INTRODUCTION
This comprehensive NURS 615 pharmacology assessment is designed to strengthen the
knowledge and clinical reasoning required for advanced nursing pharmacotherapy. The
questions assess foundational pharmacology, mechanisms of action, pharmacokinetics,
pharmacodynamics, safe prescribing, adverse effects, drug interactions, monitoring, patient
education, and application of medications to realistic clinical situations. Multiple-choice
questions are used to test both factual knowledge and the ability to distinguish closely
related concepts, interpret clinical information, and select appropriate therapeutic
approaches. Emphasis is placed on understanding why an answer is correct so that learners
can apply pharmacologic principles rather than rely solely on memorization. The material is
intended as structured examination practice and study preparation, not as a reproduction of
confidential or unreleased examination questions.
SECTION ONE: QUESTIONS 1–100
Question 1. Which statement best describes pharmacokinetics?
A. What a drug does to the body
B. What the body does to a drug
,C. How a drug binds to its receptor
D. How a drug produces its therapeutic effect
Correct Answer: B. What the body does to a drug
Explanation: Pharmacokinetics describes the movement of drugs through the body,
including absorption, distribution, metabolism, and excretion. Pharmacodynamics describes
what the drug does to the body.
Question 2. Which pharmacokinetic process describes movement of a drug from its site of
administration into the systemic circulation?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Correct Answer: A. Absorption
Explanation: Absorption is the movement of a drug from its administration site into the
bloodstream. The extent and rate of absorption can be affected by route, formulation, blood
flow, and other factors.
Question 3. Which organ is the principal site of metabolism for many medications?
A. Heart
B. Spleen
C. Liver
D. Pancreas
Correct Answer: C. Liver
Explanation: The liver contains numerous metabolic enzymes, particularly cytochrome P450
enzymes, that transform many drugs into metabolites that can subsequently be eliminated.
Question 4. Which organ is primarily responsible for renal excretion of many drugs and their
metabolites?
A. Lung
B. Kidney
C. Stomach
D. Thyroid
Correct Answer: B. Kidney
Explanation: The kidneys eliminate many drugs through glomerular filtration, tubular
secretion, and tubular reabsorption. Renal impairment can therefore increase exposure to
drugs that depend heavily on renal clearance.
, Question 5. A drug has a half-life of 8 hours. Approximately how long would it take for the
drug concentration to fall to 25% of its original concentration, assuming first-order
elimination?
A. 4 hours
B. 8 hours
C. 12 hours
D. 16 hours
Correct Answer: D. 16 hours
Explanation: After one half-life, 50% remains. After two half-lives, 25% remains. Therefore,
two 8-hour half-lives equal 16 hours.
Question 6. Which characteristic generally increases passive diffusion of a drug across cell
membranes?
A. High lipid solubility
B. High molecular weight
C. Permanent ionization
D. Strong plasma protein binding
Correct Answer: A. High lipid solubility
Explanation: Lipid-soluble, relatively nonionized drugs generally cross lipid membranes more
readily by passive diffusion.
Question 7. What is bioavailability?
A. The percentage of drug bound to plasma proteins
B. The fraction of an administered dose that reaches systemic circulation unchanged
C. The amount of drug eliminated by the kidneys
D. The maximum concentration of a drug
Correct Answer: B. The fraction of an administered dose that reaches systemic circulation
unchanged
Explanation: Bioavailability refers to the fraction of an administered dose that reaches
systemic circulation in an unchanged form. Intravenous administration has essentially
complete bioavailability.
Question 8. Which route completely bypasses first-pass hepatic metabolism?
A. Oral
B. Enteral feeding tube
C. Intravenous
D. Rectal
