Question 1 of 5
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?
Correct Answer: B
Rationale: The 24-hour cortisol urine study (
B) measures cortisol levels to confirm Cushing syndrome, characterized by excess cortisol. Radioactive iodine uptake (
A) is for thyroid disorders. ACTH stimulation test (
C) assesses adrenal insufficiency, not Cushing syndrome. Edrophonium test (
D) diagnoses myasthenia gravis, unrelated to Cushing syndrome.
Question 2 of 5
A nurse is providing dietary teaching for a client who has Graves' disease. Which of the following statements made by the client indicates a need for further teaching by the nurse?
Correct Answer: D
Rationale: Six full meals (
D) is excessive; smaller, frequent, high-calorie meals are better for Graves' disease. Protein and carbohydrates (
A), avoiding caffeine (
B), and high-fiber diet (
C) are appropriate.
Question 3 of 5
A client complaining of weight gain and acne undergoes laboratory testing, which reveals elevated cortisol levels and hyperglycemia. The client has no prior medical history, and does not take any medications. After further testing and imaging to determine the cause of the elevated cortisol levels, the client is diagnosed with Cushing disease caused by a pituitary adenoma. Which of the following statements should the nurse include when teaching the client about this diagnosis?
Correct Answer: B
Rationale: Cushing disease from a pituitary adenoma requires surgical removal of the pituitary tumor, not adrenal glands (
B). Tapering corticosteroids (
A) is irrelevant as the client isn't taking them. Hydrocortisone (
C) is for Addison's disease. Glucose checks (
D) are secondary to addressing the tumor.
Question 4 of 5
A client seen in the clinic with shortness of breath and fatigue is being evaluated for a possible diagnosis of heart failure. Which laboratory result will be the most useful for diagnosing heart failure?
Correct Answer: A
Rationale: BNP (
A) is the most specific marker for heart failure, elevated due to cardiac pressure and volume overload. Troponin I (
B) indicates myocardial infarction. BUN (
C) may be elevated in heart failure but is less specific. Platelet levels (
D) are unrelated to heart failure diagnosis.
Question 5 of 5
A nurse is providing education to a client who has Graves' disease and who will be returning home after receiving their first dose of radioactive iodine therapy. Which of the following information should the nurse include?
Correct Answer: B
Rationale: Radioactive iodine therapy emits radiation, requiring avoidance of pregnant women and children for 7 days (
B). Repeat therapy (
A) depends on response, not a fixed schedule. Corticosteroids (
C) aren't needed. The therapy reduces thyroid hormone (
D), not increases it.
