) | Drug | Know this | | --- | --- | | ★ Interferon beta | Shot under the skin. Infection risk, bone marrow suppression, flu-like symptoms | | ★ Glatiramer | Shot under the skin. Fewer side effects | Both slow the disease and make attacks fewer and milder. No cure. Spinal cord injury - Nifedipine or a nitrate → autonomic dysreflexia (after sitting up and fixing the cause). - Fluids, vasopressors → neurogenic shock. - Low molecular weight heparin → prevent blood clots. - Stool softeners → constipation. Back & neck pain | Drug | Know this | | --- | --- | | nonsteroidal anti-inflammatory drugs (NSAIDs) (first choice): aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), celecoxib (Celebrex), meloxicam (Mobic) | Block prostaglandins. Side effect: gastrointestinal (GI) upset. Adverse: bleeding | | Muscle relaxants: baclofen, cyclobenzaprine (Flexeril), tizanidine (Zanaflex), methocarbamol (Robaxin) | Drowsiness, fatigue (act on central nervous system (CNS)) | | Gabapentin | Anti-seizure drug for nerve pain | | ★ Tramadol (Ultram) | If an opioid is needed: least potent, low dependency | | Epidural injection | Steroid + numbing med | Myasthenia gravis | Drug | Know this | | --- | --- | | ★ Pyridostigmine | Keeps more acetylcholine (ACh) around. Eat 45–60 min after (no aspiration). Carry it always. Dose changes daily. | | Edrophonium (Tensilon) | Test drug. myasthenia gravis (MG) improves within 1 min. Can cause bradycardia. | | ★ Atropine | Antidote for edrophonium; treats cholinergic crisis. Keep at bedside. | | Corticosteroids, intravenous immunoglobulin (IVIG) | Calm the immune system; IVIG is short-term for crises | Too little med = myasthenic crisis. Too much = cholinergic crisis (secretions). Trigeminal neuralgia & Bell's palsy - Trigeminal: carbamazepine (Tegretol), gabapentin (Neurontin), pregabalin (Lyrica); nerve block. - Bell's palsy: antivirals acyclovir, valacyclovir (HSV-1). Stroke & transient ischemic attack (TIA) | Drug | Know this | | --- | --- | | ★ tissue plasminogen activator (tPA) (alteplase) | Ischemic only. Within 3 (up to 4.5) hrs of symptom onset. computed tomography (CT) first. Bleeding risk. Repeat CT after. | | Antiplatelets: aspirin, clopidogrel | Prevent clots. Both together = dual antiplatelet therapy | | Anticoagulants: heparin, warfarin, direct oral anticoagulants (DOACs) | For A-fib | | Aspirin 325 mg | 24–48 hrs after stroke. Not within 24 hrs of tPA | | Statin | Must be discharged on one (core measure) | | Enoxaparin / heparin | Prevent blood clots | | Anti-seizure meds | Hemorrhagic stroke (seizure ↑intracranial pressure (ICP)) | Head injury & intracranial pressure (ICP) | Drug | Know this | | --- | --- | | ★ Mannitol | Pulls water out of the brain. Osmolality goal 310–320. Hourly urine (Foley). Watch dehydration, electrolytes, kidney injury. | | Furosemide | Given with mannitol; removes fluid from the body | | Hypertonic saline (3% or 5%) | Works like mannitol. intensive care unit (ICU) only | | Acetaminophen | Concussion pain. No nonsteroidal anti-inflammatory drugs (NSAIDs) (bleeding) | Dialysis (kidney lecture) - Hold antihypertensives and antidysrhythmics until after (low blood pressure (BP)). - Give after: antibiotics, anticonvulsants, vitamins (dialyzed out). - Heparin during dialysis lasts 4–6 hrs. Antidote: protamine sulfate. Review class: med "exceptions" she stressed Review class From the in-class exam review (Joline case study + NCLEX questions). - Mannitol: filter needle; dose by serum osmolality (goal 310–320); intake and output (I&O); sodium, potassium. - Propranolol prevents migraine; triptans abort it (avoid with hypertension, peripheral vascular disease, angina, selective serotonin reuptake inhibitors (SSRIs)). - Diazepam/lorazepam stop status epilepticus; phenytoin/fosphenytoin only prevent future seizures. - Ropinirole: careful in older adults (orthostatic hypotension). Carbidopa-levodopa: with food, not protein. - Pyridostigmine: don't miss doses, take before eating, dose changes daily. Quick recall · tap to flip NCLEX Which med should the nurse hold before a client's dialysis? Antihypertensives wait until after dialysis (low blood pressure (BP) risk). NCLEX A client on phenytoin says, "I feel fine, so I stopped my pills." Priority concern? Stopping anti-seizure meds suddenly can trigger status epilepticus. NCLEX Which client should NOT get sumatriptan? Triptans narrow vessels everywhere. NCLEX A client on a dopamine agonist starts gambling heavily. The nurse: Impulse control problems are a known adverse effect. The 60-second version ## Dialysis = an artificial kidney - Started based on symptoms, not lab numbers. - Fistula/graft arm: feel the thrill, hear the bruit. No blood pressure (BP), intravenous lines (IVs), or sticks in that arm. - Hold antihypertensives and dialyzable meds until after dialysis. - After: watch for low BP and bleeding (heparin lasts 4–6 hrs). - Peritoneal dialysis: biggest risk = peritonitis. The dialyzer is a coffee filter. Blood flows on one side, a clean solution (dialysate) on the other. Waste and extra fluid pass through the filter and get thrown away. Note: this is renal (kidney) content from a different lecture. It's here because you asked to add it. What dialysis is - Kidney replacement therapy = umbrella term for dialysis or transplant. Those are the only 2 options. - Used when kidneys