Health History & Therapeutic Interviewing

• Signs vs. Symptoms:

  • Symptom: Subjective information reported by the patient regarding their personal sensations or health experience.
  • Sign: Objective information observed, measured, or detected directly by the nurse through physical assessment or testing.

• Subjective vs. Objective Data:

  • Subjective Data: What the patient says about themselves, their health history, and current symptoms.
  • Objective Data: What the nurse observes, inspects, palpates, percusses, auscultates, or measures during the physical examination.

• Purpose of Health History:

  • Establishes a detailed record of current and past health states.
  • Forms a baseline against which all future physiological and psychological changes can be measured.
  • Yields the first nursing diagnoses.
  • Provides the primary opportunity to build a therapeutic nurse-patient relationship.

• Four Patient Databases:

  • Complete Database (Baseline/Everything): A full health history and complete physical examination used to establish a baseline and identify current or past health problems.
  • Focused / Problem-Centered Database: A limited "mini" database targeted toward one short-term problem, cue complex, or single body system.
  • Follow-Up Database: Used to reassess an identified problem over time, evaluating whether it is improving, deteriorating, or unchanged, and how the patient is coping.
  • Emergency Database: Rapid, immediate collection of crucial information gathered simultaneously with life-saving interventions (airway, breathing, circulation, level of consciousness, disability). A complete database is collected after stabilization.

• Past Medical History (PMHx):

  • Childhood illnesses.
  • Accidents and injuries.
  • Serious or chronic illnesses.
  • Hospitalizations.
  • Operations and surgical procedures.
  • Immunizations.
  • Allergies: Document both the specific allergen AND the exact patient reaction; differentiate true physiological allergies from medication side effects.
  • Current and past medications.

• Family Medical History (FMHx):

  • Purpose: Highlights genetic or familial health risks to guide early disease screening and lifestyle risk reduction.
  • Scope ($3$ Generations Included):
    • Parents
    • Grandparents
    • Siblings
    • Aunts & Uncles
    • Nieces & Nephews
    • Cousins
  • Documented Details: Genogram symbols for gender, exact relationships, current age or age at death, and health conditions of blood relatives.
  • Target Familial Conditions: Heart disease, hypertension, stroke, diabetes mellitus, cancer, sickle cell anemia, mental illness, seizure disorders, kidney disease, tuberculosis.

• Ten Traps of Communication:

  1. False Reassurance: Minimizes patient feelings and blocks open, honest communication.
  2. Giving Unwanted Advice: Shifts decision-making control away from the patient; non-therapeutic.
  3. Using Authority ("I know best"): Creates a power imbalance and suppresses patient autonomy.
  4. Avoidance Language: Using euphemisms instead of naming direct issues increases patient anxiety.
  5. Distancing / Impersonal Speech: Referring to "the colon" or "the patient in room 4" instead of using names reduces trust.
  6. Professional Jargon: Medical jargon causes patient confusion, misunderstanding, and fear.
  7. Interrupting: Breaks rapport and stops the patient from fully expressing symptoms.
  8. Biased or Leading Questions: Drives the patient to give a specific answer rather than an objective truth.
  9. "Why" Questions: Implies judgment and puts the patient on the defensive.
  10. Making Assumptions: Presuming lifestyle, choices, or knowledge without explicit verification.

• Reflection Technique:

  • Echoes patient words back to them to encourage deeper detail.
  • Nurse repeats a key word or phrase spoken by the patient.
  • Demonstrates active listening and confirmation of understanding.
  • Prompts the patient to expand, clarify, or elaborate further.
  • Validates patient feelings.

• Question Types:

  • Open-Ended Questions: Unstructured, narrative questions that let the patient tell their story in their own words. Used to begin interviews, introduce new sections, or explore new topics.
  • Closed-Ended Questions: Structured questions requiring specific, short answers (e.g., yes/no). Used to fill in specific details, complete the Review of Systems (ROS), or maintain interview pace.

