A client with acute myocardial infarction (MI) is prescribed aspirin. The client asks the nurse about the purpose of this medication. How should the nurse respond?

"Aspirin helps dilate your coronary arteries and increase blood flow to your heart."

"It prevents blood clot formation and reduces the risk of further blockages in your coronary arteries."

"Aspirin lowers your blood pressure and helps your heart pump more efficiently."

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

Answer and Explanation

The Correct Answer is B

A) This choice is incorrect because aspirin does not directly dilate coronary arteries. Aspirin's primary action in MI management is its antiplatelet effect, which prevents platelets from clumping together and forming blood clots in coronary arteries, reducing the risk of further blockages.

B) This choice is correct. Aspirin is commonly prescribed during an acute MI to prevent blood clot formation and reduce the risk of further blockages in the coronary arteries. It is a crucial medication in the management of acute coronary syndrome.

C) This choice is incorrect because aspirin's primary action is not to lower blood pressure or improve cardiac pumping efficiency. These actions are typically achieved through other medications, such as beta-blockers or ACE inhibitors, in the management of MI.

D) This choice is incorrect because while aspirin is used to relieve pain and reduce inflammation, its primary role in MI management is its antiplatelet effect, as mentioned earlier.

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.

A. "Coronary angiography will measure the levels of cardiac biomarkers in your blood." B. "It is a stress test that evaluates your heart's response to increased demand." C. "The test involves injecting dye into your coronary arteries to visualize any blockages." D. "Coronary angiography will assess your heart's function using sound waves."

Correct Answer is C

Explanation

A) This choice is incorrect because measuring the levels of cardiac biomarkers in the blood is not the purpose of coronary angiography. Cardiac biomarkers are measured through blood tests to diagnose conditions like myocardial infarction (MI).

B) This choice is incorrect because a stress test evaluates the heart's response to increased demand and is different from coronary angiography.

C) This choice is correct. Coronary angiography is an invasive procedure that involves injecting a contrast dye into the coronary arteries. The dye allows visualization of the coronary arteries and identifies any blockages or narrowing that may be causing angina or other cardiac symptoms.

D) This choice is incorrect because assessing the heart's function using sound waves is characteristic of an echocardiogram, not coronary angiography.
