BIOD 351 Exam 1 2026/2027 | 40 Questions & Answers | Pharmacokinetics, Pharmacodynamics, Drug Interactions & Dosage Calculations | Portage Learning

This BIOD 351 Exam 1 2026/2027 study document contains 40 pharmacology questions with correct answers across 8 pages, providing focused exam preparation on foundational principles of drug therapy. The material covers pharmacokinetics, pharmacodynamics, adverse drug effects, receptors, agonists and antagonists, dosage forms, routes of administration, drug metabolism, drug interactions, medication safety, controlled substances, FDA drug approval, and dosage calculations. The document is identified on its first page as Portage BIOD 351 Exam 1 and combines true/false, matching, short-answer, calculation, and applied patient-scenario questions. A central section examines pharmacokinetics and the ADME process—absorption, distribution, metabolism, and excretion. Students review bioavailability, factors affecting absorption, distribution through the bloodstream, highly perfused organs, hepatic drug metabolism and renal drug elimination. The questions also test drug half-life and steady state, including comparison of drugs with different half-lives and the principle that repeated half-lives are required for substantial drug elimination. The document also provides targeted review of pharmacodynamics and drug-receptor interactions. Questions distinguish agonists, partial agonists and antagonists and explore how drugs exert effects through receptors, enzymes and other cellular processes. Students additionally review enzyme inhibition, synergistic drug interactions and age-related changes in pharmacokinetics, including the potential for decreased metabolism to prolong drug action in older patients. Another important area is drug formulation and routes of administration. The exam covers tablets, capsules, troches, suppositories, syrups and enteric-coated preparations while distinguishing oral, topical and parenteral administration. Questions connect the route of administration to drug absorption and onset of action, helping students understand how dosage form and administration method influence the delivery of medications. Later questions move into drug interactions, cytochrome P450 metabolism, medication regulation and safety. Students review enzyme-related interactions, renal excretion interactions, FDA drug approval, postmarketing surveillance, medication errors, prescribing authority, Schedule II controlled substances, drug tolerance and drug dependence. The final page adds clinically relevant weight-based dosage calculations, requiring conversion from pounds to kilograms and calculation of milligram and tablet doses. The document is particularly useful for students who need a concise review of introductory pharmacology before BIOD 351 Exam 1, especially because it combines terminology with practical patient scenarios and medication calculations. Some statements in the source should nevertheless be checked against current course materials and authoritative pharmacology guidance; for example, the FDA replaced the former A/B/C/D/X pregnancy-letter categories with the Pregnancy and Lactation Labeling Rule framework. The document should therefore be treated as exam-preparation material rather than a substitute for current prescribing or clinical guidance. Relevant Students: BIOD 351 students, Portage Learning students, nursing prerequisite students, pre-nursing students, nursing students taking introductory pharmacology, allied-health students, healthcare students reviewing pharmacokinetics and pharmacodynamics, and students preparing for exams involving medication administration, drug interactions, ADME principles and dosage calculations.
