護理師教導膝關節術後病人使用持續性被動運動（CPM）機器。病人哪句話表示已理解其用途？
A nurse is teaching a client about the use of a continuous passive motion (CPM) machine following knee surgery. Which statement by the client indicates an understanding of the device?
- AI will wear this while I am sleeping at night我會在晚上睡覺時戴著這個。
- BI should adjust the speed to the highest setting for better results我應該將速度調整到最高設定以獲得更好的效果。
- CThis machine replaces the need for active physical therapy這個機器取代了主動物理治療的需求。
- DThis device helps prevent stiffness and promotes joint range of motion✓ 正解這個裝置有助於防止僵硬並促進關節活動範圍。
持續性被動運動（Continuous Passive Motion, CPM）是膝關節術後復健的重要工具，透過機械力維持關節活動度（Range of Motion, ROM），防止結締組織沾黏與關節僵硬。正確的使用觀念在於遵循醫囑的設定與時間，而非自行加量或整夜使用。臨床護理重點在於教育病人該設備是輔助復健，無法取代主動式運動（Active Physical Therapy），且需密切監測皮膚完整性。
The continuous passive motion (CPM) machine is an important tool in rehabilitation after knee surgery, using mechanical force to maintain joint range of motion (ROM) and prevent connective tissue adhesions and joint stiffness. Correct use requires following prescribed settings and duration, rather than self-adjusting the intensity or wearing the device all night. The clinical nursing focus is on educating the client that the device is an adjunct to rehabilitation, cannot replace active physical therapy, and that skin integrity must be closely monitored.
