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."
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 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.
Correct Answer is C
Explanation
A) This choice is incorrect because sharp, stabbing pain is not typically associated with angina pectoris. It may be more characteristic of conditions like pleuritis or musculoskeletal pain.
B) This choice is incorrect because constant, burning pain is not typical of angina pectoris. It may be associated with conditions like heartburn or gastroesophageal reflux disease (GERD).
C) This choice is correct. Angina pectoris is often described as a crushing or pressure-like pain in the chest, which can be triggered by exertion or emotional stress. The pain may also radiate to the neck, jaw, or left arm.
D) This choice is incorrect because radiating pain to the left arm is associated with both angina pectoris and myocardial infarction (MI), but it is not specific enough to differentiate between the two conditions.
