Answer to Question 1

ANS: C
Taking oral antidiabetic agents (sulfonylurea) with sulfonamides increases the hypoglycemic effect. Sulfonylureas do not increase the incidence of headaches, hypertension, or superinfection when taken with sulfonamides. Examples of antidiabetic sulfonylurea medications are glipizide, glimepride, glyburide, tolaamide, and tolbutamide.

Answer to Question 2

ANS: B
The combination drug is used to decrease bacterial resistance to sulfonamides. It does not broaden the spectrum, improve the taste, or decrease toxicity.
