Which of the following actions by a nurse would violate surgical asepsis? (Select all that apply.)
- AReaching over the sterile field to hand an instrument✓ 正解跨越無菌區遞送器械
- BAllowing the sterile drape to touch the edge of the table✓ 正解允許無菌單接觸桌緣
- CKeeping the sterile field within the line of vision將無菌區保持在視線範圍內
- DConsidering the outer 1-inch border of the sterile drape as contaminated將無菌單外側 1 吋邊緣視為受污染

外科無菌原則（Surgical asepsis）要求所有進入無菌區的物品必須保持絕對無菌。越過無菌區（Reaching over）會導致微生物因重力墜落造成污染；無菌布邊緣若垂下桌面，因其超出無菌視線範圍且易觸碰非無菌物，被視為已污染區域。護理師應隨時監控無菌區，確保無菌物品始終在視線範圍內，且避免任何潛在的污染動作。
Reaching over a sterile field violates aseptic technique because air currents and falling debris can introduce microorganisms. Additionally, allowing a sterile drape to touch the edge of the table contaminates the field, as the border is considered unsterile. Nurses must keep sterile items within their line of sight and avoid any actions that bridge the sterile and non-sterile zones.
