Question 1 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 2 of 5

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.

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.
