The 38-year-old client with chronic asthma is prescribed a leukotriene receptor antagonist. Which is the scientific rationale for administering this medication?
- A. This medication is used prophylactically to control asthma.
- B. This medication will cure the client's chronic asthma.
- C. It will stabilize mast cell activities and reduce asthma attacks.
- D. It will cause the bronchioles to dilate and increase the airway.
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.

You are caring for a hypertensive client with a new order for captopril (Capoten). Which information should the nurse include in client teaching?
- A. Avoid green leafy vegetables
- B. Restrict fluids to 1000 cc/day
- C. Avoid the use of salt substitutes

- A. Atropine.
- B. Amiodarone.

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?
- A. It will help prevent the development of congestive heart failure.
- B. This medication will help decrease the client's blood pressure.
- C. ACE inhibitors increase the contractility of the heart muscle.
- D. They will help decrease the development of atherosclerosis.
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.
