Questions & Verified Answers
1. A patient is prescribed a drug that is a known CYP3A4 inhibitor. What effect will this have
on a second drug that is a substrate of the same enzyme?
A. Decreased serum levels of the substrate drug
B. Increased serum levels and potential toxicity of the substrate drug
C. Reduced bioavailability of the inhibitor drug
D. Increased renal clearance of the substrate drug
Answer: B
Rationale: CYP450 inhibitors block the metabolism of substrate drugs, leading to accumulation and
increased risk of toxicity. Knowing the reason behind the correct answer makes it easier to rule out the
wrong options quickly. Look for the choice that protects the client and matches the priority need.

2. Which pharmacokinetic process is most significantly affected by a patient’s serum
albumin levels?
A. Distribution
B. Absorption
C. Metabolism
D. Excretion
Answer: A
Rationale: Distribution is affected by protein binding; drugs that are highly protein-bound rely on
albumin levels to determine the free, active fraction of the drug. In practice, this guides the nurse to set
priorities and protect the client from harm. Safety, nutrition, and clear communication are frequent
priorities. This knowledge supports safe care and helps the nurse teach the client and family clearly
and simply. Clear teaching improves cooperation and reduces anxiety.

3. When prescribing for a geriatric patient, which physiological change most significantly
impacts drug clearance?
A. Increased gastric pH
B. Decreased glomerular filtration rate (GFR)
C. Increased total body water
D. Increased hepatic blood flow
Answer: B
Rationale: A decline in renal function (decreased GFR) is the most important physiological change
affecting drug excretion in the elderly. Understanding this helps the nurse notice early warning signs
and act before the problem gets worse. Early action often prevents bigger complications for the client.

4. According to the Pregnancy and Lactation Labeling Rule (PLLR), what information is now
required in drug labeling?
A. Clinical considerations for prescribing to pregnant and lactating individuals
B. A simple letter category (A, B, C, D, X)
C. A statement that all drugs are unsafe during the first trimester
D. Mandatory animal testing data only
Answer: A
Rationale: The PLLR replaced letter categories with detailed summaries of risks and clinical
considerations for pregnancy, lactation, and reproductive potential. This is important because the
nurse must choose the action that keeps the client safest while still meeting their basic needs. Always
think about safety first when answering these questions. Understanding this helps the nurse notice
early warning signs and act before the problem gets worse. Early action often prevents bigger
complications for the client.
