Answer to Question 1

ANS: B
The principal disorder of posterior pituitary hypofunction is diabetes insipidus. The anterior pituitary produces hormones such as growth hormone, thyroid-stimulating hormone, adrenocorticotropic hormone, gonadotropin, prolactin, and melanocyte-stimulating hormone. The adrenal cortex produces aldosterone, sex hormones, and glucocorticoids. The adrenal medulla produces catecholamines.

Answer to Question 2

ANS: A
Injections are best given at bedtime to more closely approximate the physiologic release of GH. Before or after meals and on arising in the morning are times that do not mimic the physiologic release of the hormone.
