Correct Answer: C

Rationale: Calcium channel blockers and beta blockers should be used with caution together because they can both suppress heart function, potentially leading to bradycardia, heart block, or heart failure. NSAIDs and cardiac glycosides do not have significant interactions with calcium channel blockers in the same way, so they are not typically a cause for concern when combined.

Correct Answer: A

Rationale: Thrombolytic medications are used to dissolve blood clots. In the case of a hemorrhagic stroke, where there is bleeding in the brain, the use of thrombolytics can worsen the condition by increasing bleeding. Therefore, hemorrhagic strokes should not be treated with thrombolytic medications.

Correct Answer: D

Rationale: The correct medical term for impaired blood flow in the coronary arteries is Coronary heart disease. This condition is characterized by a narrowing or blockage of the coronary arteries, leading to reduced blood flow to the heart muscle. Myocardial infarction (choice A) refers to a heart attack, which occurs when blood flow to a part of the heart is blocked. Angina pectoris (choice B) is chest pain or discomfort that occurs when the heart muscle doesn't receive enough oxygen-rich blood. Cerebrovascular accident (choice C) is the medical term for a stroke, which occurs when blood flow to a part of the brain is interrupted.

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: C

Rationale: Angina is primarily treated with calcium channel blockers, organic nitrates, and beta blockers. Alpha blockers are not commonly used in the treatment of angina. Calcium channel blockers help dilate blood vessels, decreasing the workload on the heart. Organic nitrates relax and widen blood vessels, improving blood flow and reducing the heart's workload. Beta blockers reduce the heart rate and blood pressure, decreasing the heart's demand for oxygen. Alpha blockers are more commonly used to treat conditions like hypertension and benign prostatic hyperplasia.
