When teaching a patient who is starting metformin, which instruction by the nurse is correct?
- A. Take metformin if your blood glucose level is above 100 mg/dL.
- B. Take this 60 minutes after breakfast.
- C. Take the medication on an empty stomach 1 hour before meals.

A patient in the emergency department was showing signs of hypoglycemia and had a fingerstick glucose level of 38 mg/dL. The patient has just become unconscious. The nurse will anticipate which action to be next?
- A. Having the patient eat glucose tablets
- B. Having the patient consume fruit juice, a nondiet soft drink, or crackers
- C. Administering intravenous glucose (50% dextrose)
- D. Calling the lab to order a fasting blood glucose level
Correct Answer: C
Rationale: Unconscious patients with hypoglycemia require IV glucose (e.g., 50% dextrose) to rapidly restore blood sugar, as oral intake is not possible. Lab tests are not immediate priorities.

- D. Evening blood glucose level below 80 mg/dL
