護理師在手術室工作，哪項行為違反了無菌技術？
A nurse is working in the OR. Which activity is a violation of sterile technique?
- AA sterile person keeps their hands between waist and shoulder level無菌人員將雙手保持在腰部與肩部之間的高度
- BA non-sterile person walks between two sterile areas✓ 正解非無菌人員在兩個無菌區域之間走過
- CA sterile person faces the sterile field at all times無菌人員始終面向無菌區域
- DA sterile person touches only sterile items無菌人員僅觸碰無菌物品
手術室無菌技術（Sterile Technique）的核心在於維持無菌區的完整性。無菌區是指經過滅菌處理的區域，任何非無菌物體進入該區域都會導致污染。非無菌人員（Non-sterile person）穿越兩個無菌區之間，會切斷無菌路線（sterile corridor），造成潛在的交叉污染風險，這是明確的技術違規。臨床上，護理師必須嚴格監控無菌區邊界，確保人員移動路徑不干擾無菌操作。
The core of sterile technique in the operating room is maintaining the integrity of the sterile field. The sterile field is the area that has undergone sterilization; entry by any non-sterile object causes contamination. A non-sterile person walking between two sterile areas breaks the sterile corridor and creates a clear risk of cross-contamination, which is an unambiguous breach of technique. Clinically, the nurse must strictly monitor sterile field boundaries to ensure that personnel movement paths do not interfere with sterile operations.
台美在手術室的無菌原則高度一致。美國手術室（OR）對無菌區的維護非常嚴謹，通常由洗手護理師（Scrub Nurse/Tech）負責監控，巡迴護理師（Circulating Nurse）則負責維持非無菌區的安全與環境。
