A client is undergoing a stress test to evaluate possible myocardial ischemia. What is the primary purpose of this test?

To assess for the presence of atherosclerotic plaques.

To measure cardiac biomarker levels in the blood.

To evaluate the heart's response to increased demand.

To visualize the coronary arteries for blockages.

Answer and Explanation

The Correct Answer is C

A) This choice is incorrect because a stress test is not primarily used to assess for the presence of atherosclerotic plaques. It is used to evaluate the heart's response to increased demand and identify exercise-induced changes in the ECG, which may indicate myocardial ischemia.

B) This choice is incorrect because a stress test does not measure cardiac biomarker levels in the blood. Cardiac biomarkers like troponin are typically measured through blood tests to diagnose myocardial infarction (MI).

C) This choice is correct. The primary purpose of a stress test is to evaluate the heart's response to increased demand, such as physical exercise or the administration of medication that simulates exercise. During the test, the client's heart rate, blood pressure, and ECG are monitored for signs of ischemia.

D) This choice is incorrect because a stress test is not used to visualize the coronary arteries for blockages. It is a non-invasive test primarily used to assess the heart's functional capacity.

Correct Answer is D

Explanation

A) This choice is incorrect because while aspirin is important for clients with angina, the priority teaching point is the use of nitroglycerin for chest pain relief during angina episodes.

B) This choice is incorrect because keeping a log of triggers can be helpful for managing angina, but it is not the priority teaching point regarding the immediate relief of chest pain.

C) This choice is incorrect because limiting physical activity to avoid exertion is not the primary management strategy for angina. Moderate exercise, as tolerated, is beneficial for clients with stable angina.

D) This choice is correct. Nitroglycerin is a vasodilator that helps to relax and widen blood vessels, improving blood flow and relieving chest pain during an angina episode. Teaching the client to use nitroglycerin as needed for chest pain relief is a priority in angina management.

A. "PCI is used to relieve chest pain and reduce inflammation in your heart muscle." B. "It involves the placement of a stent in your coronary artery to keep it open and improve blood flow to your heart." C. "PCI will help lower your blood pressure and improve your heart's pumping function." D. "It is a surgical procedure to bypass blocked coronary arteries and restore blood flow to your heart."

Correct Answer is B

Explanation

A) This choice is incorrect because while PCI can indirectly relieve chest pain by restoring blood flow to the heart, its primary purpose is not to reduce inflammation in the heart muscle.

B) This choice is correct. Percutaneous coronary intervention (PCI) involves the insertion of a catheter with a balloon at the tip into the blocked coronary artery. The balloon is inflated to compress the plaque and open the artery, and then a stent is placed to keep the artery open and improve blood flow to the heart.

C) This choice is incorrect because PCI's primary purpose is not to lower blood pressure but to restore blood flow to the heart by treating coronary artery blockages.

D) This choice is incorrect because the description provided is more characteristic of coronary artery bypass grafting (CABG) surgery, not PCI.