Assessment Techniques & General Survey

• Four Assessment Techniques (Standard Order):

  • Inspection (Look): Visual, auditory, and olfactory observation of size, color, shape, symmetry, and physical abnormalities.
  • Palpation (Feel): Using fingertips and hands to evaluate surface and organ characteristics. Light palpation evaluates skin surface/textures; deep palpation evaluates internal structures.
  • Percussion (Tap): Tapping the skin surface to produce resonance or dullness, revealing whether underlying structures are filled with air/gas, fluid, or solid tissue.
  • Auscultation (Listen): Using a stethoscope to hear sounds generated by blood, air, or internal organ movement.
  • Standard Sequence: Inspect $\rightarrow$ Palpate $\rightarrow$ Percuss $\rightarrow$ Auscultate. (Note: Abdominal sequence alters this order).

• Chief Complaint (CC):

  • A brief, spontaneous statement in the patient's own words stating the reason for seeking medical evaluation.
  • Includes $1$ or $2$ main symptoms/signs and their duration.
  • Documented verbatim in quotation marks without converting into diagnostic statements.

• History of Present Illness (HPI):

  • A chronological, detailed account of the chief symptom from its initial onset to the present moment.
  • The $6$ Key HPI Components:
    1. Location: Specific body area affected.
    2. Character / Quality: Descriptive nature of the pain or symptom (e.g., sharp, dull, burning).
    3. Quantity / Severity: Intensity scale (e.g., $1$ to $10$ pain rating).
    4. Timing / Onset: Exact start time, duration, and frequency.
    5. Aggravating / Relieving Factors: What exacerbates or alleviates the symptom.
    6. Patient's Perception: What the patient believes is happening.

• General Survey:

  • Begins at the very first moment of contact with the patient.
  • Provides an immediate overall impression of whole-person health.
  • Four Data Categories:
    1. Physical Appearance: Age, sex, skin color, facial features, signs of acute distress.
    2. Body Structure: Stature, nutritional status, symmetry, posture, position.
    3. Mobility: Gait, range of motion, ease of movement.
    4. Behavior: Facial expression, mood/affect, speech, personal hygiene.

Cardiovascular Assessment & Peripheral Vascular System

• Raynaud Phenomenon:

  • Mechanism: Vasospastic condition where exposure to cold or emotional stress causes severe constriction of small cutaneous terminal arteries in fingers and toes.
  • Triphasic Color Change Sequence:
    1. White (Ischemia): Arteriolar spasm cuts off perfusion.
    2. Blue (Cyanosis): Deoxygenated tissue blood pooling.
    3. Red (Reperfusion): Vasodilation and blood return.
  • Associated Symptoms: Coldness, numbness, tingling, and intense burning pain upon reperfusion.
  • Triggers: Cold temperatures, stress, vibration, tobacco smoking, caffeine intake.
  • Classification:
    • Primary Raynaud: Idiopathic, common, milder clinical course.
    • Secondary Raynaud: Associated with underlying autoimmune connective tissue diseases (e.g., systemic scleroderma, systemic lupus erythematosus); more severe with higher ulceration risk.
  • Nursing Care: Keep extremities warm, perform meticulous skin/ulcer checks, and avoid precipitating triggers.

• Lymphedema:

  • Pathophysiology: Obstruction or excision of lymphatic vessels (e.g., axillary node dissection, radiation therapy) causes protein-rich fluid to accumulate in interstitial spaces. High interstitial protein elevates local oncotic pressure, pulling additional fluid into tissues.
  • Clinical Presentation: Unilateral limb swelling; non-pitting, brawny edema with thickened, indurated skin.
  • Nursing Priority: Obtain baseline presurgical circumference measurements of both arms.

• Pulse Deficit Determination:

  • Calculation:$\text{Apical Heart Rate} - \text{Radial Pulse Rate} = \text{Pulse Deficit}$
  • Clinical Significance: A pulse deficit indicates weak ventricular contractions that fail to transmit a perfusion wave to peripheral arteries; frequently present in atrial fibrillation.

