Questions & Verified Answers
1. A patient is prescribed a drug that is a known CYP450 enzyme inducer. What effect will
this have on a co-administered drug that is metabolized by the same enzyme system?
A. The plasma concentration of the second drug will decrease, potentially leading to therapeutic
failure.
B. The plasma concentration of the second drug will increase, leading to toxicity.
C. There will be no change in the metabolism of the second drug.
D. The second drug will become more ionized and be excreted faster by the kidneys.
Answer: A
Rationale: Enzyme inducers increase the rate of drug metabolism, which lowers the plasma
concentration of the substrate drug, often necessitating a dose increase to maintain efficacy.
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. 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 affected by the ‘first-pass effect’?
A. Distribution
B. Metabolism
C. Excretion
D. Absorption
Answer: B
Rationale: The first-pass effect refers to the rapid hepatic metabolism of a drug after oral
administration before it reaches systemic circulation. 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. 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.

3. A patient with heart failure is started on an ACE inhibitor. Which electrolyte abnormality
should the nurse practitioner monitor for most closely?
A. Hypokalemia
B. Hyponatremia
C. Hypocalcemia
D. Hyperkalemia
Answer: D
Rationale: ACE inhibitors block the production of aldosterone, which leads to potassium retention,
putting the patient at risk for hyperkalemia. This knowledge supports safe care and helps the nurse
teach the client and family clearly and simply. Clear teaching improves cooperation and reduces
anxiety. 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.
4. What is the primary mechanism of action of Beta-1 selective blockers like Metoprolol?
A. Decrease heart rate and myocardial contractility
B. Increase peripheral vascular resistance
C. Promote bronchodilation in the lungs
D. Stimulate the release of renin from the kidneys
Answer: A
Rationale: Beta-1 receptors are primarily located in the heart. Blocking them decreases heart rate
(chronotropy) and contractility (inotropy). Exam questions often test whether you can pick the most
practical and safe choice for the client in real situations. Focus on what the nurse can actually do right
now. In practice, this guides the nurse to set priorities and protect the client from harm. Safety,
nutrition, and clear communication are frequent priorities.
