A client who recently had an MI is instructed to participate in cardiac rehabilitation. The client asks the nurse about the benefits of exercise in the program. How should the nurse respond?

"Exercise will help you lose weight and reduce your risk of developing diabetes."

"It improves blood flow to your heart and can help lower your blood pressure."

"Exercise is primarily for building muscle strength and improving bone health."

"It helps you cope with stress and anxiety related to your heart condition."

Answer and Explanation

The Correct Answer is B

A) This choice is incorrect because while exercise can contribute to weight loss and reduce the risk of diabetes, its primary benefit in cardiac rehabilitation is related to cardiovascular health, specifically improving blood flow to the heart and lowering blood pressure.

B) This choice is correct. Regular exercise in cardiac rehabilitation has significant benefits for the cardiovascular system. It improves blood flow to the heart muscle, enhances collateral circulation, and can help lower blood pressure, all of which are crucial in managing and preventing further complications after an MI.

C) This choice is incorrect because although exercise can help build muscle strength and improve bone health, these are not the primary benefits sought in cardiac rehabilitation. The focus is on cardiovascular health and recovery.

D) This choice is incorrect because while exercise can have positive effects on mental health, such as reducing stress and anxiety, its primary benefit in cardiac rehabilitation is related to cardiovascular health.

Correct Answer is C

Explanation

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.

A. "Beta-blockers help dilate your blood vessels, improving blood flow to your heart." B. "It reduces your cholesterol levels and prevents the formation of plaques in your arteries." C. "Beta-blockers lower your blood pressure and decrease the workload of your heart." D. "It prevents blood clots from forming in your coronary arteries and causing another MI."

Correct Answer is C

Explanation

A) This choice is incorrect because beta-blockers do not directly dilate blood vessels. They primarily work by blocking the effects of adrenaline on the heart and blood vessels, leading to decreased heart rate and reduced blood pressure.

B) This choice is incorrect because beta-blockers do not directly affect cholesterol levels or prevent the formation of plaques in arteries. Their primary action is on the cardiovascular system, particularly the heart and blood pressure.

C) This choice is correct. Beta-blockers are commonly prescribed after an MI to reduce the workload of the heart and lower blood pressure. By blocking the effects of adrenaline, they help slow down the heart rate and reduce the force of contraction, thereby decreasing myocardial oxygen demand and improving the heart's efficiency.

D) This choice is incorrect because beta-blockers do not directly prevent blood clot formation in coronary arteries. Anticoagulant or antiplatelet medications are used to reduce the risk of clot formation in individuals at high risk for recurrent heart attacks.
