Pharmacology Module 1 (2026) – 180 Questions on Drug Forms, Administration Rights, Interactions & Controlled Substances

This document contains approximately 180 comprehensive exam-style questions with correct verified answers for Pharmacology Module 1 (2026). It provides foundational coverage of pharmacology principles including drug classifications (prescription, over-the-counter, social, herbal, street drugs), pharmacokinetics (“what the body does to the drug”), medication forms (tablets, capsules, caplets, enteric-coated, sustained release, transdermal patches, suppositories, syrups, elixirs, suspensions, solutions, ointments, pastes), and legal medication order requirements. Early sections (pages 1–6) emphasize routes of administration, medication composition and absorption, dysphagia, generic vs trade names, and the legal components required in a medication order, including prescriber signature within 48 hours. The document thoroughly reviews the Five (and Six) Rights of Medication Administration, nurse responsibilities (three label checks, allergy verification, expiration checks, two patient identifiers), time windows (within 20 minutes of scheduled time), documentation standards, and high-alert drug verification (S4 and S8 double checks) (pages 12–16). Drug interactions are clearly defined (antagonistic vs synergistic), along with adverse reactions, urticaria, anaphylaxis, beta blockers (-lol), ACE inhibitors (-pril), bronchodilators (-line), and classification of drugs by chemical, generic, and trade names (pages 16–22). Extensive regulatory and safety content includes the Food, Drug, and Cosmetic Act (1938), Durham-Humphrey Amendment (1952), Controlled Substances Act (1970), Schedules I–V definitions, abuse potential, and pregnancy categories (A, B, C, D, X) with risk interpretation (pages 22–26). Practical dosage calculation and measurement systems are also covered, including SI units (meter, kilogram, liter), metric conversions (mcg, mg, g, kg), household conversions (tsp, Tbsp, oz, lb), mEq, International Units, and safe liquid medication measurement devices (pages 27–32). Medication label components, package insert information, dosage strength definition, and decimal movement rules are reinforced for safe administration practice. The structured Q&A format mirrors introductory nursing pharmacology examinations and strengthens medication safety principles, dosage calculation competency, regulatory knowledge, and foundational pharmacologic terminology.
