A nurse teaches a client taking glipizide about preventing hypoglycemia. Which statement indicates correct understanding?

Rationale: A. Glipizide is a sulfonylurea that stimulates pancreatic insulin secretion, which can cause hypoglycemia, especially if meals are skipped or activity increases. Carrying a fast-acting carbohydrate (juice, glucose tablets, or snack) allows the client to treat mild hypoglycemia promptly, demonstrating understanding of self-management. B. Glipizide should be taken as prescribed, usually 30 minutes before meals, regardless of current blood glucose. Taking it only when hyperglycemic is unsafe and can lead to poor glycemic control or delayed hypoglycemia recognition. C. Skipping meals while taking glipizide increases the risk of hypoglycemia because insulin is still being secreted. Proper diabetes management requires regular, balanced meals to match the medication’s action. D. Alcohol can increase the risk of hypoglycemia, particularly with sulfonylureas. It may also cause flushing, nausea, or vomiting (disulfiram-like reaction). Advising alcohol use with glipizide is unsafe and demonstrates misunderstanding of medication precautions.
