A nurse instructs a client taking glyburide about alcohol use. What statement by the client indicates the need for further teaching?

Rationale: A. This is correct understanding. Glyburide, a sulfonylurea, can interact with alcohol to cause severe hypoglycemia or a disulfiram-like reaction. Complete avoidance of alcohol is recommended, so this statement shows proper comprehension. B. Alcohol can enhance the hypoglycemic effects of glyburide, leading to symptoms such as dizziness, lightheadedness, or fainting. The client recognizing this risk demonstrates understanding of medication-alcohol interactions. C. Alcohol can potentiate the blood-glucose-lowering effects of glyburide by inhibiting gluconeogenesis, increasing the risk of hypoglycemia. This statement shows the client understands the potential danger. D. Even small amounts of alcohol can precipitate hypoglycemia in clients taking glyburide, particularly if alcohol is consumed without food. This statement indicates a misunderstanding of the risks, so the nurse should provide further teaching to emphasize complete avoidance of alcohol while on sulfonylureas.
