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
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 B
Explanation
A. Levothyroxine replacement test: This test is used to assess the thyroid's response to synthetic thyroid hormone and is not used to differentiate types of hyperthyroidism.
B. Radioactive iodine uptake (RAIU) test: This test measures the thyroid gland's ability to absorb iodine, which helps differentiate Graves' disease (characterized by increased uptake) from other forms of hyperthyroidism, such as thyroiditis (which may show decreased uptake).
C. Adrenocorticotropic hormone (ACTH) stimulation test: This test is used to evaluate adrenal function and is not relevant for diagnosing or differentiating forms of hyperthyroidism.
D. Subtotal thyroidectomy: This is a surgical procedure rather than a diagnostic test and would not be used to differentiate between types of hyperthyroidism.
