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 A

Explanation

A) This choice is correct. The sudden onset of chest pain lasting for 30 minutes is a typical clinical manifestation of myocardial infarction (MI). The duration and intensity of chest pain are important indicators that suggest an acute cardiac event.

B) This choice is incorrect because chest discomfort lasting for a few days may be more characteristic of unstable angina, not an MI. Unstable angina is also a serious condition that requires prompt medical attention, but it is not synonymous with MI.

C) This choice is incorrect because chest pain that comes and goes, lasting only a few seconds at a time, is not typical of an MI. Such symptoms may indicate other non-cardiac conditions or stable angina.

D) This choice is incorrect because a similar episode of chest pain a few months ago is not indicative of the current acute event. The nurse should focus on the client's current symptoms and their acute presentation to determine the appropriate interventions.

A. "Oxygen reduces chest pain by dilating your coronary arteries." B. "Oxygen helps your heart pump blood more effectively." C. "Oxygen increases your oxygen levels and relieves shortness of breath." D. "Oxygen prevents further clot formation in your coronary arteries."

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.
