護理師正在照護一位第二型糖尿病病人，該病人近期開始服用 Metformin。病人哪項陳述需要後續追蹤？
A nurse is caring for a client with type 2 diabetes mellitus and has been recently started on metformin. Which statement by the client requires follow-up?
- A"I am checking my blood sugar regularly."「我定期檢查我的血糖。」
- B"I feel dizzy and have muscle cramps."✓ 正解「我感到頭暈且有肌肉痙攣。」
- C"I have noticed some nausea after taking the medication."「我注意到服藥後有些噁心。」
- D"I am trying to eat healthier meals."「我正嘗試吃得更健康。」
Metformin 最嚴重的潛在併發症是乳酸酸中毒（lactic acidosis），儘管罕見，但初期症狀可能包括噁心、嘔吐、腹瀉、肌肉疼痛、呼吸困難、極度疲勞、頭暈等。頭暈和肌肉痙攣是需要進一步評估的警訊。噁心是常見的副作用，通常會隨時間改善。血糖監測和飲食調整是正確的。
The most serious potential complication of metformin is lactic acidosis—rare but life-threatening. Early symptoms include nausea, vomiting, diarrhea, muscle pain or cramps, dyspnea, marked fatigue, and dizziness. Dizziness with muscle cramps requires follow-up to rule out lactic acidosis. Mild nausea is a common, transient side effect; blood glucose monitoring and healthy eating are appropriate.
美國的藥師會主動提供 Metformin 的副作用衛教，並提醒病人注意乳酸酸中毒的早期症狀；台灣的照護模式也包含此部分，但病人對副作用的警覺性可能因個人健康識能而異。
