護理師觀察實習護生執行無菌換藥，下列哪項行為需要護理師立即介入糾正？
A nurse is observing a nursing student performing a sterile dressing change. Which action by the student requires the nurse to intervene immediately?
- AUsing sterile forceps to transfer items to the field使用無菌鑷子將物品移至無菌區
- BTurning their back to the sterile field✓ 正解背對無菌區
- CPlacing the sterile field above waist level將無菌區置於腰部以上
- DOpening the sterile package away from the body first先開啟遠離身體一側的無菌包裝

無菌技術要求視線不得離開無菌區域。背對無菌區會導致該區域脫離視線，無法確保其無菌狀態，此為嚴重的無菌技術錯誤，應立即制止。其他選項均符合無菌操作規範：腰部以上為無菌區、包裝向外開啟可避免污染、鑷子轉移物件屬正確方式。
Turning one's back to the sterile field compromises sterility because the area is no longer within the nurse's direct line of sight, making contamination undetectable. This action requires immediate intervention to prevent infection. Other options, such as keeping the field above waist level and opening packages away from the body, are correct techniques for maintaining a sterile environment.
