Questions & Verified Answers
1. A patient is prescribed a drug that is a known CYP3A4 inducer. How will this most likely
affect a co-administered drug that is a substrate of the same enzyme?
A. The substrate drug’s plasma concentration will decrease.
B. The substrate drug’s half-life will be prolonged.
C. The substrate drug’s plasma concentration will increase.
D. The substrate drug will become more toxic.
Answer: A
Rationale: Enzyme inducers increase the metabolic activity of CYP450 enzymes, leading to faster
breakdown and lower plasma levels of substrate drugs. 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 of the following describes the ‘steady state’ of a drug, and when is it typically
reached?
A. When the drug is completely eliminated; usually after 2 half-lives.
B. When the drug reaches its peak concentration; usually after 1 half-life.
C. When the amount of drug absorbed equals the amount excreted; usually after 4 to 5 half- lives.
D. When the drug’s therapeutic index is at its highest; usually after 10 half-lives.
Answer: C
Rationale: Steady state occurs when the rate of drug administration equals the rate of elimination,
typically achieved after 4 to 5 half-lives. 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.
Remembering this point will help you decide the best nursing action when similar questions appear on
the exam. Link the answer to the client’s current condition and risk level.

3. A 68-year-old patient is prescribed a medication listed on the Beers Criteria. What is the
primary purpose of this list?
A. To identify drugs that are most cost-effective for geriatric patients.
B. To identify medications that are safe for use in all age groups.
C. To list medications that require prior authorization from Medicare.
D. To identify medications that are potentially inappropriate for older adults.
Answer: D
Rationale: The Beers Criteria identifies medications that may be inappropriate or carry higher risks for
adults aged 65 and older. 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. 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. Which FDA Pregnancy Category indicates that studies in animals or humans have
demonstrated fetal abnormalities, and the risk clearly outweighs any possible benefit?
A. Category B
B. Category X
C. Category D
D. Category C
Answer: B
Rationale: Category X drugs are contraindicated in women who are or may become pregnant
because the risks of fetal harm clearly outweigh potential benefits. This knowledge supports safe care
and helps the nurse teach the client and family clearly and simply. Clear teaching improves
cooperation and reduces anxiety. 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.
