Question 2 of 5
A patient has been diagnosed with metabolic syndrome and is started on the biguanide metformin. The nurse knows that the purpose of the metformin, in this situation, is which of these?

Question 3 of 5
When administering morning medications for a newly admitted patient, the nurse notes that the patient has an allergy to sulfa drugs. There is an order for the sulfonylurea glipizide (Glucotrol). Which action by the nurse is correct?
Correct Answer: B
Rationale: Sulfa drug allergies may cross-react with sulfonylureas like glipizide, so the nurse must verify the order with the prescriber to ensure safety.
