Medications to Know for NCLEX 2023 Introduction The NCLEX exam tests a nursing graduate’s ability to apply critical thinking and knowledge to real-life clinical scenarios. Among the most challenging aspects of the exam is the pharmacology section, as it requires not only memorization of drugs but also understanding their mechanisms, uses, side effects, and nursing implications. Below is a guide to some of the most commonly tested medications and drug categories that you need to know for the NCLEX in 2023. 1. Cardiovascular Medications Cardiovascular drugs are frequently tested on the NCLEX. Here are some key classes and medications to know: ACE Inhibitors (e.g., Lisinopril, Enalapril) Uses: Hypertension, heart failure Mechanism: Prevents conversion of angiotensin I to angiotensin II, reducing blood pressure Side Effects: Cough, hyperkalemia, angioedema Nursing Implications: Monitor potassium levels, educate on side effects like persistent cough Beta-Blockers (e.g., Metoprolol, Atenolol) Uses: Hypertension, angina, arrhythmias Mechanism: Blocks beta receptors, reducing heart rate and blood pressure Side Effects: Bradycardia, fatigue, hypotension Nursing Implications: Monitor heart rate and blood pressure before administering, caution with asthma patients Calcium Channel Blockers (e.g., Amlodipine, Diltiazem) Uses: Hypertension, angina Mechanism: Inhibits calcium entry, relaxing blood vessels Side Effects: Peripheral edema, constipation Nursing Implications: Monitor blood pressure and heart rate, assess for edema Diuretics (e.g., Furosemide, Spironolactone) Uses: Edema, hypertension Mechanism: Reduces fluid overload by increasing urine output Side Effects: Hypokalemia (with loop diuretics), hyperkalemia (with potassium-sparing diuretics) Nursing Implications: Monitor electrolytes, I&Os, and blood pressure 2. Anticoagulants and Antiplatelets Blood thinners are essential in preventing clot formation and managing thromboembolic disorders. Heparin and Enoxaparin (Lovenox) Uses: DVT prevention, PE treatment Mechanism: Inhibits clotting factors to prevent clot formation Side Effects: Bleeding, thrombocytopenia Nursing Implications: Monitor aPTT (for Heparin), observe for signs of bleeding, use antidote (Protamine Sulfate) if needed Warfarin (Coumadin) Uses: Long-term anticoagulation for DVT, PE, atrial fibrillation Mechanism: Inhibits vitamin K-dependent clotting factors Side Effects: Bleeding Nursing Implications: Monitor INR levels, avoid foods high in vitamin K, antidote is vitamin K Antiplatelets (e.g., Aspirin, Clopidogrel) Uses: Prevents clots in conditions like stroke or heart attack Mechanism: Inhibits platelet aggregation Side Effects: GI bleeding, bruising Nursing Implications: Monitor for bleeding, educate patients on avoiding other NSAIDs 3. Diabetes Medications Diabetes management is a critical area in nursing, and it’s essential to know about different classes of diabetic medications: Insulin (Rapid-Acting, Short-Acting, Long-Acting) Examples: Lispro (rapid-acting), Regular insulin (short-acting), Glargine (long-acting) Uses: Type 1 and 2 diabetes management Mechanism: Lowers blood glucose by promoting cellular glucose uptake Nursing Implications: Monitor blood glucose levels, rotate injection sites, be aware of onset, peak, and duration times to prevent hypoglycemia Oral Hypoglycemics (e.g., Metformin, Glipizide) Uses: Type 2 diabetes management Mechanism: Decreases glucose production in the liver (Metformin), stimulates insulin release (Glipizide) Side Effects: GI upset, hypoglycemia (for sulfonylureas like Glipizide) Nursing Implications: Monitor blood glucose, assess for GI side effects, hold Metformin before contrast dye procedures to prevent lactic acidosis 4. Antibiotics Knowledge of common antibiotics and their side effects is crucial: Penicillins (e.g., Amoxicillin) Uses: Treats bacterial infections like respiratory infections Mechanism: Inhibits cell wall synthesis Side Effects: Allergic reactions, GI upset Nursing Implications: Assess for allergies, take with food to reduce GI upset Cephalosporins (e.g., Ceftriaxone) Uses: Broad-spectrum antibiotic Mechanism: Inhibits cell wall synthesis Side Effects: GI upset, possible cross-allergy with penicillins Nursing Implications: Assess for allergies, monitor for signs of superinfection (e.g., C. difficile) Macrolides (e.g., Azithromycin) Uses: Respiratory infections, skin infections Mechanism: Inhibits protein synthesis Side Effects: GI upset, QT prolongation Nursing Implications: Monitor for arrhythmias, take on an empty stomach if tolerated 5. Pain Medications Both opioid and non-opioid pain relievers are commonly tested. Opioids (e.g., Morphine, Fentanyl) Uses: Moderate to severe pain Mechanism: Binds to opioid receptors, providing pain relief Side Effects: Respiratory depression, constipation, sedation Nursing Implications: Monitor respiratory rate, use naloxone for overdose, educate on constipation prevention NSAIDs (e.g., Ibuprofen, Naproxen) Uses: Mild to moderate pain, inflammation Mechanism: Inhibits COX enzymes, reducing inflammation and pain Side Effects: GI bleeding, kidney impairment Nursing Implications: Take with food, monitor kidney function, assess for GI bleeding 6. Psychiatric Medications Psychiatric drugs require understanding of their therapeutic effects, side effects, and safety measures. SSRIs (e.g., Fluoxetine, Sertraline) Uses: Depression, anxiety Mechanism: Increases serotonin in the brain Side Effects: Weight gain, sexual dysfunction, serotonin syndrome Nursing Implications: Educate on time frame for effectiveness, watch for signs of serotonin syndrome Benzodiazepines (e.g., Lorazepam, Diazepam) Uses: Anxiety, seizures, sedation Mechanism: Enhances GABA activity Side Effects: Sedation, dependence Nursing Implications: Avoid abrupt discontinuation, monitor for respiratory depression, educate on risk of dependence Antipsychotics (e.g., Haloperidol, Risperidone) Uses: Schizophrenia, bipolar disorder Mechanism: Alters dopamine levels Side Effects: Extrapyramidal symptoms, tardive dyskinesia, sedation Nursing Implications: Monitor for EPS, assess mental status, educate on avoiding alcohol 7. Respiratory Medications Respiratory conditions like asthma and COPD require specific medication knowledge. Bronchodilators (e.g., Albuterol) Uses: Asthma, COPD Mechanism: Relaxes bronchial smooth muscles Side Effects: Tachycardia, tremors Nursing Implications: Monitor heart rate, educate on correct inhaler technique Steroids (e.g., Prednisone, Beclomethasone) Uses: Inflammation in asthma or COPD Mechanism: Reduces inflammation Side Effects: Hyperglycemia, increased risk of infection Nursing Implications: Monitor blood sugar, educate on rinsing mouth after inhaled steroids
