A nurse is caring for a client who has hypokalemia, hyperglycemia, and hypertension. A diagnosis of Cushing syndrome is suspected. Which of the following tests would the nurse anticipate the health care provider will order to help confirm the diagnosis of Cushing syndrome?

Radioactive iodine uptake test

24-hour cortisol urine study

Adrenocorticotropic hormone (ACTH) stimulation test

Edrophonium (Tensilon) test

Answer and Explanation

The Correct Answer is B

A. Radioactive iodine uptake test: This test is used to assess thyroid function and diagnose thyroid disorders, such as hyperthyroidism. It is not used to diagnose Cushing syndrome.
B. 24-hour cortisol urine study: This test measures cortisol levels in the urine over a 24-hour period and is commonly used to diagnose Cushing syndrome by evaluating elevated cortisol production.
C. Adrenocorticotropic hormone (ACTH) stimulation test: This test evaluates adrenal function and is typically used to assess adrenal insufficiency rather than Cushing syndrome.
D. Edrophonium (Tensilon) test: This test is used to diagnose myasthenia gravis, not Cushing syndrome. It evaluates the effect of the medication on muscle strength.

Correct Answer is D

Explanation

A. "I will include protein and carbohydrates in every meal": This is appropriate for a client with Graves' disease. A balanced diet with adequate protein and carbohydrates helps meet increased caloric needs due to hypermetabolism.
B. "I will avoid caffeinated beverages": This is a correct statement. Clients with Graves' disease should avoid caffeine as it can exacerbate symptoms like tremors and palpitations.
C. "I will eat a high-fiber diet": This is beneficial for maintaining gastrointestinal health. Hyperthyroidism can cause increased bowel movements, so a high-fiber diet helps prevent diarrhea.
D. "I will eat six full meals per day, with snacks in between": This indicates a need for further teaching. While frequent meals may be needed, "six full meals" can be excessive. Instead, a high-calorie, nutrient-dense diet with smaller, more frequent meals may be recommended to address increased metabolic demands without overloading the digestive system.

A. I will need to wear a medical alert bracelet at all times. B. I will need to hold my hydrocortisone dose if I have an infection. C. I will take my hydrocortisone tablets twice a day. D. I will need to eat a high-sodium diet.

Correct Answer is B

Explanation

A. I will need to wear a medical alert bracelet at all times: This statement is correct. Clients with Addison's disease should wear a medical alert bracelet to inform healthcare providers of their condition in case of an emergency, as it could impact treatment decisions.
B. I will need to hold my hydrocortisone dose if I have an infection: This statement indicates a need for additional teaching. Clients with Addison's disease should not hold their hydrocortisone dose if they have an infection. In fact, they may need to increase their dose during periods of stress or illness to manage their condition effectively.
C. I will take my hydrocortisone tablets twice a day: This statement is correct. Hydrocortisone is typically taken in divided doses to mimic the natural release of cortisol from the adrenal glands.
D. I will need to eat a high-sodium diet: This statement is correct. Clients with Addison's disease often need to increase their sodium intake, as they may have difficulties retaining sodium due to adrenal insufficiency.
