Correct Answer is A

Explanation

Rationale:

A. A transesophageal echocardiogram (TEE) is a specialized echocardiographic procedure that provides detailed images of the heart, including the atria and ventricles. It is particularly useful for detecting ventricular thrombi (blood clots) that may not be visualized as well with transthoracic echocardiography.

B. While an echocardiogram can provide information about heart function, including conduction problems, a TEE is not typically used specifically for this purpose.

C. Exercise tolerance is typically assessed through exercise stress testing or other exercise- related procedures, not with a TEE.

D. Blood flow to the distal extremities is not directly assessed with a TEE. This procedure primarily focuses on evaluating cardiac structure and function.

A. Clopidogrel B. Clonidine C. Hydralazine D. Nifedipine E. Gemfibrozil

Correct Answer is ["B","C"]

Explanation

Rationale:

A. Clopidogrel is an antiplatelet medication used to prevent blood clots, and it is not associated with orthostatic hypotension.

B. Clonidine is an antihypertensive medication that can cause orthostatic hypotension, particularly when changing positions from lying to standing.

C. Hydralazine is an antihypertensive medication that can cause orthostatic hypotension, particularly at higher doses.

D. Nifedipine, a calcium channel blocker, is generally associated with a risk of hypotension; however, it is not specifically indicated as a common cause of orthostatic hypotension.

E. Gemfibrozil is a lipid-lowering medication and is not associated with orthostatic hypotension.
