護理師執行無菌換藥技術，下列哪些行為會破壞無菌原則？（選所有適合的）
A nurse is using sterile technique to perform a dressing change. Which actions compromise sterility? (Select all that apply.)
- AReaching over the sterile field✓ 正解跨越無菌區域
- BTurning away from the sterile field✓ 正解背對無菌區域
- CKeeping the hands above the waist level將雙手保持在腰部以上
- DAllowing the edge of the sterile drape to touch the table✓ 正解允許無菌單的邊緣接觸桌面
- EDropping a sterile item from 6 inches above the field將無菌物品從距離無菌區 6 英吋上方掉落
— Explanation · 中文詳解 —
無菌區的邊緣一吋視為已污染，碰到桌面即污染（D）。轉身背對無菌區（B）可能導致視線離開，造成意外污染。伸手跨過無菌區（A）會使衣物上的微粒掉落。保持雙手在腰以上（C）及從高處放下無菌品（E）皆是正確的無菌技術。
Reaching over the sterile field allows particles from clothing to contaminate the area, while turning away removes visual supervision, increasing the risk of accidental contamination. Additionally, the outer one-inch edge of a sterile drape is considered unsterile, so allowing it to touch the table compromises sterility.