• Peripheral Pulse Assessment & Grading:

  • Grading Scale:
    • $3+$: Increased, full, bounding (Hyperkinetic states, fever, exercise, hyperthyroidism).
    • $2+$: Normal, expected pulse volume.
    • $1+$: Weak, thready, easily obliterated (Shock, Peripheral Artery Disease).
    • $0$: Absent, non-palpable.
  • Pulse Locations:
    • Radial: Thumb side of the anterior wrist, palmar forearm aspect.
    • Brachial: Antecubital fossa, medial to the biceps tendon.
    • Femoral: Directly below the inguinal ligament, halfway between anterior superior iliac spine and pubic symphysis.
    • Popliteal: Behind the knee; deep in the popliteal fossa with knee slightly flexed.
    • Posterior Tibial: Groove behind and slightly inferior to the medial malleolus.
    • Dorsalis Pedis: Dorsum of foot, lateral and parallel to the extensor tendon of the great toe.

• Heart Sounds ($S_1, S_2, S_3, S_4$):

  • $S_1$ (First Heart Sound): Caused by closure of the Atrioventricular (AV) valves (Tricuspid and Mitral). Signals the beginning of systole. Heard loudest at the apex.
  • $S_2$ (Second Heart Sound): Caused by closure of the Semilunar (SL) valves (Aortic and Pulmonic). Signals the end of systole / start of diastole. Heard loudest at the base.
  • $S_3$ (Third Heart Sound): Occurs in early diastole during rapid passive ventricular filling. Caused by blood colliding into a dilated, overfilled, non-compliant ventricle.
  • $S_4$ (Fourth Heart Sound): Occurs in late diastole immediately before $S_1$ ("atrial kick"). Caused by atrial contraction forcing blood into a stiff, hypertrophic, or resistant ventricle.

• Apical Pulse & Point of Maximum Impulse (PMI):

  • Anatomical Location: $5\text{th}$ intercostal space (ICS) at the left midclavicular line (MCL) — directly over the mitral valve area.
  • Mechanism: Left ventricular apex strikes the internal chest wall during early contraction.

• Heart Murmurs:

  • Acoustic Character: Gentle, blowing or swooshing sounds created by turbulent blood flow across valves or heart structures.
  • Best Auscultation Site: Erb's point ($3\text{rd}$ left ICS).

    • M - Mitral Regurgitation / Septal Defect

• Bruits and Thrills:

  • Bruits:
    • Assessment: Auscultated using the bell of the stethoscope over major vessels.
    • Key Locations: Carotid arteries, abdominal aorta, renal arteries, femoral arteries.
    • Significance: High-pitched blowing sound caused by turbulent blood flow through a narrowed or stenotic artery.
  • Thrills:
    • Assessment: Palpated using the palmar surface or ulnar border of the hand over the precordium.
    • Significance: Palpable physical vibration created by intense turbulent blood flow; indicates severe murmurs or structural cardiac defects.

• Peripheral Edema Evaluation:

  • Procedure: Firmly press thumb against pre-tibial surface or medial malleolus for exactly $5$\,\text{seconds}, release, and observe depression depth and recovery time.
  • Pitting Edema Scale:
    • $1+$: Mild pitting, slight indentation, no perceptible swelling of leg.
    • $2+$: Moderate pitting, indentation subsides rapidly.
    • $3+$: Deep pitting, indentation remains for short time, leg looks swollen.
    • $4+$: Very deep pitting, indentation lasts a long time, leg is grossly swollen and distorted.
  • Systemic vs. Localized Implications:
    • Bilateral Edema: Systemic underlying cause (e.g., Congestive Heart Failure, renal failure, hepatic insufficiency).
    • Unilateral Edema: Local vascular obstruction or inflammation (e.g., Deep Vein Thrombosis, lymphedema).
  • Documentation Standard: "2+ pitting edema noted to bilateral lower legs; indentation subsides rapidly. Findings consistent with systemic volume overload."

• Vascular Ulcer Etiologies:

• The Seven P's of Neurovascular Assessment:
  1. Pain: Severe, constant, disproportionate pain unrelieved by analgesics (earliest indicator of ischemia).
  2. Pallor: Pale, blanched, or cyanotic skin indicating arterial insufficiency.
  3. Pulselessness: Weak, diminished, or absent peripheral arterial pulse.
  4. Paresthesia: Numbness, tingling, or prickling sensation from nerve ischemia.
  5. Paralysis: Inability to move toes or fingers; late and ominous sign of muscular necrosis.
  6. Poikilothermia: Affected extremity assumes ambient environmental temperature; limb feels cold.
  7. Pressure: High tissue pressure within anatomical compartments; limb feels hard, firm, or tight.

