A nurse is providing teaching regarding acarbose. The nurse would tell the client that which expected side or adverse effect(s) may occur with this medication? Select all that apply.

A. Abdominal distention: Acarbose delays carbohydrate absorption in the intestine, leading to increased fermentation by gut bacteria. This process commonly causes gas, bloating, and abdominal distention as expected side effects. B. Tachycardia: Acarbose does not directly affect cardiac conduction or heart rate. Tachycardia is not associated with this medication and would more likely suggest another underlying issue. C. Diarrhea: Gastrointestinal side effects such as diarrhea are frequent with acarbose use. They result from unabsorbed carbohydrates being metabolized in the colon, producing osmotic effects that increase stool looseness. D. Dizziness: Dizziness is not a typical side effect of acarbose. If experienced, it may be related to hypoglycemia when combined with other diabetes medications, but acarbose alone does not usually cause this. E. Decreased hearing: Hearing loss is not linked to acarbose therapy. This adverse effect is not reported in association with alpha-glucosidase inhibitors. F. Hyperglycemia: Acarbose is used to lower postprandial blood glucose levels, not increase them. Hyperglycemia is not an adverse effect of this drug and would indicate ineffective therapy or nonadherence.
