Answer to Question 1

ANS: A
Thyroid hormones act to increase the metabolic rate of body tissues, promote gluconeogenesis, and increase the utilization and mobilization of glycogen stores. They also stimulate protein syn-thesis, cell growth, and differentiation, and aid in development of the central nervous system.

Answer to Question 2

ANS: B
Beta blockers should not be used if possible by diabetic patients. They elevate blood glucose lev-els by increasing hepatic glycogenolysis mediated by receptors. They also mask the sympathetic nervous system symptoms of hypoglycemia.