Respiratory System & Thoracic Assessment

• Anatomical Landmarks for Auscultation:

  • Aortic Area: $2\text{nd}$ Right Intercostal Space at the right sternal border (Diaphragm).
  • Pulmonic Area: $2\text{nd}$ Left Intercostal Space at the left sternal border (Diaphragm).

  • Tricuspid Area: $4\text{th}$ Left Intercostal Space at the left lower sternal border (Diaphragm).
  • Mitral Area (Apex): $5\text{th}$ Left Intercostal Space at the midclavicular line (Diaphragm).

• Normal Breath Sounds:

  • Bronchial: Auscultated over the Trachea. Loud volume, high pitch, hollow/tubular quality. Expiration phase is longer than inspiration phase.
  • Bronchovesicular: Auscultated over major Bronchial Trees ($1\text{st}$ and $2\text{nd}$ ICS anteriorly, interscapular region posteriorly). Moderate pitch, moderate volume. Inspiration and expiration phases are equal in length.
  • Vesicular: Auscultated over peripheral Lung Fields. Soft volume, low pitch, rustling breeze sound. Inspiration phase is longer than expiration phase.

• Pulmonary Pathophysiology & Conditions:

  • Asthma:
    • Pathophysiology: Hyper-reactive airway constriction, bronchospasm, mucosal edema, and thick mucous secretion causing airway obstruction.
    • Clinical Findings: Auscultated wheezing, prolonged expiration phase, dyspnea, tachycardia, intercostal accessory muscle retraction, diminished vesicular breath sounds.
  • Pneumonia:
    • Pathophysiology: Acute infection of terminal bronchioles and alveolar sacs, leading to exudative consolidation.
    • Clinical Findings: Fever, malaise, pleuritic chest pain, localized coarse or fine crackles, increased tactile fremitus over consolidation.
  • Pneumothorax Types:
    • Closed Pneumothorax: Spontaneous or traumatic breach of visceral pleura leaking air into pleural space. Signs: Dyspnea, acute chest pain, tachypnea, cyanosis, distant or absent breath sounds on affected side, decreased chest excursion. Tracheal alignment may shift toward the unaffected side.
    • Open Pneumothorax: Penetrating thoracic wall trauma permitting air passage into pleural space.
    • Tension Pneumothorax: Univalvular air entry into pleural cavity where air enters on inspiration but cannot escape on expiration. High intra-pleural pressure compresses lungs and mediastinum.
    • CRITICAL EMERGENCY FINDING: Tracheal deviation AWAY from the affected side accompanied by severe hypotension, cyanosis, and respiratory failure.
  • Emphysema (COPD):
    • Pathophysiology: Permanent destruction of alveolar walls and hyperinflation of distal air sacs leading to loss of pulmonary elasticity and gas trapping.
    • Clinical Findings: Underweight physique, barrel chest development (increased anteroposterior-to-transverse ratio), pursed-lip breathing, tripod position, hyper-resonance on percussion, diminished breath sounds, occasional wheezing.
  • Congestive Heart Failure Dynamics:
    • Volume Overload (Left-Sided Heart Failure): Caused by valvular regurgitation or systemic shunts. Results in left ventricular dilation. Clinical Sign: Point of Maximum Impulse (PMI) is displaced laterally to the left and felt over a widened chest area.
    • Pressure Overload (Right-Sided Heart Failure / Hypertrophy): Caused by pulmonary hypertension or aortic stenosis. Ventricular muscle thickens without cavity expansion. Clinical Sign: PMI force/amplitude increases, but position is NOT laterally displaced.

• Adventitious Breath Sounds:

  • Stridor: High-pitched, monophonic, continuous inspiratory sound created by severe upper airway narrowing or obstruction at the larynx or trachea. Seen in Croup, Epiglottitis, and foreign body aspiration.
  • Wheezing: High-pitched, musical, continuous sound generated by air passage through acutely narrowed lower airways (bronchospasm, swelling). Common in Asthma and Chronic Bronchitis.
  • Crackles (Rales): Discontinuous, non-musical popping sounds created by air opening fluid-filled, collapsed alveoli.
    • Fine Crackles: High-pitched, short, popping sounds (sounds like rubbing hair strands together near the ear).
    • Coarse Crackles: Low-pitched, moist, bubbling sounds that do not clear completely with coughing. Seen in Pneumonia, Atelectasis, and Pulmonary Edema.
  • Pleural Friction Rub: Rough, dry, grating, or leathery sound caused by inflamed visceral and parietal pleura rubbing together. Heard during both inspiration and expiration; seen in Pleurisy, Pneumonia, and Pulmonary Embolism.

