INSTANT PDF DOWNLOAD—This comprehensive study guide is specifically designed for Galen College of Nursing students preparing for NUR 210 Principles of Pharmacology Exam 4 for the 2026/2027 academic year. Based on verified exam materials from top-selling student resources, this resource contains expertly verified practice questions and 100% correct answers with detailed rationales to help you master core pharmacology concepts and achieve a top score (Grade A+). This comprehensive guide covers all major topics tested on NUR 210 Exam 4 : Cephalosporins & Antibiotic Therapy : Cefepime priority nursing intervention—monitor for signs of superinfection (superinfection is a common adverse effect) . IV cephalosporins administered over 30-45 minutes, not 2 hours; full regimen typically 10 days. For draining wounds, priority intervention is to obtain culture and sensitivity (C&S) before initiating antibiotics . Patient teaching includes reporting signs of superinfection such as mouth ulcers or discharge . MRSA & Vancomycin : Treatment of choice for methicillin-resistant Staphylococcus aureus (MRSA) is vancomycin . Monitor for adverse effects including nephrotoxicity (BUN/creatinine, urine output) and ototoxicity (hearing loss, tinnitus) . IV administration too fast causes Red-Man Syndrome; give slowly over 1-2 hours . Aminoglycosides (Gentamicin) : Peak levels drawn 45-60 minutes after drug administration; trough levels drawn immediately before next dose . Monitor for ototoxicity (tinnitus, hearing loss) and nephrotoxicity . Sulfonamides (TMP-SMZ/Bactrim) : Highest priority teaching—increase fluid intake to at least 2000 mL/day to prevent crystalluria . TMP-SMZ is synergistic combination; primarily used for urinary tract infections (UTIs) . Increases hypoglycemic effect of sulfonylureas and anticoagulant effect of warfarin; avoid antacids (decrease absorption) . Tetracyclines (Doxycycline) : Avoid calcium, iron, and antacids (decrease absorption) . Causes permanent teeth staining—not given to children under 8 years . Monitor for stomatitis (mouth sores) . Macrolides (Azithromycin) : Monitor for hepatotoxicity; educate patient to use sunblock and protective clothing during sun exposure (photosensitivity) . Antifungals : Nystatin for oral candidiasis (thrush)—swish and swallow, gargle if in throat . Fluconazole for systemic fungal infections; monitor for liver/renal failure; avoid alcohol . Antivirals (Acyclovir) : Gingival hyperplasia can occur with prolonged use; oral hygiene should be performed several times daily . Increase fluid intake to maintain hydration and prevent crystalluria; begin at first sign of outbreak . Urinary Tract Medications : Nitrofurantoin (Macrodantin)—warn patient not to drive (drowsiness); avoid antacids; urine may turn harmless brown color; do not crush tablets . Phenazopyridine (Pyridium)—urinary analgesic for pain and burning; anticipate red-orange urine discoloration . Influenza Vaccine : Eggs are used to produce the flu vaccine; assess for egg allergy before administration . Other Key Drugs : Metronidazole (Flagyl)—avoid alcohol (disulfiram-like reaction) . Ciprofloxacin (fluoroquinolone)—monitor for anaphylaxis, angioedema, Stevens-Johnson syndrome . Epoetin alfa—monitor hemoglobin; do not give if Hgb 11 . Filgrastim—increases WBC count . Sample Questions Include : "Which nursing intervention has the highest priority for the patient taking cefepime?" → Monitor patient for signs/symptoms of superinfection (superinfection is a common adverse effect of antibiotics) "A patient enters the ED with a draining wound. Once admitted, the priority nursing intervention is to:" → Culture the wound (priority is obtaining culture and sensitivity testing before antibiotics) "A patient is admitted with MRSA. The nurse anticipates administration of which drug?" → Vancomycin (Vancocin) (treatment of choice for MRSA) "What is the highest priority teaching for a patient taking TMP-SMZ?" → Increase fluid intake to at least 2000 mL/day (prevents crystalluria) "Why do patients get yeast infections after antibiotics?" → Yeast infections are common when normal body flora are disrupted "What should the nurse ask before administering influenza vaccine?" → "Are you allergic to eggs?" (eggs used to produce the vaccine) "What should the nurse teach a patient taking Nitrofurantoin?" → Warn patient not to drive a motor vehicle (may cause drowsiness) All questions include complete rationales based on current evidence-based practice, pharmacology standards, and Galen College curriculum requirements .
