A client with aortic regurgitation is experiencing dyspnea and chest pain with activity. The nurse knows that the cause of the symptoms can be best determined by which diagnostic test?
A) Radionuclide scan
B) Electrocardiogram (ECG)
C) Transesophageal echocardiogram (TEE)
D) Magnetic resonance imaging (MRI)
A
Feedback:
Because the symptoms occur with activity, a radionuclide scan could compare the blood flow through the heart at rest and during activity, giving valuable information about the severity of the diseased valve. ECG, TEE, and MRI are diagnostic tests used in the diagnosis of cardiac disease but less specific for exercise evaluation.