    • Bottom Number ($30$): Distance in feet at which a person with normal visual acuity can read that specific line.
    • $20/30$ indicates vision worse than normal ($20/20$).

• PERRLA Assessment:

  • P - Pupils
  • E - Equal in size
  • R - Round shape
  • R - Reactive to
  • L - Light (direct and consensual constriction)
  • A - Accommodation (pupils dilate for far vision; pupils constrict and axes converge for near vision)

• HEENT Findings Matrix:

  • Obtunded: Sleeps most of the time; difficult to arouse; requires loud verbal or mechanical shaking; confused and disoriented when awake.
  • Stuporous: Unconscious state; responds only to persistent, painful stimuli (e.g., sternal rub); responds with protective withdrawal or groaning.

• Glasgow Coma Scale (GCS):

  • Purpose: Standardized tool to measure level of consciousness and neurological impairment.
  • Scoring Parameters: Eye Opening ($1$ to $4$), Verbal Response ($1$ to $5$), Motor Response ($1$ to $6$).
  • Score Range: Maximum score = $15$ (fully awake, alert, oriented); Minimum score = $3$ (deep coma/death).
  • Intubation Threshold: An overall score of $\text{GCS} < 8$ indicates severe coma requiring airway protection and endotracheal intubation ("GCS less than 8, intubate").

• Indications for Focused Neurological Re-Assessment:

  • Any acute change in Level of Consciousness or orientation status.
  • New onset of focal motor weakness, facial droop, or sensory paresthesia.
  • Sudden change in pupillary size, equality, or light reactivity.
  • Post-fall trauma, head injuries, or suspected acute CVA.
  • Post-seizure activity.
  • Sudden vital sign shifts (e.g., Cushing's triad) indicating elevated intracranial pressure.

• Pain Perception in the Aging Adult:

  • Pain perception may be blunted or atypical due to neuro-sensory shifts.
  • Older adults may not demonstrate expected sympathetic responses (elevated heart rate or blood pressure) even during severe pain.
  • High risk for clinical undertreatment.
  • Unmanaged chronic pain directly degrades physical mobility, sleep quality, mood state, and functional independence.

• Acute vs. Chronic Pain Parameters:

  • Acute Pain: Sudden onset, short duration ($< 3$\,\text{months}); serves as a protective signal; produces sympathetic responses (tachycardia, elevated BP, tachypnea, diaphoresis).
  • Chronic Pain: Persistent pain lasting $> 3$\,\text{months}; non-protective; sympathetic responses adapt over time, leaving vital signs baseline normal; impairs daily functional activities, sleep, and psychological well-being.

• Phantom Limb Pain:

  • Pain localized to an amputated, missing extremity.
  • Caused by peripheral nerve misfiring and persistent central cortical memory processing.
  • A real physiological pain state requiring targeted pharmacological treatment (treated similarly to neuropathic pain).

Gastrointestinal & Nutritional Assessment

  • Right Lower Quadrant (RLQ): Cecum, Appendix, Ascending Colon, Right Ovary/Tube, Right Ureter.
  • Left Lower Quadrant (LLQ): Sigmoid Colon, Descending Colon, Left Ovary/Tube, Left Ureter.

• Rebound Tenderness (Blumberg Sign):

  • Elicited by pressing deep into the abdomen away from the painful area and releasing hand pressure abruptly.
  • Sharp pain upon quick release indicates peritoneal inflammation (peritonitis) as seen in acute appendicitis.

• Peristalsis Dynamics:

  • Rhythmic, wave-like muscular contractions of the gastrointestinal tract moving contents downward.
  • Factors slowing peristalsis: Immobility, general anesthesia, opioid analgesics, advanced age, surgical manipulation, and mechanical bowel obstruction.

