A client with unstable angina is prescribed heparin therapy. The client asks the nurse about the purpose of this medication. How should the nurse respond?

"Heparin is used to dissolve blood clots in your coronary arteries and restore blood flow to your heart."

"It helps relax your blood vessels and improve blood flow to your heart muscle."

"Heparin is an anticoagulant that prevents further clot formation in your coronary arteries."

"It is a pain reliever used to reduce chest discomfort during episodes of angina."

Answer and Explanation

The Correct Answer is C

A) This choice is incorrect because heparin does not directly dissolve existing blood clots in coronary arteries. It is used to prevent further clot formation and growth.

B) This choice is incorrect because heparin's primary action is not to relax blood vessels. It is an anticoagulant that inhibits clot formation.

C) This choice is correct. Heparin is an anticoagulant medication used to prevent further clot formation in coronary arteries and reduce the risk of complications in clients with unstable angina.

D) This choice is incorrect because heparin is not a pain reliever. It does not directly address chest discomfort during angina episodes; its role is in preventing and managing thrombosis.

Correct Answer is C

Explanation

A: Oxygen does not directly dilate coronary arteries; medications such as nitrates are responsible for this effect.
B: While oxygen aids in metabolic processes, it does not directly affect the heart's pumping efficiency in the context of angina pectoris.
C: Oxygen therapy increases the oxygen saturation of the blood, which can help alleviate symptoms like shortness of breath and chest pain associated with angina by ensuring that the heart muscle receives sufficient oxygen to function properly.
D: Oxygen therapy is not a treatment for preventing clot formation; this is typically managed with anticoagulant medications.

A. To assess for the presence of atherosclerotic plaques. B. To measure cardiac biomarker levels in the blood. C. To evaluate the heart's response to increased demand. D. To visualize the coronary arteries for blockages.

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.
