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 B

Explanation

A) This choice is incorrect because chest pain relieved by rest and nitroglycerin is characteristic of stable angina, not an MI. Stable angina is triggered by physical exertion or emotional stress and is usually relieved by rest and nitroglycerin use.

B) This choice is correct. Diaphoresis (profuse sweating) and nausea are clinical manifestations commonly associated with an MI but not usually seen in stable angina. These symptoms are a result of the sympathetic nervous system's response to the heart muscle's decreased oxygen supply during an MI.

C) This choice is incorrect because chest pain triggered by emotional stress is characteristic of stable angina, not an MI. Emotional stress can cause vasospasms in the coronary arteries, leading to angina episodes.

D) This choice is incorrect because shortness of breath and wheezing may occur in both stable angina and MI, especially if the heart's pumping ability is compromised. These symptoms are not specific to MI and can also be seen in other cardiac and respiratory conditions.

A. "PCI is used to relieve chest pain and reduce inflammation in your heart muscle." B. "It involves the placement of a stent in your coronary artery to keep it open and improve blood flow to your heart." C. "PCI will help lower your blood pressure and improve your heart's pumping function." D. "It is a surgical procedure to bypass blocked coronary arteries and restore blood flow to your heart."

Correct Answer is B

Explanation

A) This choice is incorrect because while PCI can indirectly relieve chest pain by restoring blood flow to the heart, its primary purpose is not to reduce inflammation in the heart muscle.

B) This choice is correct. Percutaneous coronary intervention (PCI) involves the insertion of a catheter with a balloon at the tip into the blocked coronary artery. The balloon is inflated to compress the plaque and open the artery, and then a stent is placed to keep the artery open and improve blood flow to the heart.

C) This choice is incorrect because PCI's primary purpose is not to lower blood pressure but to restore blood flow to the heart by treating coronary artery blockages.

D) This choice is incorrect because the description provided is more characteristic of coronary artery bypass grafting (CABG) surgery, not PCI.