• Abdominal Assessment Sequence & Rationale:

  • Correct Order: Inspection $\rightarrow$ Auscultation $\rightarrow$ Percussion $\rightarrow$ Palpation.
  • Rationale: Auscultation MUST precede percussion and palpation because mechanical touching or pressing on the abdominal wall stimulates intrinsic peristalsis, creating artificial bowel sounds.

• Bowel Sound Auscultation Protocol:

  • Auscultate for at least $1$\,\text{full minute} in each abdominal quadrant.
  • Must listen continuously for $5$\,\text{full minutes} before concluding that bowel sounds are completely absent.

• Nutritional Barriers in Diverse/Immigrant Populations:

  • Unavailability of traditional, culturally familiar food items.
  • Socioeconomic and financial constraints.
  • Language barriers affecting food label comprehension.
  • Disparity between host country dietary habits and cultural traditions.

• Therapeutic Diets:

  • Low Residue Diet: Minimizes indigestible fiber and soft tissue residue; prescribed for Ulcerative Colitis, Crohn's, and active diarrhea.
  • Low Protein Diet: Limits nitrogenous waste build-up; prescribed for severe Renal Failure.
  • Low Sodium Diet: Limits fluid retention; prescribed for Hypertension, Congestive Heart Failure, and Cirrhosis/Ascites.
  • Clear Liquid Diet: Transparent fluids at room temperature (water, broth, plain gelatin); used post-operatively or pre-procedure.
  • Full Liquid Diet: Includes all clear liquids plus opaque liquids (dairy, pudding, smooth cream soups).
  • Diabetic Diet: Strict carbohydrate-consistent counting; elimination of refined sugars.

  • Priapism: Persistent, painful erection lasting longer than $4$ hours without sexual arousal.
  • Cryptorchidism: Undescended testicle; failure of testicle to descend into the scrotum.
  • Menorrhagia: Abnormally heavy or prolonged menstrual bleeding.
  • Dysmenorrhea: Severe, painful abdominal cramping during menstruation.
  • Dyspareunia: Painful or difficult sexual intercourse.
  • Amenorrhea: Absence of menstruation.

• Hormonal Influence on Breast Tissue:

  • Cyclic fluctuations in estrogen and progesterone during the menstrual cycle cause physiological fluid retention, nodularity, tissue fullness, and tenderness prior to menses.

• Breast Self-Examination (BSE) Education:

  • Timing: Perform monthly, exactly $1$\,\text{week} after the onset of the menstrual cycle (when hormonal swelling is lowest).
  • Visual Inspection: Stand before a mirror to assess breast symmetry, skin dimpling, venous patterns, or nipple retraction.
  • Palpation Procedure: Use finger pads in a systematic vertical strip or circular motion while lying down and in the shower; cover the entire breast tissue including the Axillary Tail of Spence.
  • Reporting: Advise immediate evaluation for new hard lumps, dimpling, skin changes, or spontaneous nipple discharge.

• Menopause:

  • Etiology: Cessation of ovarian function and drop in estrogen production.
  • Clinical Manifestations: Hot flashes, night sweats, mood fluctuations, vaginal mucosal atrophy, dryness, dyspareunia, and irregular cycles ending in complete cessation.

• Reproductive Tract Infections:

  • Candida Vaginitis: Fungal yeast overgrowth. Signs: Thick, white, curdy ("cottage-cheese") vaginal discharge, severe vulvar pruritus, erythema, and burning.
  • Pediculosis Pubis: Infestation of pubic hair by lice (Phthirus pubis). Signs: Severe genital itching, visible lice, or small nits attached to hair shafts.
  • Syphilis: Systemic STI caused by Treponema pallidum.
    • Primary Stage: Single, painless chancre sore.
    • Secondary Stage: Maculopapular skin rash affecting palms and soles.
    • Tertiary Stage: Systemic cardiovascular and neurosyphilis lesions.
  • Chlamydia: Bacterial infection caused by Chlamydia trachomatis. Most common STI; often asymptomatic. Signs: Dysuria, mucopurulent vaginal/penile discharge, dyspareunia, lower pelvic pain.

