A nurse is caring for a client admitted with myocardial infarction (MI). The client's blood pressure drops, and the client becomes restless and anxious. What intervention should the nurse initiate first?

Administer oxygen therapy.

Elevate the client's legs.

Obtain a 12-lead electrocardiogram (ECG).

Initiate cardiopulmonary resuscitation (CPR).

Answer and Explanation

The Correct Answer is A

A) This choice is correct. Administering oxygen therapy is the priority intervention when a client with MI experiences a drop in blood pressure and becomes restless and anxious. Oxygen can improve tissue oxygenation and help stabilize the client's condition.

B) This choice is incorrect because elevating the client's legs may be beneficial in certain situations, but it is not the priority when the client is experiencing a drop in blood pressure and restlessness due to MI.

C) This choice is incorrect because obtaining a 12-lead ECG is important for assessing and diagnosing MI, but it is not the priority when the client's condition is deteriorating rapidly.

D) This choice is incorrect because initiating cardiopulmonary resuscitation (CPR) is not indicated in this scenario. The client is still conscious and experiencing symptoms, indicating a need for prompt oxygen administration and further assessment.

Correct Answer is A

Explanation

A) This choice is correct. Measuring troponin levels in the blood is a common initial diagnostic test for evaluating suspected angina pectoris or myocardial infarction (MI). Troponins are specific markers released into the bloodstream when there is cardiac muscle damage, and elevated troponin levels indicate myocardial injury.

B) This choice is incorrect because a stress test is used to assess the heart's response to increased demand and is typically performed after the initial evaluation, such as measuring troponin levels, to confirm the presence of angina or MI.

C) This choice is incorrect because coronary angiography is an invasive procedure used to visualize the coronary arteries and assess for blockages. It is not typically the initial diagnostic test for angina pectoris or MI.

D) This choice is incorrect because cardiac catheterization is an invasive procedure used to measure pressures within the heart and evaluate coronary artery blockages. It is not typically the initial diagnostic test for angina pectoris or MI.

A. "Exercise will help you lose weight and reduce your risk of developing diabetes." B. "It improves blood flow to your heart and can help lower your blood pressure." C. "Exercise is primarily for building muscle strength and improving bone health." D. "It helps you cope with stress and anxiety related to your heart condition."

Correct Answer is B

Explanation

A) This choice is incorrect because while exercise can contribute to weight loss and reduce the risk of diabetes, its primary benefit in cardiac rehabilitation is related to cardiovascular health, specifically improving blood flow to the heart and lowering blood pressure.

B) This choice is correct. Regular exercise in cardiac rehabilitation has significant benefits for the cardiovascular system. It improves blood flow to the heart muscle, enhances collateral circulation, and can help lower blood pressure, all of which are crucial in managing and preventing further complications after an MI.

C) This choice is incorrect because although exercise can help build muscle strength and improve bone health, these are not the primary benefits sought in cardiac rehabilitation. The focus is on cardiovascular health and recovery.

D) This choice is incorrect because while exercise can have positive effects on mental health, such as reducing stress and anxiety, its primary benefit in cardiac rehabilitation is related to cardiovascular health.