fail (acute or chronic) to remove extra fluid and waste. - Blood passes through an artificial semipermeable membrane in the dialyzer (artificial kidney). - Dialysate = solution that looks like plasma. Fixes electrolytes and acid-base balance. Pause activity: added vs. removed during dialysis. The answer slide wasn't in your transcript; standard answer: removed = urea (BUN), creatinine, potassium, uric acid, extra fluid; added = bicarbonate (fixes acidosis). Check against your slide. When to start dialysis - Based on signs and symptoms, NOT labs (BUN, creatinine, glomerular filtration rate (GFR)). - chronic kidney disease (CKD): started when uremic symptoms appear. Emergency dialysis: - Pulmonary edema - Severe electrolyte or acid-base imbalance, e.g., hyperkalemia with electrocardiogram (EKG) changes - Pericarditis Pause question: why does pericarditis need emergency dialysis? Standard answer: it's caused by uremic toxins irritating the heart sac. Fluid can build up around the heart → cardiac tamponade. Dialysis removes the toxins. Check against your slide. Intermittent vs. continuous | | Intermittent hemodialysis | Continuous (CRRT) | | --- | --- | --- | | Schedule | 3×/week, 4 hrs each | Over 24 hrs | | Flow | \~300–500 mL/min → big fluid shifts, blood pressure (BP) changes | Only 10–80 mL/min (gentler) | | Who | Stable patients | Unstable (heart problems) · intensive care unit (ICU) only | | Also called | — | Hemofiltration, ultrafiltration | Access: dialysis catheter Regular veins can't handle the high flow, so special access is needed. - Short-term (a few sessions or weeks). - Tip in the superior vena cava (just above the right atrium); 2 ports: one out to the machine, one back. - Watch for infection and bleeding at the site. - Sterile dressing changes by the dialysis nurse only, not floor nurses. Dialysis only. Nothing else goes through it: no intravenous (IV) fluids, no meds. Access: arteriovenous (AV) fistula or graft - Long-term dialysis. - Fistula = artery and vein sewn together in the arm. Graft = synthetic tube connects them. - Needs time to mature (fistula \~12 weeks). Meanwhile, a catheter is used, so a patient may have both. "Feel the thrill, hear the bruit." Thrill = palpate (buzzing). Bruit = auscultate (whooshing, like a loud murmur). Check and document every 4 hrs. Also check circulation below the site to the fingertips. Protect the arm (keep it from clotting): - No intravenous lines (IVs), no blood pressure (BP), no compression on that arm. - No carrying heavy things with it. - Don't sleep on it. Caring for patients after hemodialysis Meds: - Most meds are dialyzable (removed by dialysis). Give antibiotics, anticonvulsants, vitamins AFTER. - Hold antihypertensives and antidysrhythmics until after (dialysis already drops blood pressure (BP)). - Heparin is used during dialysis and stays active 4–6 hrs → no invasive procedures, watch for bleeding. Antidote = protamine sulfate. Vital signs for several hours: - Hypotension is the big risk. - Slightly warm temp is normal (dialysate is warmed: prevents hypothermia, vasodilation speeds toxin removal). Ongoing fever → infection or sepsis. Weights before and after. After = dry weight. 1 kg = 1 L of fluid. Peritoneal dialysis (PD) The peritoneum (belly lining) is the filter. Done at home; more freedom (even on vacation). Won't work with belly scarring or adhesions from past surgery. 1. Infuse: 1–2 L dialysate flows in by gravity. 2. Dwell: stays 4–8 hrs. Patient disconnects and walks around. Extra weight can cause back pain. 3. Drain: fluid flows out by gravity into a bag. Outflow = effluent. Types: continuous ambulatory (CAPD), small machines, or overnight while sleeping. Depends on needs and insurance. peritoneal dialysis (PD) complications | Problem | Fix | | --- | --- | | Peritonitis (#1) | From contamination at the connection. Sterile technique: hand hygiene, sterile gloves, clean and assess site, mask when connecting/disconnecting. | | Pain with infusion | Common the first 1–2 weeks. Warm the dialysate (warmer or heating pad). Never the microwave. | | Poor flow | Kinks or clots. Top causes: position (turn to other side, supine or low Fowler's, align body) and constipation (high fiber, stool softeners). | | Leakage | Clear fluid around catheter, from too much volume at first. Builds up to a full \~2 L over a couple weeks. | Non-compliance (Carlos) - Dialysis for life, 3–4 hrs, 3 days a week. Many feel denial: "I feel better, I'll skip today." - Find the reason first: money, work, no ride to the clinic. - Don't just tell them what to do. Ask what they're thinking and feeling. Class prep: how will you bring up non-compliance with Carlos? Try an open question, like "Tell me what makes getting to dialysis hard." Quick recall · tap to flip NCLEX A client returns from hemodialysis. Which order should the nurse question? Never use the access arm for IVs, BP, or compression. NCLEX A client is scheduled for dialysis at 0900. Which 0800 med should the nurse hold? Dialysis already lowers BP. Antihypertensives wait until after. NCLEX A client on peritoneal dialysis has cloudy effluent and belly pain. The nurse suspects: Peritonitis is the major PD complication, from contamination at the connection. NCLEX A client weighed 82 kg before dialysis and 79.5 kg after. How much fluid was removed? 82 − 79.5 = 2.5 kg = 2.5 L.
