Final answer:
The nurse would expect an echocardiogram to be prescribed for the obese client experiencing symptoms of palpitations, chronic fatigue, and dyspnea on exertion.
Step-by-step explanation:
The diagnostic procedure that the nurse would expect to be prescribed for the obese client with symptoms of palpitations, chronic fatigue, and dyspnea on exertion is an Echocardiogram.
An echocardiogram is a diagnostic test that uses ultrasound to create images of the heart. It can provide valuable information about the structure and function of the heart, including detecting abnormalities such as enlargement, fluid buildup, or impaired pumping ability.
This procedure is commonly used to evaluate cardiac function in patients with symptoms suggestive of heart disease, like the client in this scenario.
