The test will visualize the flow of blood within your heart.

The test will require you to lie on your left side.

The test will detect abnormal rhythms.

Answer and Explanation

The Correct Answer is D

Rationale:

A. Ejection fraction is typically assessed using echocardiography or other imaging modalities, not electrocardiography.

B. Visualizing the flow of blood within the heart is typically done using imaging modalities such as echocardiography or cardiac catheterization, not electrocardiography.

C. The client's position during an electrocardiogram is usually supine, not specifically on the left side.

D. Electrocardiography is primarily used to detect abnormal rhythms of the heart, such as atrial fibrillation, ventricular tachycardia, or heart block.

Correct Answer is B

Explanation

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.

A. This procedure will detect ventricular thrombi. B. This procedure will determine heart conduction problems. C. This procedure will determine exercise tolerance. D. This procedure will detect blood flow to the distal extremities.

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.
