NU150 Exam 3 Study Guide (2026) | 300+ Practice Questions & Verified Answers | Anti-Infective Drugs, Pain Management, Gastrointestinal Pharmacology & Autonomic Nervous System | Galen College of Nursing

Prepare for NU150 Exam 3 at Galen College of Nursing with this comprehensive 2026 study guide, featuring 300+ exam-style practice questions with verified answers and detailed rationales covering the essential principles of anti-infective therapy, pain management, gastrointestinal pharmacology, autonomic nervous system medications, and perioperative nursing care. Designed to strengthen clinical reasoning, pharmacologic knowledge, medication safety, and evidence-based nursing interventions, this resource closely reflects the format and complexity of NU150 examinations while preparing students for clinical practice and NCLEX-style testing. This study guide provides in-depth coverage of antibiotics and anti-infective medications, including penicillins, cephalosporins, tetracyclines, sulfonamides, fluoroquinolones, nitrofurantoin, ciprofloxacin, aminoglycosides, antitubercular medications (isoniazid and rifampin), culture and sensitivity testing, bacterial resistance, broad-spectrum antibiotics, superinfections, Clostridioides difficile infection, thrush, crystalluria, nephrotoxicity, hepatotoxicity, ototoxicity, photosensitivity, tendon rupture, antibiotic allergies, anaphylaxis, medication administration, and patient education. The guide emphasizes safe antibiotic use, infection management, and nursing interventions to prevent complications while promoting antimicrobial stewardship. The resource also offers comprehensive review of pain management and gastrointestinal pharmacology, including opioid analgesics, morphine, meperidine, naloxone, acetaminophen, NSAIDs, aspirin, celecoxib, local anesthetics, lidocaine, proton pump inhibitors (omeprazole), H2 receptor antagonists, antacids, laxatives, stool softeners, anticholinergics, cholinergic medications, atropine, scopolamine, bethanechol, preoperative medications, postoperative care, patient-controlled analgesia (PCA), pain assessment, respiratory depression, urinary retention, constipation, gastrointestinal bleeding, gastroesophageal reflux disease (GERD), peptic ulcer disease, osteoporosis risk with long-term PPI use, electrolyte imbalances, and medication antidotes. Each verified answer reinforces critical nursing concepts required for safe medication administration and successful examination performance. Additionally, this study guide reviews autonomic nervous system pharmacology, parasympathetic and sympathetic nervous system functions, seizure precautions, perioperative nursing care, aspiration prevention, anesthesia considerations, medication contraindications, pharmacologic classifications, adverse drug reactions, nursing priorities, NCLEX-style clinical scenarios, prioritization, and patient education strategies. The material integrates pharmacology with practical nursing decision-making to improve clinical competence and examination readiness. This study guide is ideal for NU150 students, Galen College of Nursing students, Fundamentals of Nursing students, Pharmacology students, Practical Nursing (PN/LPN) students, Associate Degree Nursing (ADN) students, Bachelor of Science in Nursing (BSN) students, pre-nursing students, Registered Nursing (RN) students, and learners preparing for NCLEX-RN or NCLEX-PN examinations.
