Questions & Verified Answers
1. What is the term for the process by which a drug moves from its site of administration into
the blood?
A. Distribution
B. Absorption
C. Metabolism
D. Excretion
Answer: B
Rationale: Absorption is the movement of a drug from its site of administration into the blood. Distribution is the
movement through the body, metabolism is the enzymatic alteration of drug structure, and excretion is the
removal of drugs from the body. This is an important clinical concept because selecting the correct answer (B)
requires understanding both the pathophysiology and the practical nursing implications.
2. Which pharmacokinetic phase is primarily affected in a patient with severe liver disease?
A. Absorption
B. Excretion
C. Distribution
D. Metabolism
Answer: D
Rationale: The liver is the primary site for drug metabolism. If liver function is impaired, the body’s ability to
break down drugs is decreased, potentially leading to toxicity. Applying this knowledge in clinical settings
supports safe, evidence-based practice and improves patient outcomes.
3. A drug has a half-life of 4 hours. If 100 mg is administered, how much of the drug will remain
in the body after 12 hours?
A. 50 mg
B. 25 mg
C. 12.5 mg
D. 6.25 mg
Answer: C
Rationale: After 4 hours (1 half-life), 50 mg remains. After 8 hours (2 half-lives), 25 mg remains. After 12 hours
(3 half-lives), 12.5 mg remains. Recognizing this principle allows the nurse to prioritize care, anticipate
complications, and provide accurate patient education. Exam questions often test the ability to distinguish this
concept from closely related distractors, making a clear rationale essential for mastery.

4. Which route of administration provides 100% bioavailability?
A. Oral (PO)
B. Intramuscular (IM)
C. Subcutaneous (SC)
D. Intravenous (IV)
Answer: D
Rationale: IV administration bypasses absorption barriers and the first-pass effect of the liver, delivering the full
dose directly into the systemic circulation. This is an important clinical concept because selecting the correct
answer (D) requires understanding both the pathophysiology and the practical nursing implications.
Recognizing this principle allows the nurse to prioritize care, anticipate complications, and provide accurate
patient education.
5. What is the primary purpose of a ‘loading dose’?
A. To reduce the risk of allergic reactions
B. To reach therapeutic levels more quickly
C. To minimize the first-pass effect
D. To prevent drug-drug interactions
Answer: B
Rationale: A loading dose is a large initial dose given to achieve a plateau or therapeutic level in the blood
more rapidly than with maintenance doses alone. Exam questions often test the ability to distinguish this
concept from closely related distractors, making a clear rationale essential for mastery. Applying this knowledge
in clinical settings supports safe, evidence-based practice and improves patient outcomes.
6. What does the term ‘narrow therapeutic index’ imply about a drug?
A. The drug is very safe and requires no monitoring.
B. The difference between a therapeutic dose and a toxic dose is small.
C. The drug is only effective for a very narrow range of diseases.
D. The drug has a very short half-life.
Answer: B
Rationale: Drugs with a narrow therapeutic index require close monitoring because the margin between
effectiveness and toxicity is very slim. This is an important clinical concept because selecting the correct
answer (B) requires understanding both the pathophysiology and the practical nursing implications.
Recognizing this principle allows the nurse to prioritize care, anticipate complications, and provide accurate
patient education.
