A nurse is providing teaching to a client who has a new diagnosis of type 2 diabetes mellitus. The nurse should recognize that the client understands the teaching when he identifies which of the following as manifestations of hypoglycemia? (Select all that apply)

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: Hyperkalemia is not the correct answer. Hyperkalemia is a high level of potassium in the blood. Corticosteroids do not cause hyperkalemia, but rather hypokalemia. Hyperkalemia may be caused by other factors such as renal failure, acidosis, or potassium-sparing diuretics.

Choice B reason: Hypokalemia is the correct answer. Hypokalemia is a low level of potassium in the blood. Corticosteroids can cause hypokalemia by increasing the excretion of potassium and sodium in the urine. Hypokalemia can cause muscle weakness, cramps, arrhythmias, and digoxin toxicity.

Choice C reason: Hypermagnesemia is not the correct answer. Hypermagnesemia is a high level of magnesium in the blood. Corticosteroids do not affect magnesium levels. Hypermagnesemia may be caused by other factors such as renal failure, excessive antacid use, or magnesium-containing laxatives.

Choice D reason: Hypomagnesemia is not the correct answer. Hypomagnesemia is a low level of magnesium in the blood. Corticosteroids do not affect magnesium levels. Hypomagnesemia may be caused by other factors such as malnutrition, alcoholism, or diuretic use.
