Answer to Question 1

ANS: D
Beta blockers can delay awareness of and response to hypoglycemia by masking signs associated with stimulation of the sympathetic nervous system (eg, tachycardia, palpitations) that hypoglycemia normally causes. Furthermore, beta blockade impairs glycogenolysis, which is one means by which the body can counteract a fall in blood glucose; beta blockers, therefore, can worsen insulin-induced hypoglycemia.
Propranolol does not cause insulin resistance.
The incidence of DKA is not increased by concurrent use of propranolol and insulin.
Insulin requirements are not increased because of receptor blocking by propranolol.

Answer to Question 2

ANS: B
A variety of drugs, such as NSAIDs, can intensify hypoglycemic responses to most sulfonylureas and therefore should be avoided by patients taking sulfonylureas.
Use of a sulfonylurea does not predispose patients to infection or increased emotional stress or cause them to reduce their physical activity level.
