Answer to Question 1

Ans: A, B, C, E
Feedback:
Beta blockers (atenolol), calcium channel blockers (amlodipine), hydantoins (phenytoin), and thyroid agents (levothyroxine), among others, can result in decreased hypoglycemic effects of sulfonylureas (glyburide).

Answer to Question 2

Ans: D
Feedback:
The nurse should observe for increased hypoglycemic effect in the client as the effect of the interaction of sulfonylureas with the anticoagulants, chloramphenicol, clofibrate, fluconazole, histamine-2 antagonists, methyldopa, monoamine oxidase inhibitors (MAOIs), salicylates, sulfonamides, and tricyclic antidepressants. Increased risk of lactic acidosis is an effect of the interaction of metformin with glucocorticoids. Increased risk for bleeding is an effect of the interaction of oral anticoagulants with anti-infective drugs. There is a risk of acute renal failure when iodinated contrast material used for radiologic studies is administered with metformin.
