A nurse is caring for a female client who has a diagnosis of Cushing syndrome. The client is embarrassed that she is experiencing hirsutism and severe acne. The nurse understands that these manifestations are caused by which of the following?

Excess mineralocorticoids

Excess adrenal androgens

Excess thyroid hormone

Excess glucocorticoids

Answer and Explanation

The Correct Answer is B

A. Excess mineralocorticoids: Mineralocorticoids primarily affect electrolyte and fluid balance. While excess mineralocorticoids can cause hypertension and fluid retention, they are not directly responsible for hirsutism or acne.
B. Excess adrenal androgens: Cushing syndrome can lead to elevated levels of adrenal androgens, which are responsible for hirsutism (excessive hair growth) and acne due to their androgenic effects.
C. Excess thyroid hormone: Thyroid hormone imbalances can affect various body systems, but they are not directly related to the development of hirsutism or acne seen in Cushing syndrome.
D. Excess glucocorticoids: While excess glucocorticoids are characteristic of Cushing syndrome and can cause a range of symptoms, hirsutism and acne are specifically due to excess adrenal androgens rather than glucocorticoids.

Correct Answer is A

Explanation

A. B-type natriuretic peptide (BNP): BNP levels are elevated in heart failure due to increased pressure and stretch in the heart's chambers. It is a key marker used to diagnose and assess the severity of heart failure.
B. Troponin I: This marker is used to diagnose myocardial infarction (heart attack) rather than heart failure. Elevated troponin levels indicate damage to the heart muscle.
C. Blood urea nitrogen (BUN): BUN levels can be elevated in heart failure due to decreased renal perfusion, but it is not as specific for diagnosing heart failure as BNP.
D. Platelet levels: Platelet levels are not directly related to the diagnosis of heart failure. They are more relevant for assessing clotting disorders and other conditions.

A. It is important that you taper off of the corticosteroids you are taking which have caused this disorder. B. You will need to have your adrenal glands removed to reverse your symptoms. C. You will need to begin taking hydrocortisone, and increase your dose during times of stress. D. You will receive glucose checks and sliding-scale insulin until your hormone levels are corrected.

Correct Answer is B

Explanation

A. It is important that you taper off of the corticosteroids you are taking which have caused this disorder: This statement is not applicable because the client has a pituitary adenoma causing Cushing disease, not iatrogenic Cushing syndrome from corticosteroid use.
B. You will need to have your adrenal glands removed to reverse your symptoms: For Cushing disease caused by a pituitary adenoma, treatment typically involves surgical removal of the pituitary tumor, not the adrenal glands.
C. You will need to begin taking hydrocortisone, and increase your dose during times of stress: This is incorrect as hydrocortisone replacement is used for Addison's disease, not for managing Cushing disease.
D. You will receive glucose checks and sliding-scale insulin until your hormone levels are corrected: While glucose monitoring might be necessary due to hyperglycemia, the primary treatment for Cushing disease involves addressing the source of excess cortisol, which is the pituitary adenoma.
