A client with ST-elevation myocardial infarction (STEMI) is admitted to the emergency department. The healthcare provider orders fibrinolytic therapy. What is the primary purpose of fibrinolytic therapy in this situation?

To reduce heart rate and blood pressure.

To dissolve existing blood clots in coronary arteries.

To stabilize the heart's electrical activity.

To improve oxygen supply to the heart muscle.

Answer and Explanation

The Correct Answer is B

A) This choice is incorrect because fibrinolytic therapy is not used to reduce heart rate and blood pressure. Its primary purpose is to dissolve blood clots that are causing the myocardial infarction.

B) This choice is correct. Fibrinolytic therapy, also known as thrombolytic therapy, is used to break down existing blood clots in coronary arteries during an ST-elevation myocardial infarction (STEMI). By dissolving the clot, blood flow to the heart muscle can be restored and prevent further damage.

C) This choice is incorrect because stabilizing the heart's electrical activity is not the primary purpose of fibrinolytic therapy. It is used to address the mechanical obstruction caused by the clot in coronary arteries.

D) This choice is incorrect because although fibrinolytic therapy does improve blood flow to the heart muscle by dissolving clots, its primary purpose is not to improve oxygen supply directly. Rather, it aims to restore blood flow by eliminating the clot causing the infarction.

Correct Answer is D

Explanation

A) This choice is not the most concerning finding among the options presented. A blood pressure of 130/80 mmHg is within a normal range and does not indicate an immediate risk to the client.

B) This choice is not the most concerning finding among the options presented. A heart rate of 90 beats per minute is within a normal range and does not indicate an immediate risk to the client.

C) This choice is not the most concerning finding among the options presented. An oxygen saturation of 95% on room air is within a normal range and does not indicate an immediate risk to the client.

D) This choice is correct. An elevated ST segment on the electrocardiogram (ECG) is an important sign of an acute myocardial infarction (MI). It indicates myocardial ischemia and injury. The nurse should take immediate action, such as notifying the healthcare provider and implementing appropriate interventions for the client's acute coronary syndrome. Prompt medical intervention is crucial to minimize cardiac damage and improve the client's prognosis.

Questions

A. "Take aspirin at the onset of chest pain." B. "Keep a log of activities that trigger your angina." C. "Limit physical activity to avoid exertion." D. "Use nitroglycerin as needed for chest pain relief."

Correct Answer is D

Explanation

A) This choice is incorrect because while aspirin is important for clients with angina, the priority teaching point is the use of nitroglycerin for chest pain relief during angina episodes.

B) This choice is incorrect because keeping a log of triggers can be helpful for managing angina, but it is not the priority teaching point regarding the immediate relief of chest pain.

C) This choice is incorrect because limiting physical activity to avoid exertion is not the primary management strategy for angina. Moderate exercise, as tolerated, is beneficial for clients with stable angina.

D) This choice is correct. Nitroglycerin is a vasodilator that helps to relax and widen blood vessels, improving blood flow and relieving chest pain during an angina episode. Teaching the client to use nitroglycerin as needed for chest pain relief is a priority in angina management.
