Topic 1: Fundamentals of Pharmacology and Drug
Classifications (Questions 1–20)
1. Which term refers to the study of how a drug moves through the body, including
absorption, distribution, metabolism, and excretion?
A. Pharmacodynamics
B. Pharmacokinetics
C. Toxicology
D. Bioavailability
Correct Answer: B. Pharmacokinetics
Rationale: Pharmacokinetics involves the movement of drugs within the body and includes four
main processes: absorption, distribution, metabolism, and excretion.
2. A nurse administering a beta-blocker understands the drug works primarily by:
A. Increasing heart rate and cardiac output
B. Decreasing heart rate and blood pressure
C. Promoting bronchodilation and airway clearance
D. Stimulating insulin release
Correct Answer: B. Decreasing heart rate and blood pressure
Rationale: Beta-blockers block the beta-adrenergic receptors in the heart, reducing heart rate
and blood pressure.

3. Which class of medications is typically prescribed to reduce cholesterol levels in the blood?
A. Diuretics
B. Statins
C. Antiplatelets
D. Antacids
Correct Answer: B. Statins
Rationale: Statins inhibit the enzyme HMG-CoA reductase, essential for cholesterol synthesis,
thereby lowering LDL cholesterol levels.
4. A patient has been prescribed furosemide. The nurse should monitor which electrolyte
imbalance?
A. Hypernatremia
B. Hypokalemia
C. Hyperkalemia
D. Hypermagnesemia
Correct Answer: B. Hypokalemia
Rationale: Furosemide is a loop diuretic that increases the excretion of potassium, potentially
leading to hypokalemia.
5. The 'first-pass effect' refers to:
A. The first dose given to a patient
B. A drug's elimination half-life
C. Metabolism of a drug in the liver before reaching systemic circulation
D. The primary drug interaction in the stomach
Correct Answer: C. Metabolism of a drug in the liver before reaching systemic circulation
Rationale: The first-pass effect is the liver's metabolizing action that can significantly reduce the
amount of active drug before it enters systemic circulation.

6. Which of the following is classified as a Schedule II controlled substance?
A. Diazepam
B. Acetaminophen
C. Morphine
D. Diphenhydramine
Correct Answer: C. Morphine
Rationale: Schedule II drugs like morphine have high abuse potential but also legitimate
medical use under strict regulation.
7. What is the primary action of ACE inhibitors in treating hypertension?
A. Stimulating the heart rate
B. Blocking the conversion of angiotensin I to angiotensin II
C. Enhancing sodium absorption
D. Constricting blood vessels
Correct Answer: B. Blocking the conversion of angiotensin I to angiotensin II
Rationale: ACE inhibitors prevent the formation of angiotensin II, a potent vasoconstrictor,
thereby reducing blood pressure.
8. What nursing consideration is most important when administering digoxin?
A. Monitor liver function
B. Assess bowel sounds
C. Check apical pulse before administration
D. Measure respiratory rate
Correct Answer: C. Check apical pulse before administration
Rationale: Digoxin slows heart rate, so it's crucial to assess the apical pulse for at least one
minute. If below 60 bpm, hold the dose.
