A nurse is preparing to administer blood to a client. Which of the following actions should the nurse take to identify the client? (Select All that Apply.)

A. Initiate cardiopulmonary resuscitation (CPR): CPR is not indicated in this scenario unless the client experiences a cardiac arrest. Chest pain during an exercise stress test does not automatically warrant CPR.

B. Administer sublingual nitroglycerin to allow the client to finish the test: Nitroglycerin is typically used to relieve angina (chest pain) associated with myocardial ischemia. However, in this case, the exercise stress test should be stopped to evaluate the cause of the chest pain before administering nitroglycerin.

C. Stop the test and monitor the client closely: This is the correct action. Chest pain during an exercise stress test may indicate myocardial ischemia (lack of blood flow to the heart muscle), and stopping the test allows for further assessment and evaluation of the client's condition.

D. Administer analgesia and slow the test: Administering analgesia (pain medication) is not appropriate without first determining the cause of the chest pain. Slowing the test may not address the underlying issue and could potentially worsen the client's condition if they are experiencing cardiac-related chest pain.

A. The symptoms indicate an acute coronary episode and should be treated as such:

The client's symptoms, including sudden midsternal chest pain unrelieved with rest and a history of coronary artery disease (CAD), strongly suggest an acute coronary event, such as a myocardial infarction (heart attack). Pale, cool skin can also be indicative of decreased perfusion due to cardiac compromise. Given these critical signs and symptoms, the nurse should interpret this as a potential cardiac emergency and initiate immediate interventions aimed at managing and stabilizing the client's condition.

B. The symptoms indicate angina and should be treated as such:

While angina can present with symptoms such as chest pain, it is typically relieved with rest or nitroglycerin. In contrast, the client in this scenario has midsternal chest pain that is not relieved with rest, which is more indicative of an acute coronary event like a myocardial infarction. Therefore, interpreting the symptoms as angina and treating them as such may not be appropriate given the severity and persistence of the chest pain.

C. Treatment should be determined pending the results of an exercise stress test:

Waiting for the results of an exercise stress test is not appropriate in this scenario, as the client's presentation suggests an acute cardiac event that requires immediate intervention. Exercise stress tests are typically used for diagnostic purposes to assess cardiovascular function under controlled conditions but are not suitable for managing acute coronary episodes or emergencies.

D. The symptoms indicate a pulmonary etiology rather than a cardiac etiology:

While some symptoms, such as shortness of breath or chest pain, can overlap between cardiac and pulmonary conditions, the client's presentation with sudden midsternal chest pain unrelieved with rest, pale cool skin, and a history of CAD strongly suggests a cardiac etiology, specifically an acute coronary event. It is essential to prioritize cardiac assessment and intervention based on the client's symptoms and medical history.
