護理師協助行動受限的病人從床轉移至椅子。下列哪項動作顯示護理師使用安全的身體力學？
A nurse is assisting a client with limited mobility to transfer from the bed to a chair. Which action by the nurse demonstrates safe body mechanics?
- ABending at the waist to reach the client's underarms彎腰以觸及病人腋下
- BKeeping the knees straight while lifting the client搬運病人時保持膝蓋伸直
- CTwisting the torso while pivoting the client轉動病人時扭轉軀幹
- DMaintaining a wide base of support and keeping the client close to the center of gravity✓ 正解保持寬廣的支撐基底並將病人靠近重心

人體力學（Body mechanics）的核心在於保護護理師的脊椎並確保病人轉移安全。正確的轉移技巧應包含擴大支撐面（Base of support）以增加穩定性，並將重心維持在身體的中軸線上。透過彎曲膝蓋與髖關節來發力，而非彎腰，能有效減少下背部的負擔。同時，讓病人盡量靠近護理師的身體重心，可以利用槓桿原理減少背部肌肉的拉力，防止職業傷害。
Safe body mechanics during transfers involve maintaining a wide base of support and keeping the client close to the center of gravity to maximize stability and leverage while minimizing strain on the nurse's back.
