Answer to Question 1

ANS: A
Sulfonylureas stimulate the pancreas to secrete more insulin. They also diminish glucose production and metabolism of insulin by the liver. The net effect is a normalization of insulin and glucose levels. Sulfonylureas decrease glucose production and hepatic metabolism of insulin.

Answer to Question 2

ANS: A
Beta-adrenergic blocking agents (e.g., propranolol, timolol, nadolol, pindolol) may mask many symptoms of hypoglycemia. Lipodystrophy does not increase the absorption of insulin. Infection does not decrease the need for insulin. Excessive exercise does not increase the need for insulin.
