Section 1: Pharmacological Principles (Q1–Q10)
Q1. A nurse is reviewing a medication that is highly protein-bound.
Which finding indicates a potential drug interaction?
A. The client has a low serum albumin level
B. The client has a high serum albumin level
C. The client has normal renal function
D. The client has a normal WBC count
,Answer: A
Rationale: Low serum albumin means fewer protein binding sites,
increasing free (active) drug levels and the risk of toxicity.
Q2. Which statement best describes a drug's onset of action?
A. The time it takes for a drug to reach its minimum effective concentration
B. The time it takes for a drug to be eliminated
C. The time it takes for a drug to be absorbed
D. The time it takes for a drug to reach its peak effect
Answer: A
Rationale: Onset of action is the time required for a drug to reach the
minimum effective concentration (MEC).
Q3. A nurse is teaching a client about a medication that is a prodrug.
Which statement indicates understanding?
A. "The drug must be metabolized by my body to become active."
B. "The drug is active as soon as I swallow it."
C. "The drug is excreted unchanged."
D. "The drug does not need to be metabolized."
Answer: A
Rationale: Prodrugs are inactive until metabolized into their active form
(e.g., clopidogrel, enalapril).
Q4. Which factor most affects drug elimination in an older adult?
A. Decreased renal function
B. Increased gastric acid
C. Increased liver size
D. Increased cardiac output
Answer: A
Rationale: Older adults have decreased renal clearance, leading to drug
accumulation and increased risk of toxicity.
,Q5. A nurse is administering two medications that are both highly
protein-bound. Which effect should the nurse anticipate?
A. Increased therapeutic effect of both drugs
B. Decreased therapeutic effect of both drugs
C. No effect
D. Decreased risk of toxicity
Answer: A
Rationale: Two highly protein-bound drugs compete for binding sites,
increasing free drug levels and therapeutic/toxic effects.
Q6. Which term describes the movement of a drug from the
bloodstream into body tissues?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Answer: B
Rationale: Distribution is the movement of a drug from the bloodstream
into tissues and target organs.
Q7. A nurse is reviewing a medication that is a potent CYP450
inhibitor. Which effect should the nurse anticipate?
A. Increased levels of drugs metabolized by CYP450
B. Decreased levels of drugs metabolized by CYP450
C. No effect on other drugs
D. Increased renal excretion
Answer: A
Rationale: CYP450 inhibitors decrease metabolism of substrate drugs,
increasing their levels and risk of toxicity.
, Q8. Which route of administration has the slowest onset of action?
A. Intravenous
B. Intramuscular
C. Subcutaneous
D. Oral
Answer: D
Rationale: Oral medications have the slowest onset due to the time
required for disintegration, dissolution, and absorption.
Q9. A nurse is administering a medication with a narrow therapeutic
index. Which action is most important?
A. Monitor serum drug levels
B. Administer with food
C. Administer rapidly
D. Use a large-bore needle
Answer: A
Rationale: Narrow therapeutic index drugs (e.g., digoxin, lithium,
phenytoin, warfarin) require serum level monitoring.
Q10. Which statement about first-pass metabolism is accurate?
A. It occurs in the liver after oral absorption
B. It occurs in the kidneys
C. It occurs in the lungs
D. It occurs only with IV medications
Answer: A
Rationale: First-pass metabolism occurs in the liver after a drug is
absorbed from the GI tract and before it reaches systemic circulation.
