Anticoagulant Therapy
- Purpose: Prevent clot formation/extension.
- Common meds:
- Heparin: IV/SQ, short-acting.
- Warfarin: Oral, long-acting, requires INR monitoring.
- DOACs: Apixaban, rivaroxaban.
- Nursing: Watch for bleeding, check labs (aPTT for heparin, INR for warfarin), educate on bleeding precautions.
INR Ranges
- Used for warfarin monitoring.
- Normal (no anticoagulation):
- Therapeutic Range:
- Most uses: 2.0–3.0
- Mechanical heart valve: 2.5–3.5
- Nursing: Monitor to avoid bleeding/clotting.
SSRI Premedication Assessment
- Mental Status: Mood, suicidal thoughts.
- Med History: MAOIs, anticoagulants.
- Physical: Weight, appetite, sleep, liver/renal function if needed.
- Other: Watch for serotonin syndrome.
SSRIs vs. TCAs
Feature SSRIs TCAs Mechanism Inhibit serotonin reuptake Inhibit serotonin & norepinephrine reuptake Examples Fluoxetine, sertraline Amitriptyline, imipramine Adverse Effects GI upset, insomnia, sexual dysfunction Anticholinergic, sedation, cardiac toxicity Overdose Risk Low High (can be fatal) MAOI Nursing Assessment
- Before: Check BP (hypertensive crisis risk), med/diet history (tyramine).
- Teach: Avoid aged cheese, wine, decongestants. Report headache, palpitations.
- Drugs: Phenelzine, tranylcypromine
SNRIs Nursing Responsibilities
- Examples: Venlafaxine, Duloxetine, Desvenlafaxine.
- Action: Inhibit serotonin and norepinephrine reuptake.
- Nursing:
- Baseline weight/BP.
- Monitor GI/CNS symptoms.
- Watch for hypertension, hepatic/renal issues.
- Teach about sedation, avoid machinery if dizzy.
- Taper when stopping.
- Monitor suicidal thoughts.
TCAs Adverse Effects
- Common: Dry mouth, constipation, urinary retention, orthostatic hypotension, sedation, dizziness.
- Serious: Cardiac toxicity (fatal overdose).
- Nursing: Avoid other CNS depressants, assess suicide risk, monitor vitals/ECG.
Lithium Adverse Effects
- Therapeutic range: 0.4–1.2 mEq/L
- Common: Nausea, tremor, polyuria.
- Serious Toxicity: Vomiting, hyperreflexia, nephrotoxicity, seizures.
- Nursing: Monitor hydration, electrolytes, renal/thyroid function, watch for toxicity signs.
Blood Clot Treatment/Prevention
- Anticoagulants: Heparin (aPTT), Warfarin (INR), DOACs (factor Xa inhibitors).
- Antiplatelets: Aspirin, clopidogrel.
- Thrombolytics: Alteplase (dissolve clots).
- Prevention: Early ambulation, compression stockings.
Psychotic Behavior S/Sx
- Positive: Delusions, hallucinations, disorganized thinking/behavior.
- Negative: Flat affect, alogia, asociality, anhedonia, poor hygiene.
Antipsychotic Uses/Adverse Effects
- Treats: Schizophrenia, mania, psychotic depression, bipolar, autism irritability.
- Adverse: EPS, weight gain, hyperglycemia, agranulocytosis, QT prolongation, anticholinergic effects.
Seizure Disorders/Meds
- Disorders: Generalized, partial, status epilepticus.
- Meds: Phenytoin, valproic acid, carbamazepine, levetiracetam.
- Nursing: Monitor drug levels (phenytoin: 10–20 mcg/mL), seizure activity, adverse effects, safety, adherence.
Opiate Agonists
- Action: Relieve pain, suppress cough, reduce anxiety by binding to opioid receptors.
- Examples: Morphine, hydromorphone, fentanyl, oxycodone.
- Adverse: Respiratory depression, hypotension, sedation, nausea, constipation, dependence.
- Nursing: Monitor respiratory rate, pain/sedation, encourage fluids/fiber, watch for overdose.
Naloxone
- Use: Reverses opioid overdose/respiratory depression.
- Outcome: Restores breathing and consciousness.
- Nursing: Monitor respiratory rate, LOC, BP, watch for withdrawal.
Salicylates
- Action: Analgesic, anti-inflammatory, antipyretic, antiplatelet.
- Adverse: GI upset, ulcers, bleeding, tinnitus, Reye’s syndrome.
- Nursing: Monitor GI, bleeding, avoid in children with viral illness, take with food.
Angina/Nitrates
- Angina Types:
- Chronic stable: Predictable, relieved by rest/nitroglycerin.
- Unstable: Unpredictable, severe, not relieved by rest.
- Nitrates: Dilate veins/arteries, ↓ preload & myocardial oxygen demand.
- Uses: Acute attacks (sublingual) and prevention (patches, oral).
- Adverse: Headache, dizziness, hypotension.
- Teaching: Storage, timing, fall precautions.
- Angina Types:
Hypertensive Medications
- Drug Classes: Diuretics, ACE inhibitors, ARBs, beta-blockers, calcium channel blockers, alpha-1 blockers, vasodilators.
- Nursing: Monitor BP, adherence, side effects. Teach medication timing, home BP checks. Encourage lifestyle changes.
- Lifestyle: ↓ sodium, weight loss, physical activity, smoking cessation.
Atherosclerosis
- Atherosclerosis: Plaque buildup in arteries → CAD, stroke.
- Meds: Statins (lower LDL), PCSK9 inhibitors, bile acid resins, ezetimibe.
- Aim: Slow progression, prevent MI.
Hyperlipidemia
- Hyperlipidemia: High cholesterol/triglycerides → atherosclerosis and CAD.
- Meds: Statins, niacin, fibrates, omega-3s, PCSK9 inhibitors, bile acid
