Correct Answer: B

Rationale: Following a myocardial infarction (MI), ACE inhibitors are commonly prescribed due to their proven benefit in reducing mortality and improving outcomes post-MI. These medications help by decreasing the workload of the heart, preventing remodeling of the heart chambers, and improving survival rates. While ACE inhibitors may have effects on potassium levels, the primary reason for their prescription post-MI is their mortality-reducing properties.

Correct Answer: A

Rationale: Beta blockers are the first-line medication prescribed to prevent angina pain. They work by reducing the heart rate and blood pressure, decreasing the heart's demand for oxygen. This helps in preventing angina attacks by improving blood flow to the heart. Alpha blockers, calcium channel blockers, and organic nitrates are also used in angina treatment but are typically considered after beta blockers.

Correct Answer: D

Rationale: In cases of chronic angina where initial treatment has not been successful, Ranolazine (Ranexa) is often prescribed. This medication helps by reducing the frequency of angina episodes. Atenolol, Nitroglycerin, and Sildenafil are also used in angina management but Ranolazine is more specifically indicated in cases of refractory angina where other treatments have failed.

Correct Answer: A

Rationale: In the setting of a suspected myocardial infarction (MI), the priority medications to administer as soon as possible include aspirin (ASA) and possibly morphine to manage pain and anxiety. Clopidogrel (Plavix) is not typically administered immediately in the emergency setting for MI management. Metoprolol (Lopressor) is indicated after aspirin administration and stabilization of the patient. Therefore, in this scenario, clopidogrel should NOT be given as a first-line medication for a suspected MI.
