A nurse is educating a client about the preparations needed before completing a cardiac stress test. Which of the following statements by the client would indicate the teaching was effective?

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.

Rationale:

A. Nitroglycerin is typically taken as needed for angina symptoms, not routinely before going to bed.

B. Taking one tablet at the first indication of chest pain is the correct instruction for using nitroglycerin to relieve angina symptoms.

C. While multiple doses of nitroglycerin may be needed during an acute angina attack, they should be spaced at least 5 minutes apart, not every 15 minutes.

D. Nitroglycerin is not typically used to lower blood pressure. It is primarily used to relieve angina symptoms by dilating blood vessels and improving blood flow to the heart.
