NUR 372 – Exam 3 Q&A (100+ Questions) – IV Complications, Insulin Types, Fluid Balance, Injections, Med Safety

This expert-verified guide for NUR 372 Exam 3 (2026) includes over 100 high-yield questions and answers, thoroughly covering key nursing procedures and pharmacology topics related to medication administration, IV therapy, insulin management, injection techniques, and fluid/electrolyte imbalances. Designed for BSN and ABSN students, it’s ideal for unit exams, clinical check-offs, and NCLEX prep. The medication administration content includes essential principles such as safe handling of vesicant medications (e.g., vancomycin, phenytoin, potassium), drug interactions with insulin (hypoglycemic: sulfonylureas, beta-blockers; hyperglycemic: glucocorticoids, thiazide diuretics), and details on cardiac glycosides like digoxin and their effects on contractility. Insulin therapy is extensively reviewed, detailing onset, peak, and duration of: Rapid-acting insulin: lispro, aspart, glulisine Short-acting (Regular) Intermediate-acting (NPH) Long-acting: glargine, detemir (peakless, 20–24 hr duration) IV therapy and complications cover signs, causes, and management of: Infiltration: cool site, edema, sluggish flow Phlebitis: streaking, redness, tenderness Hematoma: bruising, ecchymosis Thrombophlebitis: hard cordlike vein Cellulitis and extravasation: localized redness or tissue damage from vesicants All include appropriate interventions like warm compresses, site removal, culture collection, and elevation. Injection techniques are summarized by route, gauge, and volume: Intradermal: 26–28G, 0.5 in, 0.1 mL Subcutaneous: 25–30G, 3/8–1 in, up to 1 mL Intramuscular: 20–25G, 1–1.5 in, up to 3 mL Fluid and electrolyte balance topics include: ECF vs ICF composition (Na⁺, Cl⁻ vs K⁺, phosphate) Hypervolemia (e.g., from CHF, cirrhosis): signs like edema, crackles, JVD Hypovolemia (e.g., due to burns, hemorrhage): signs like hypotension, tachycardia, confusion Detailed nursing considerations such as fall precautions, I&O tracking, IV therapy, compression socks, and sodium restriction Best for students in: BSN or ABSN programs studying med-surg, pharmacology, IV therapy, and fluid balance Preparing for NUR 372 Exam 3, clinicals, or NCLEX-RN fundamentals Needing fast recall on insulin types, injection sites, IV complications, and safety This focused guide merges essential clinical nursing skills with safety-centered pharmacologic knowledge, promoting excellence in both academic and hands-on settings.
