A nurse is assisting a client with ambulation after surgery. Which action demonstrates correct body mechanics?
- ABending at the waist to lift the client彎腰搬起病人
- BTwisting the torso while turning the client轉動病人時扭轉軀幹
- CKeeping feet apart to create a wide base of support✓ 正解雙腳分開以建立寬廣的支撐基底
- DKeeping the client as far from the body as possible將病人盡量遠離身體

正確的身體力學旨在利用人體的自然力學結構，保護脊椎並減少肌肉骨骼損傷。在協助病人活動時，應雙腳分開以增加支撐底面積，降低重心，提升平衡感。護理師應儘量貼近病人，減少力臂以減輕腰部負擔。絕對禁止在移動病人時扭轉腰部，因為這會對脊椎盤造成極大剪力；同時應利用腿部力量而非彎腰抬舉，以預防護理師職業性背痛。
Proper body mechanics involve maintaining a wide base of support by keeping feet apart to enhance stability and balance during client ambulation. This technique lowers the center of gravity and reduces the risk of musculoskeletal injury to the nurse. Nurses should avoid twisting the torso and keep the load close to their body to minimize strain on the back.
