Questions & Verified Answers
1. When prescribing a drug that is a strong CYP3A4 inhibitor to a patient already taking a
substrate of that enzyme, the provider should expect which of the following?
A. Decreased plasma levels of the substrate drug
B. Increased plasma levels of the substrate drug
C. Rapid excretion of the substrate drug
D. No change in drug metabolism
Answer: B
Rationale: Inhibition of the CYP450 enzyme responsible for metabolizing a drug (the substrate) leads
to reduced clearance and higher plasma concentrations, increasing the risk of toxicity. 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.
2. According to the Beer’s Criteria, which class of medications should be avoided in elderly
patients due to high risk of orthostatic hypotension and falls?
A. Proton pump inhibitors
B. Alpha-1 blockers for hypertension
C. Biguanides like metformin
D. Selective serotonin reuptake inhibitors
Answer: B
Rationale: Alpha-1 blockers are associated with high rates of orthostatic hypotension in the elderly,
making them high-risk according to the Beer’s Criteria. 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. Remembering this point will help you decide the best nursing action when

3. A patient with a history of heart failure and a reduced ejection fraction is being started on
a Beta-blocker. Which of the following is a primary mechanism of action in this context?
A. Increasing heart rate to improve cardiac output
B. Promoting systemic vasodilation through Alpha-2 stimulation
C. Reducing sympathetic workload and preventing cardiac remodeling
D. Increasing myocardial contractility
Answer: C
Rationale: In heart failure, Beta-blockers are used to protect the heart from excessive sympathetic
stimulation, slowing the progression of remodeling and reducing mortality. 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. 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.
4. Which pharmacological property describes the movement of a drug from its site of
administration into the bloodstream?
A. Distribution
B. Excretion
C. Metabolism
D. Absorption
Answer: D
Rationale: Absorption is the process by which a drug enters the systemic circulation from the site of
administration. 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.
