Questions & Verified Answers
1. A patient with a high Volume of Distribution (Vd) for a specific drug would most likely
require which of the following regarding dosing?
A. A higher loading dose to reach therapeutic plasma concentrations
B. A lower loading dose due to high plasma protein binding
C. A shorter dosing interval to prevent toxicity
D. Immediate discontinuation if the drug is hydrophilic
Answer: A
Rationale: A high Vd indicates the drug is widely distributed into tissues rather than staying in the
plasma. Therefore, a larger loading dose is often needed to achieve the target plasma concentration.
In practice, this guides the nurse to set priorities and protect the client from harm. Safety, nutrition, and
clear communication are frequent priorities. In practice, this guides the nurse to set priorities and

2. Which cytochrome P450 enzyme is responsible for the metabolism of the largest number
of clinically used drugs, and is frequently involved in drug-drug interactions?
A. CYP2D6
B. CYP1A2
C. CYP2C19
D. CYP3A4
Answer: D
Rationale: CYP3A4 is the most abundant CYP enzyme in the liver and is responsible for metabolizing
approximately 50% of all prescribed medications. Clear understanding of this concept improves both
test performance and everyday clinical judgment. Practice applying it to short case scenarios to lock
the idea in place. 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. A patient is prescribed an ACE inhibitor for hypertension. Which electrolyte abnormality
should the provider monitor most closely?
A. Hyperkalemia
B. Hypokalemia
C. Hyponatremia
D. Hypercalcemia
Answer: A
Rationale: ACE inhibitors block the conversion of angiotensin I to angiotensin II, leading to decreased
aldosterone secretion. Decreased aldosterone reduces potassium excretion, potentially causing
hyperkalemia. 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. 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.
4. Which of the following describes the mechanism of action of Sacubitril/Valsartan
(Entresto) in heart failure management?
A. Inhibition of the sodium-potassium pump
B. Blockade of Beta-1 receptors and stimulation of Alpha-2 receptors
C. Inhibition of neprilysin and blockade of angiotensin II receptors
D. Direct stimulation of B-type natriuretic peptide (BNP) synthesis
Answer: C
Rationale: Sacubitril is a neprilysin inhibitor that increases natriuretic peptides, while Valsartan is an
ARB that blocks the RAAS system. 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 important because the nurse must choose the action that keeps the
