護理師協助行動受限的病人進行床上擦澡。下列哪項護理行為表現出正確的身體力學運用？
A nurse is assisting a client with mobility limitations to perform a bed bath. Which action by the nurse demonstrates proper body mechanics?
- ARaising the bed to waist level before beginning the bath✓ 正解開始擦澡前將床升至腰部高度
- BKeeping the feet together to maintain a narrow base of support雙腳併攏以保持狹窄的支撐基底
- CTwisting the torso while reaching for supplies伸手取物時扭轉軀幹
- DBending at the waist to reach across the bed彎腰跨越床鋪取物
— Explanation · 中文詳解 —
正確身體力學原則包括調整作業高度以避免背部過度彎曲。將病床升至護理師腰部高度可減少脊椎承受壓力。彎腰（D）、雙腳併攏（B）與軀幹扭轉（C）皆會增加腰部受傷風險，應保持雙腳分開以擴大支撐面並運用大腿肌力。
Proper body mechanics include adjusting the work surface to avoid excessive bending of the back. Raising the bed to the nurse's waist level reduces spinal strain. Bending at the waist (D), keeping the feet together (B), and twisting the torso (C) all increase the risk of back injury; the feet should remain apart to widen the base of support and the leg muscles used for power.
✦ 台美臨床差異
美國醫院極度強調預防背傷以降低職災補償費用；台灣早期護理教育也強調，但在人力不足時常忽略。
