Questions & Verified Answers
1. Which phase of pharmacokinetics is most significantly impacted by the ‘first-pass effect’
during oral administration?
A. Distribution
B. Metabolism
C. Absorption
D. Excretion
Answer: B
Rationale: The first-pass effect refers to the rapid hepatic metabolism of a drug absorbed from the
gastrointestinal tract before it reaches the systemic circulation. 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. A patient with hypoalbuminemia is prescribed a highly protein-bound drug. How should
the clinician adjust the dosage?
A. Increase the dose because there is less protein to transport the drug.
B. Decrease the dose because there will be a higher concentration of free drug.
C. Maintain the dose as albumin does not affect drug efficacy.
D. Switch to an intravenous route to bypass protein binding.
Answer: B
Rationale: Low albumin levels result in fewer binding sites for highly protein-bound drugs, leading to
increased levels of active free drug and potential toxicity; thus, a lower dose is often required. 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

3. Which cytochrome P450 enzyme is responsible for metabolizing approximately 50% of all
clinically used drugs?
A. CYP2D6
B. CYP1A2
C. CYP3A4
D. CYP2C19
Answer: C
Rationale: CYP3A4 is the most abundant cytochrome P450 enzyme in the liver and is involved in the
metabolism of about half of all prescribed medications. 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. 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.
4. If a drug has a half-life of 6 hours, how long will it take for the drug to reach a steady-state
concentration with repeated dosing?
A. 24 to 30 hours
B. 12 to 18 hours
C. 6 to 12 hours
D. 48 to 72 hours
Answer: A
Rationale: Steady state is generally reached after 4 to 5 half-lives. 4 x 6 = 24 hours; 5 x 6 = 30 hours.
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. This is
