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 reason: This is incorrect because withholding all medications may cause hyperglycemia or ketoacidosis in the patient, especially if they are taking insulin or sulfonylureas. The nurse should consult with the prescriber to adjust the dose or timing of the medications according to the patient's blood glucose level and the duration of the procedure.

Choice B reason: This is correct because contacting the prescriber to clarify orders is the best action by the nurse, as the prescriber can provide specific instructions on how to manage the patient's oral antidiabetic drugs before and after the oral endoscopy. The nurse should also monitor the patient's blood glucose level closely and report any abnormal findings to the prescriber.

Choice C reason: This is incorrect because administering half the original dose may not be appropriate for the patient, as it may cause hypoglycemia or hyperglycemia depending on the type and dose of the medication and the patient's blood glucose level. The nurse should not make any changes to the medication regimen without the prescriber's approval.

Choice D reason: This is incorrect because giving the medication with a sip of water may violate the NPO status of the patient, which is necessary to prevent aspiration or interference with the oral endoscopy. The nurse should not administer any oral medications or fluids to the patient unless the prescriber allows it.

Choice A reason: This is incorrect because the client should avoid live vaccines while taking prednisone, as it can suppress the immune system and increase the risk of infection.

Choice B reason: This is correct because prednisone can cause hypokalemia (low potassium levels) and bananas are a good source of potassium. The client should monitor their potassium levels and eat foods rich in potassium while taking prednisone.

Choice C reason: This is incorrect because the client should avoid nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin while taking prednisone, as they can increase the risk of gastrointestinal bleeding and ulceration.

Choice D reason: This is incorrect because a sore throat is not a common side effect of prednisone. However, the client should report any signs of infection, such as fever, sore throat, or cough, to the provider, as prednisone can mask the symptoms of infection.
