A client who had an acute myocardial infarction (MI) is scheduled for percutaneous coronary intervention (PCI). The client asks the nurse about the purpose of this procedure. How should the nurse respond?

"PCI is used to relieve chest pain and reduce inflammation in your heart muscle."

"It involves the placement of a stent in your coronary artery to keep it open and improve blood flow to your heart."

"PCI will help lower your blood pressure and improve your heart's pumping function."

"It is a surgical procedure to bypass blocked coronary arteries and restore blood flow to your heart."

Answer and Explanation

The Correct Answer is B

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 A

Explanation

A) This choice is correct. Engaging in regular physical activity and maintaining a healthy weight are effective strategies for reducing the risk of MI. Physical activity helps improve cardiovascular health, manage weight, and reduce other risk factors like hypertension and diabetes.

B) This choice is incorrect because while limiting saturated fat intake is important for heart health, it is not the most effective approach to lower the risk of MI when compared to engaging in physical activity and maintaining a healthy weight.

C) This choice is incorrect because quitting smoking and reducing alcohol consumption are essential for reducing the risk of MI, but they may not be as effective as regular physical activity and weight management.

D) This choice is incorrect because controlling stress through relaxation techniques and counseling is beneficial for overall well-being, but it may not be the most effective approach to reduce the risk of MI when compared to regular physical activity and weight management. Stress management is still an important aspect of cardiovascular health, but it should be combined with other lifestyle changes for optimal risk reduction.

Questions

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.
