• INTRODUCTION

This assessment is designed to strengthen the pharmacology knowledge and clinical
reasoning expected of professional nursing students. The questions assess foundational
principles, medication safety, pharmacokinetics, pharmacodynamics, drug classifications,
routes of administration, adverse effects, interactions, patient education, and nursing
responsibilities. Multiple-choice questions are used to evaluate both knowledge and the
ability to apply pharmacologic principles to realistic patient situations. Emphasis is placed on
understanding why medications produce therapeutic and adverse effects rather than
memorizing isolated facts. Scenario-based items encourage safe decision-making,
prioritization, interpretation of patient findings, and appropriate nursing action. The material
is intended for focused examination preparation and comprehensive review.
SECTION ONE: QUESTIONS 1–100
Question 1. Which statement best describes pharmacokinetics?
A. What the drug does to the body
B. What the body does to the drug
C. How a drug binds to a receptor
D. How therapeutic effects are evaluated
Correct Answer: B. What the body does to the drug
,Explanation: Pharmacokinetics describes the movement of a drug through the body,
commonly summarized as absorption, distribution, metabolism, and excretion (ADME).
Pharmacodynamics describes the effects of the drug on the body.
Question 2. Which process describes movement of a medication from its site of
administration into the bloodstream?
A. Distribution
B. Metabolism
C. Absorption
D. Excretion
Correct Answer: C. Absorption
Explanation: Absorption is the movement of a drug from the administration site into
systemic circulation. The extent and rate of absorption depend on factors such as route,
formulation, blood flow, and drug characteristics.
Question 3. Which route provides essentially 100% bioavailability?
A. Oral
B. Subcutaneous
C. Intravenous
D. Rectal
Correct Answer: C. Intravenous
Explanation: Intravenous administration delivers the drug directly into systemic circulation,
so the administered dose is considered completely bioavailable. Other routes may have
incomplete absorption or first-pass metabolism.
Question 4. What is the primary significance of the first-pass effect?
A. It increases renal excretion of all medications.
B. It causes a drug to bind immediately to plasma proteins.
C. It allows a medication to bypass hepatic metabolism.
D. It can reduce the amount of orally administered drug reaching systemic circulation.
Correct Answer: D. It can reduce the amount of orally administered drug reaching systemic
circulation.
Explanation: Drugs absorbed from the gastrointestinal tract may travel through the portal
circulation to the liver before reaching systemic circulation. Hepatic metabolism can
therefore reduce the amount of active drug available systemically.
Question 5. A medication has a half-life of 8 hours. Approximately how much of the original
drug remains after 16 hours?
, A. 75%
B. 50%
C. 25%
D. 12.5%
Correct Answer: C. 25%
Explanation: One half-life leaves 50% of the drug. After two half-lives, half of the remaining
50% is eliminated, leaving 25%.
Question 6. Which pharmacokinetic process is primarily responsible for chemically altering
many medications?
A. Absorption
B. Distribution
C. Metabolism
D. Filtration
Correct Answer: C. Metabolism
Explanation: Metabolism chemically modifies drugs, often making them more water-soluble
for elimination. The liver is the major site of drug metabolism, although other tissues can
contribute.
Question 7. Which organ is the major site of drug excretion?
A. Heart
B. Kidneys
C. Pancreas
D. Spleen
Correct Answer: B. Kidneys
Explanation: The kidneys are the primary organs responsible for eliminating many
medications and their metabolites through urine. Renal impairment can therefore cause
drug accumulation.
Question 8. A medication is highly protein bound. Which patient condition could increase
the amount of free drug in circulation?
A. Increased albumin concentration
B. Decreased albumin concentration
C. Increased urine output
D. Increased gastric acidity
Correct Answer: B. Decreased albumin concentration