• Urinary Tract Infection (UTI) Prevention:

  • Wipe perineum from front to back after voiding/defecation.
  • Maintain high oral fluid intake.
  • Void completely immediately following sexual intercourse.
  • Avoid feminine hygiene sprays, bubble baths, and scented products.
  • Avoid voluntary holding or delaying of urinary voiding.
  • Wear breathable cotton underwear.

• Benign Prostatic Hyperplasia (BPH):

  • Non-cancerous enlargement of the prostate gland surrounding the urethra; affects aging males.
  • Common Obstructive Symptoms: Weak, interrupted urinary stream, urinary hesitancy, post-void dribbling, nocturia, incomplete bladder emptying, urinary frequency, and urgency.

Musculoskeletal System Assessment

• Sprain vs. Strain:

  • Sprain: Traumatic stretching or tearing of a ligament (bone-to-bone connector).
  • Strain: Traumatic stretching or tearing of a muscle or tendon (muscle-to-bone connector).

• Tendons vs. Ligaments:

  • Tendons: Fibrous connective bands attaching muscle to bone.
  • Ligaments: Dense connective bands attaching bone to bone across joints.

• Diagnostic Test for Fractures:

  • X-Ray (Radiography): Standard diagnostic baseline to confirm skeletal fractures.

• Gouty Arthritis:

  • Pathophysiology: Hyperuricemia resulting in monosodium urate crystal deposition within joint spaces, triggering acute inflammatory responses.
  • Etiology: High purine intake, alcohol, dehydration, impaired renal uric acid excretion.
  • Clinical Presentation: Rapid onset of intense joint pain, severe erythema, localized heat, and pronounced swelling — most commonly affecting the First Metatarsophalangeal (MTP) joint (great toe).

• Active vs. Passive Range of Motion (ROM):

  • Active ROM: Joint movement executed entirely by the patient using their own muscular force.
  • Passive ROM: Joint movement executed by the nurse without active muscular contraction by the patient.
  • Clinical Indication for Passive ROM: Weakness, paralysis, structural immobility, or unconscious states.

• Range of Motion (ROM) Terminology:

  • Flexion: Decreasing the angle between two articulating bones (bending).
  • Extension: Increasing the angle between two articulating bones (straightening).
  • Abduction: Moving a limb away from the body midline.
  • Adduction: Moving a limb toward the body midline.
  • Circumduction: Moving a limb in a circular motion combining flexion, abduction, extension, and adduction.
  • Rotation: Turning a bone around its own central axis.
  • Pronation: Turning the forearm so the palm faces downward.
  • Supination: Turning the forearm so the palm faces upward.
  • Inversion: Turning the sole of the foot inward toward midline.
  • Eversion: Turning the sole of the foot outward away from midline.
  • Dorsiflexion: Flexing the foot upward toward the shin.
  • Plantar Flexion: Bending the foot downward toward the ground.

• Osteoporosis:

  • Pathophysiology: Severe loss of bone mineral density leading to porous, fragile bones and elevated fracture risk.
  • Primary Affected Population: Older post-menopausal women.
  • Rationale: Estrogen withdrawal decreases osteoblastic bone protection while aging reduces bone remodeling efficiency.

• Crepitus:

  • Audible or palpable crackling/grinding noise produced by articular friction between eroded bone cartilage surfaces or air trapped within soft tissues.

• Spinal Curvatures:

  • Lordosis: Exaggerated inward curvature of the lumbar spine ("swayback"); common in pregnancy and marked obesity.
  • Scoliosis: Abnormal lateral S- or C-shaped curvature of the spine.
  • Kyphosis: Exaggerated outward thoracic curvature ("hunchback"); common in aging adults with osteoporotic vertebral collapse.

• Osteoarthritis (OA) vs. Rheumatoid Arthritis (RA):

• Patient Positioning for Spinal Visual Assessment:
  • Patient stands fully upright, barefoot, with arms resting relaxed at sides.
  • Allows full observation of spinal alignment, shoulder height symmetry, scapular alignment, and thoracic cage structure.

