A nurse is assisting a client with limited mobility to transfer from the bed to a chair. Which action by the nurse demonstrates proper body mechanics?
- ATwisting the trunk to maneuver the client safely旋轉軀幹以安全移動病人
- BBending at the waist to keep the client close彎腰以保持病人靠近
- CKeeping the knees straight while lifting抬起時保持膝蓋伸直
- DMaintaining a wide base of support with feet apart✓ 正解雙腳分開以維持寬廣的支撐基底

正確的身體力學（Body mechanics）對於護理人員保護自身脊椎至關重要。移位時應採取寬基底（Wide base of support），即雙腳分開，以增加穩定性。同時應保持脊椎中線平直，運用腿部的大肌肉群出力，而非腰部。任何旋轉軀幹（Twisting）的動作都會對腰椎間盤造成極大壓力，是護理人員背部傷害的主要原因。
Proper body mechanics are critical to protecting the nurse's spine during transfers. The nurse should adopt a wide base of support, with feet apart, to increase stability. The spine should remain in midline alignment, using the large muscle groups of the legs rather than the lower back. Any twisting of the trunk places tremendous stress on the intervertebral discs and is a leading cause of back injury in nurses.
