A patient who has type 2 diabetes is scheduled for an oral endoscopy and has been NPO (nothing by mouth) since midnight. What is the best action by the nurse regarding the administration of her oral antidiabetic drugs?

Choice A rationale: Administering half the dose of an oral antidiabetic medication without food can still cause hypoglycemia. The patient is NPO, meaning their body is not receiving any glucose from food intake. Oral antidiabetic drugs lower blood glucose. Even a reduced dose could precipitate a hypoglycemic episode, which is particularly dangerous in a hospitalized patient undergoing a procedure. Choice B rationale: Withholding all medications as ordered is not always the correct action without a specific order. While withholding the medication is likely the correct course of action for an NPO patient, a nurse should always follow a prescriber's explicit orders. A nurse should not withhold medications independently, especially when the patient is on a scheduled medication regimen, as this could lead to unintended consequences. Choice C rationale: The nurse should contact the prescriber for orders to clarify the patient's medication regimen. Patients who are NPO should not take oral medications that can cause hypoglycemia without a food source. Therefore, a new order is needed to either withhold the medication or adjust the dose based on the patient's fasting status and blood glucose levels, ensuring patient safety. Choice D rationale: Giving the medication with a sip of water is dangerous because it provides no nutritional support to counteract the medication's glucose-lowering effects. Since the patient is NPO, they are not consuming food, and the medication could cause a severe hypoglycemic event. Additionally, taking anything by mouth may violate the NPO status required for the endoscopy, compromising the procedure.
