塗抹無菌敷料時，哪項操作正確？
Which action is correct when applying a sterile dressing?
- APlace the dressing on the edge of the sterile field將敷料放置在無菌區的邊緣。
- BUse clean gloves throughout the procedure整個過程使用清潔手套。
- CKeep the dressing package within sterile boundaries✓ 正解將敷料包裝保持在無菌範圍內。
- DTouch the inner surface of the dressing觸摸敷料的內表面。
無菌技術（Sterile technique）的核心在於維持無菌區域（Sterile field）的完整性。無菌敷料的包裝內面即為無菌面，必須確保其位於無菌範圍內，避免與非無菌表面接觸。一旦無菌物品接觸到非無菌表面、潮濕區域或過期，即視為污染。護理師在操作時需展現對無菌邊界的嚴格掌控，避免觸碰敷料內面或將其放置於邊緣（邊緣常被視為無菌場的污染區）。
The core of sterile technique is to maintain the integrity of the sterile field. The inner surface of a sterile dressing package is itself sterile and must remain within the sterile boundaries, never touching a non-sterile surface. Once a sterile item touches a non-sterile surface, a wet area, or becomes expired, it is considered contaminated. The nurse must demonstrate strict control of sterile boundaries during the procedure, avoiding contact with the inner surface of the dressing or placing it at the edge of the sterile field (edges are considered contaminated zones).
