A nurse is preparing to administer vancomycin 500 mg PO daily divided into four equal doses. The amount available is vancomycin 125 mg capsules. How many capsules should the nurse administerwitheachdose?

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 test is noninvasive, and nothing will be inserted into the client's body: Transthoracic echocardiography (TTE) is a noninvasive procedure that uses ultrasound waves to create images of the heart. It involves placing a transducer on the chest wall to capture images of the heart's structure and function. The nurse should inform the client that no instruments or devices will be inserted into their body during the test.

B. The client will remain on bed rest for 1 to 2 hours after the test: This statement is not typically accurate for a TTE procedure. After a TTE, clients can usually resume their normal activities without any specific bed rest requirements, unless otherwise specified by the healthcare provider based on individual circumstances.

C. The client's pain will be managed aggressively during the procedure: TTE is generally a painless procedure that does not require aggressive pain management. The client may feel slight discomfort from the transducer's pressure on the chest, but it is typically well tolerated without the need for pain medication.

D. The test will provide a detailed profile of the heart's electrical activity: While echocardiography provides detailed images of the heart's structure and function, including information about blood flow and valve function, it does not directly assess the heart's electrical activity. For evaluating electrical activity, other tests such as electrocardiography (ECG or EKG) would be used.
