一位加護病房護理師與同事合作，手動為一位體重 120 公斤且已插管的 ARDS 病患進行俯臥翻身。這名護理師將雙腳緊緊併攏站立，彎腰，並主動扭轉脊椎來改變病患沉重臀部的位置。突然間，她感覺到一陣刺痛放射至她的左腿。這名護理師違反了哪項關鍵的人體工學原則而導致這種機制性的傷害？
An ICU nurse collaborates with a coworker to manually pronate a 120-kg (264-lb) intubated ARDS patient. The nurse stands with her feet tightly together, bends at the waist, and actively twists her spine to reposition the patient's heavy hips. Suddenly, she feels a sharp, radiating pain down her left leg. Which critical ergonomic principle did the nurse violate leading to this mechanism of injury?
- AShe utilized her lower back muscles and twisted her lumbar spine while bearing a maximal loaded weight rather than pivoting her feet.✓ 正解她在承受最大負重時使用了下背部肌肉並扭轉腰椎，而不是轉動雙腳。
- BShe failed to lock her elbows straight while maneuvering the patient's immense body weight.她在搬動病患的巨大體重時未能鎖直手肘。
- CShe positioned herself on the side of the bed opposite to the direction of the intended turn rather than pulling toward her.她站在與預期翻身方向相反的床邊，而不是向自己拉動。
- DShe attempted a manual lift without wearing a protective lumbar support belt during the entire procedure.她在整個過程中未穿戴保護性護腰帶就嘗試徒手搬運。
本題測驗提昇人體工學與護理職業傷害預防（Ergonomics in Safe Patient Handling）。護理師犯了三個經典導致腰椎椎間盤突出的禁忌：底盤狹窄（沒有雙腳張開提供支撐）、彎曲且用背部肌肉而非大腿強壯肌肉發力，以及最危險的動作——在承受巨大負重的狀態下「扭轉（Twisting）脊椎」。正確的安全處置應是：雙腳分開與肩同寬（提高穩定性），彎曲膝蓋使用股四頭肌發力，並且用「移動腳步（Pivoting the feet）」來改變方向，絕對不可在抬舉重物時旋轉軀幹。選項D穿戴護腰帶雖常見，但在實證醫學上它不具有絕對保護效果，若姿勢錯誤仍會受傷（甚至護腰帶會使核心肌群退化）。
The nurse likely suffered a back injury by twisting her lumbar spine while bearing a maximal load with her feet close together, which creates dangerous shear forces. Proper body mechanics require standing with feet shoulder-width apart, bending at the knees, and pivoting the feet rather than twisting the torso when moving heavy patients.
這在台美護理教育中幾乎完全雷同。『No Twisting(禁止扭動脊椎)』、『Use leg muscles, not back(用大腿發力非背部)』是全球公認的勞動安全圭臬。
