A nurse is caring for a client with a confirmed myocardial infarction (MI) and a history of congestive heart failure (CHF). The client is prescribed a medication to reduce myocardial oxygen demand. Which medication should the nurse expect to administer?

Furosemide.

Metoprolol.

Aspirin.

Nitroglycerin.

Answer and Explanation

The Correct Answer is B

A) This choice is incorrect because furosemide is a loop diuretic used to treat fluid retention and edema in clients with congestive heart failure (CHF), but it does not directly reduce myocardial oxygen demand.

B) This choice is correct. Metoprolol is a beta-blocker that reduces heart rate and blood pressure, resulting in decreased myocardial oxygen demand. It is often prescribed to clients with an MI and a history of CHF to improve cardiac function and reduce the workload on the heart.

C) This choice is incorrect because aspirin is an antiplatelet medication that prevents further clot formation and is commonly prescribed in clients with acute coronary syndrome, including MI. While it is beneficial in the context of MI management, it does not directly reduce myocardial oxygen demand.

D) This choice is incorrect because nitroglycerin is a vasodilator used to relieve chest pain (angina) by dilating blood vessels and increasing blood flow to the heart muscle. While it helps reduce anginal symptoms, it does not directly reduce myocardial oxygen demand as metoprolol does.

Correct Answer is D

Explanation

A) This choice is incorrect because inserting a stent is a part of percutaneous coronary intervention (PCI) and not coronary artery bypass grafting (CABG). CABG involves using blood vessels (grafts) to bypass blocked coronary arteries and restore blood flow to the heart.

B) This choice is incorrect because removing plaque from coronary arteries is not the primary purpose of CABG. CABG involves bypassing blocked arteries rather than removing the plaque.

C) This choice is incorrect because repairing damaged heart valves and improving cardiac function is a different surgical procedure, such as valve repair or replacement surgery. CABG does not address heart valve issues.

D) This choice is correct. Coronary artery bypass grafting (CABG) is a surgical procedure that involves taking a healthy blood vessel from another part of the body and grafting it to the blocked coronary artery. The graft bypasses the blockage, restoring blood flow to the heart and improving myocardial oxygen supply. CABG is used to treat significant coronary artery disease and improve cardiac function in clients with unstable angina or myocardial infarction.

A. Lie down in bed and rest for at least 30 minutes. B. Monitor blood pressure and heart rate every 15 minutes. C. Avoid drinking water or any fluids for an hour. D. Sit or lie down and avoid sudden position changes.

Correct Answer is D

Explanation

A) This choice is incorrect because while rest is essential during an angina episode, lying down in bed for an extended period is not necessary after administering nitroglycerin.

B) This choice is incorrect because monitoring blood pressure and heart rate every 15 minutes is not a standard nursing intervention after nitroglycerin administration. Monitoring vital signs as needed for the client's condition is appropriate.

C) This choice is incorrect because there is no need for the client to avoid drinking water or fluids after taking sublingual nitroglycerin.

D) This choice is correct. After taking sublingual nitroglycerin for chest pain relief, the client should sit or lie down and avoid sudden position changes. Nitroglycerin can cause systemic vasodilation and may lead to orthostatic hypotension, increasing the risk of dizziness or falls if the client stands up abruptly. Taking a seated or lying position reduces this risk and allows the medication to work effectively to relieve chest pain.
