護理師進行無菌換藥，下列哪種行為代表無菌技術被破壞？
A nurse is caring for a client who requires a sterile dressing change. Which action by the nurse indicates a break in sterile technique?
- ATouching the outer 1-inch border of the sterile field with bare hands以裸露雙手觸碰無菌區域的外側1英吋邊界
- BAdding a sterile item to the field by dropping it from 6 inches above從6英吋上方將無菌物品丟入無菌區域
- CReaching over the sterile field with sterile gloves✓ 正解戴著無菌手套跨越無菌區域
- DHolding sterile items above waist level將無菌物品保持在腰部以上
無菌技術（sterile technique）的嚴格執行是防止醫源性感染（nosocomial infection）的關鍵。無菌區的邊緣（1 英吋）被視為污染區，不可觸碰。作業時不可跨越無菌區，以免落塵導致污染。所有無菌物品需放置於視線範圍內，且不可低於腰部（因視線之外難以監控）。若有任何懷疑無菌狀態被破壞的情況，應立即更換物品並重新開始。
Strict adherence to sterile technique is essential to prevent nosocomial infection. The 1-inch border of the sterile field is considered contaminated and should not be touched with sterile-gloved hands. The nurse must not reach over the sterile field, as this can introduce particulate matter. All sterile items must remain within sight and above waist level, since items below the waist are difficult to monitor. If sterility is suspected to have been broken at any point, items should be replaced and the procedure restarted.
