一位新診斷第 2 型糖尿病的病人被處方 metformin。病人哪句話表示需要進一步衛教？
A client with newly diagnosed type 2 diabetes mellitus is prescribed metformin. Which statement by the client indicates a need for further teaching?
- A"I should take metformin with meals to reduce stomach upset."「我應該隨餐服用 metformin 以減少胃部不適。」
- B"I will stop taking metformin if my blood sugar is normal."✓ 正解「如果我的血糖正常，我就停止服用 metformin。」
- C"Metformin helps my body use insulin better."「Metformin 幫助我的身體更好地利用胰島素。」
- D"I need to report any muscle pain or dark urine to my doctor."「我需要向醫生報告任何肌肉疼痛或深色尿液。」
Metformin 是一種長效藥物，用於持續控制血糖。即使血糖恢復正常，也不應自行停藥，因為其作用是改善胰島素敏感性並減少肝臟葡萄糖生成。停藥可能導致血糖再次升高。肌肉疼痛或深色尿液可能是橫紋肌溶解的警訊，需告知醫師。
Metformin is a long-term medication used for sustained glycemic control. Even when blood sugar returns to normal, the patient should not stop taking it independently, because the drug works by improving insulin sensitivity and reducing hepatic glucose production. Discontinuation may cause blood sugar to rise again. Muscle pain or dark-colored urine may be warning signs of rhabdomyolysis and should be reported to the provider.
美國糖尿病衛教師 (CDE) 會詳細解釋口服藥物機轉和副作用；台灣則由醫師處方，護理師衛教病人用藥注意事項，但病人對藥物機轉的理解程度不一。
