Rationale 1: ACE inhibitors can raise potassium levels.
Rationale 2: The ACE inhibitors, captopril (Capoten) and lisinopril (Prinivil, Zestril), have also been found to reduce mortality following MI. These drugs are most effective when therapy is started within 1 or 2 days after the onset of symptoms.
Rationale 3: ACE inhibitors are not always prescribed in combination with beta blockers and calcium channel blockers.
Rationale 4: ACE inhibitors lower blood pressure, and would treat hypertension, not hypotension.
Global Rationale: The ACE inhibitors, captopril (Capoten) and lisinopril (Prinivil, Zestril), have also been found to reduce mortality following MI. These drugs are most effective when therapy is started within 1 or 2 days after the onset of symptoms. "This medication will lower your potassium level" is incorrect because ACE inhibitors can raise potassium levels. "ACE inhibitors are always prescribed with a beta blocker and calcium channel blocker following an MI" is incorrect because ACE inhibitors are not always prescribed in combination with beta blockers and calcium channel blockers. "This medication will treat your hypotension" is incorrect because ACE inhibitors lower blood pressure, and would treat hypertension, not hypotension.
