Questions & Verified Answers
1. A patient with chronic kidney disease (CKD) requires an antihypertensive. Why are ACE
inhibitors particularly indicated in this population despite the risk of hyperkalemia?
A. They increase the glomerular filtration rate significantly.
B. They decrease the risk of metabolic acidosis.
C. They are the only class that does not require renal dose adjustment.
D. requires an antihypertensive. Why are ACE inhibitors particularly indicated in this population
despite the risk of hyperkalemia?
Answer: D
Rationale: ACE inhibitors reduce proteinuria and slow the progression of CKD by dilating the efferent
arteriole, thereby reducing intraglomerular pressure. 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.
2. When prescribing a drug that is a strong Cytochrome P450 3A4 inhibitor to a patient
already taking a substrate of the same enzyme, what is the expected outcome?
A. Increased plasma levels and potential toxicity of the substrate.
B. Decreased plasma levels and therapeutic failure of the substrate.
C. Accelerated metabolism of the substrate drug.
D. No change in substrate levels due to competitive inhibition.
Answer: A
Rationale: Inhibitors decrease the metabolic activity of CYP enzymes, leading to reduced clearance
and increased concentrations of substrate drugs. 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. 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.

3. A patient is diagnosed with New York Heart Association (NYHA) Class III Heart Failure.
Which medication is contraindicated due to the risk of exacerbating fluid retention?
A. Class III Heart Failure. Which medication is contraindicated due to the risk of exacerbating fluid
retention?
B. Carvedilol
C. Lisinopril
D. Spironolactone
Answer: A
Rationale: TZDs like pioglitazone cause fluid retention and are contraindicated in patients with
symptomatic heart failure. 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.
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. What is the primary mechanism of action of Metformin in the management of Type 2
Diabetes?
A. Stimulating insulin secretion from pancreatic beta cells.
B. Inhibiting hepatic glucose production and improving insulin sensitivity.
C. Increasing glucose reabsorption in the proximal tubule.
D. Slowing the absorption of carbohydrates in the GI tract.
Answer: B
Rationale: Metformin works by decreasing hepatic gluconeogenesis and increasing peripheral
glucose uptake by improving insulin sensitivity. 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
