Question 5 of 5
A patient in the clinic reports difficulty tolerating the current ACE inhibitor medication, and questions if another medication could be used. The nurse correctly suspects the prescriber will choose which medication, which affects the renin-angiotensin-aldosterone system?
Correct Answer: B
Rationale: The renin-angiotensin-aldosterone system (RAAS) regulates blood pressure and fluid balance. ACE inhibitors block angiotensin II formation, but if intolerable (e.g., due to cough), an angiotensin II receptor blocker (ARB) like losartan (Choice B) is a common alternative, as it also targets RAAS by blocking angiotensin II receptors. Atenolol (A) is a beta-blocker, not a direct RAAS modulator. Spironolactone (C) is an aldosterone antagonist, affecting RAAS indirectly but less commonly substituted for ACE inhibitors in this context. Adenosine (D) is unrelated to RAAS, used for arrhythmias.
