護理師督導新進護理師執行無菌技術，哪項行為需要立即介入糾正？
A nurse is supervising a newly licensed nurse who is preparing a sterile field. Which action requires the nurse to intervene?
- AKeeping the sterile field within the line of vision將無菌區域保持在視線範圍內
- BOpening the outermost flap of a sterile kit away from the body將無菌套裝最外層摺角朝遠離身體方向打開
- CPlacing a sterile package on a dry, waist-high surface將無菌包裝放置於乾燥、腰部高度的平面上
- DReaching over the sterile field with a sterile glove✓ 正解戴無菌手套跨越無菌區域

無菌技術（Sterile technique）的目的在於完全排除微生物污染。無菌區（Sterile field）的邊緣被視為污染區（通常為外緣 2.5 公分）。任何跨越（Reaching over）無菌區的動作，即使配戴無菌手套，也會因空氣中微粒的飄落而污染無菌區。因此，護理師應從側面接近無菌區進行操作。
Reaching over a sterile field compromises its sterility because airborne particles can settle on the area, even if the nurse is wearing sterile gloves. To maintain aseptic technique, the nurse should approach the field from the side rather than crossing over it.
