NURS 180 Week 1 2026 – 200 Exam Questions on Pharmacology Foundations, Drug Safety, Clinical Trials and Medication Administration

This document contains approximately 200 structured exam questions and correct answers for NURS 180 Week 1 (2026), presented across 28 comprehensive pages in detailed Q&A format. The material thoroughly covers foundational pharmacology concepts including pharmacotherapeutics, mechanism of action, pharmacologic versus therapeutic classifications, prototype drug approach, therapeutic index, pharmacokinetics (absorption, distribution, metabolism, excretion), liver biotransformation, half-life considerations, protein binding, and drug metabolism changes in older adults. The document also includes essential dosage conversions (tsp to mL), medication safety principles, and the five rights of medication administration. Extensive coverage is given to drug approval and research processes, including preclinical investigation, Phase I–IV clinical trials, Good Clinical Practice standards, ethical principles (beneficence, respect for persons), informed consent components, placebo and control groups, experimental design, and FDA Modernization Act provisions. Controlled substances and scheduling (Schedule I–V), physical dependence, opioid toxicity and withdrawal, alcohol toxicity management (thiamine, IV fluids, glucose), drug diversion reporting, and safe disposal of medications are also addressed in depth. The guide further explores patient-centered medication teaching, adherence strategies, polypharmacy risks, geriatric pharmacology considerations (first-pass effect, decreased gastric blood flow, altered distribution due to fat and muscle changes, decreased serum albumin), pediatric safety principles including atraumatic care, use of oral syringes for accuracy, and developmental teaching strategies. It also integrates pharmacogenetics concepts such as HLA-B*5701 screening before abacavir, personalized medicine, prodrugs, hepatic enzyme induction effects (e.g., warfarin dosing), synergistic drug interactions, and herbal supplement safety under the Dietary Supplement Health and Education Act (DSHEA). This document is especially suitable for: Pre-licensure nursing students enrolled in NURS 180 Students beginning pharmacology coursework Nursing students preparing for Week 1 pharmacology exams Learners reviewing medication safety and drug approval processes Students strengthening foundational knowledge for NCLEX-style testing It serves as a comprehensive, exam-focused study resource designed to reinforce medication safety, ethical clinical research standards, pharmacokinetic principles, patient education strategies, controlled substance regulations, and evidence-based nursing responsibilities in drug administration.
