Question 1 of 5
The HCP ordered an angiotensin-converting enzyme (ACE) inhibitor for the client diagnosed with a myocardial infarction. Which statement best explains the rationale for administering this medication to this client?
Correct Answer: A
Rationale: ACE inhibitors reduce afterload and prevent ventricular remodeling, lowering CHF risk post-MI, per ACC/AHA guidelines. BP, contractility, or atherosclerosis are secondary.
Question 2 of 5
You are caring for a hypertensive client with a new order for captopril (Capoten). Which information should the nurse include in client teaching?
Correct Answer: C
Rationale: Avoid the use of salt substitutes. Captopril can cause an accumulation of potassium or hyperkalemia. Clients should avoid the use of salt substitutes, which are generally potassium-based.
Question 3 of 5
A 60-year-old client has been hospitalized for deep vein thrombosis. The client is to be discharged on warfarin (Coumadin) 5 mg PO daily. Which statement that the client makes indicates the best understanding of the medication routine?
Correct Answer: C
Rationale: Warfarin requires regular INR monitoring via blood tests to ensure therapeutic anticoagulation levels.
Question 4 of 5
The 38-year-old client with chronic asthma is prescribed a leukotriene receptor antagonist. Which is the scientific rationale for administering this medication?
Correct Answer: A
Rationale: Leukotriene receptor antagonists (e.g., montelukast) are prophylactic, reducing inflammation to control asthma. They don’t cure, stabilize mast cells, or directly dilate bronchioles.
Question 5 of 5
The client diagnosed with asthma is prescribed the mast cell inhibitor cromolyn. Which statement by the client indicates the need for further teaching?
Correct Answer: D
Rationale: Cromolyn is a prophylactic, not rescue, medication for asthma; using it during wheezing indicates misunderstanding. Pre-exercise use, breath-holding, and rinsing (though less critical) are correct.