Integumentary System & Pressure Injury Staging

• ABCDE Assessment Rule for Malignant Melanoma:

  • A - Asymmetry (one half does not match the other half)
  • B - Border irregularity (ragged, notched, blurred, or poorly defined edges)
  • C - Color variation (shades of brown, black, pink, red, white, or blue)
  • D - Diameter ($> 6$\,\text{mm} — size of a pencil eraser)
  • E - Evolving (dynamic changes in size, shape, color, elevation, or new bleeding/itching)

• Integumentary Changes in the Aging Adult:

  • Skin: Dermis thins, subcutaneous fat layer decreases, skin elasticity diminishes (elastosis), skin becomes dry, fragile, and experiences delayed wound healing.
  • Hair: Hair follicles atrophy, hair thins and turns gray due to loss of melanocytes.
  • Nails: Nails grow slowly, become brittle, rigid, dull, and develop longitudinal thickening.

• Cardiovascular-Integumentary Relationship:

  • Cutaneous tissue depends directly on cardiovascular systemic perfusion.
  • Assessed Clinical Markers: Capillary refill ($< 2$\,\text{seconds}), peripheral skin temperature, localized cyanosis or pallor, peripheral edema, and presence/loss of hair growth on lower extremities.

• Clubbing of the Nails:

  • Physical Sign: Loss of normal nail bed angle ($> 180^\circ$ angle between nail plate and proximal nail fold); nail bed feels spongy on palpation.
  • Pathophysiology: Chronic tissue hypoxia.
  • Associated Conditions: Chronic Obstructive Pulmonary Disease (COPD), Lung Cancer, Congenital Cyanotic Heart Disease.

• Skin Turgor Evaluation:

  • Assesses hydration status by pinching a fold of skin over the anterior sternum or below the clavicle.
  • Prompt return to resting flat position indicates normal hydration; slow return ("tenting") indicates significant dehydration.

• Skin Assessment in Darkly Pigmented Patients:

  • Pallor, cyanosis, and jaundice are best evaluated by examining sites of minimal skin pigmentation: oral mucous membranes, sclera, palmar surfaces of hands, plantar surfaces of feet, conjunctiva, and lips.

• Pruritus:

  • Intense skin itching sensation; triggered by primary dermatological disorders (eczema, dry skin), systemic hepatic/renal disease, or drug sensitivity reactions.

• Pressure Injury Staging & Variations:

• Stage 1 Pressure Injury (Nonblanchable Erythema):

  • Intact skin presenting with a localized area of nonblanchable erythema (does not turn white when pressed with a finger).
  • Light Skin: Area turns red and fails to blanch under direct fingertip pressure.
  • Dark Skin: Area appears darker, redder, or purplish than surrounding tissue and fails to blanch.

• Stage 2 Pressure Injury (Partial-Thickness Skin Loss):

  • Partial-thickness loss of dermis presenting as a shallow, open ulcer with a red-pink, moist wound bed without slough. May also present as an intact or open/ruptured serum-filled blister.
  • Light Skin: Shallow open ulcer with red-pink moist bed.
  • Dark Skin: Shows loss of superficial epidermis; underlying bed appears darker.

• Stage 3 Pressure Injury (Full-Thickness Skin Loss):

  • Full-thickness loss of skin in which subcutaneous fat is visible within a deep crater, but bone, tendon, and muscle are NOT exposed or visible.
  • Light Skin: Visible yellow slough or brown/black eschar inside wound bed.
  • Dark Skin: Slough or eschar present; surrounding intact skin displays deep hyperpigmentation.

• Stage 4 Pressure Injury (Full-Thickness Tissue Loss):

  • Full-thickness skin and tissue loss with directly visible or palpable muscle, tendon, ligament, cartilage, or bone. Slough or eschar may be present on some parts of the wound bed; often includes undermining and tunneling.

• Unstageable Pressure Injury:

  • Full-thickness tissue loss in which the actual depth and base of the ulcer are completely obscured by overlying slough (yellow, tan, gray, green, or brown) or eschar (tan, brown, or black) in the wound bed.

• Deep Tissue Pressure Injury (DTPI):

  • Intact or non-intact skin presenting with a localized area of persistent, non-blanchable deep purple or maroon discoloration, or blood-filled blister. Reflects tissue damage originating in muscle/soft tissue directly adjacent to the underlying bone.

• Vulnerable Bony Prominences:

  • Anatomical areas with high risk for pressure injury development include the sacrum, heels, ischium (buttocks), trochanters (hips), and elbows.
