Answer to Question 1

ANS: C
Bronze or brownish hyperpigmentation of the skin, mucous membranes, and hair occurs when there are very high levels of ACTH. The pigmentation changes associated with Cushing syn-drome and Addison disease are not due to increased levels of cortisol or hypersensitivity of mel-anocytes. Aldosterone affects fluid balance.

Answer to Question 2

ANS: A, B, C, E
Symptoms of hypoparathyroidism include tetany, Chvostek and Trousseau signs, dry (not oily) skin, and loss of body and scalp hair.
