A client with type 2 diabetes on glyburide asks whether they should take an extra tablet before exercise. What is the best nursing response?

• A. Decrease how much you exercise
• B. An extra pill will help your body use glucose when exercising
• C. The amount of medication you need to take is not related to exercising
• D. Do not take an extra pill because you may become hypoglycemic when exercising

Answer: (D)

The main concept is that sulfonylurea medications like glyburide lower blood glucose by increasing insulin release, and exercise increases glucose usage by muscles while also increasing insulin sensitivity. Giving an extra dose before exercising can push blood glucose too low, leading to hypoglycemia during activity. That’s why the safest nursing response is to avoid taking an extra pill before exercise. Instead, suggest monitoring blood glucose around exercise and having a quick carbohydrate source if needed, and consult with a clinician about dose adjustments if exercise consistently affects glucose.
