護理師照護一位新診斷為第二型糖尿病的病人，下列何項出院指導對其自我管理最重要？
A nurse is caring for a client with a new diagnosis of type 2 diabetes mellitus. Which discharge instructions are most important for self-management?
- ATake all prescribed medications at bedtime於就寢時服用所有處方藥物
- BIncrease physical activity to 60 minutes daily增加活動量至每日60分鐘
- CMonitor blood glucose levels as prescribed✓ 正解依指示監測血糖值
- DAdhere to a strict ketogenic diet嚴格遵循生酮飲食
血糖監測是第二型糖尿病自我管理的核心。透過規律的血糖監測，病人能具體了解自身的飲食、運動與藥物對血糖的影響。這種自我回饋機制能協助病人及時調整生活方式，維持血糖於目標範圍內，從而減少長期併發症（如視網膜病變、腎病變）。其他選項（如酮酸飲食、運動量、服藥時間）可能因人而異，血糖監測則是所有糖尿病管理的基礎。
Blood glucose monitoring is the cornerstone of self-management for type 2 diabetes. Regular monitoring allows the client to see in concrete terms how diet, exercise, and medication affect glucose levels. This self-feedback loop helps the client adjust lifestyle factors in a timely way and keep glucose within the target range, reducing long-term complications such as retinopathy and nephropathy. The other options (ketogenic diet, exercise volume, medication timing) vary among individuals, whereas blood glucose monitoring underpins all diabetes management.
