護理師評估新進人員對於無菌技術的認知，哪句話代表正確理解？
A nurse is evaluating a new staff member's knowledge of infection control. Which statement by the staff member indicates a correct understanding of sterile technique?
- AReaching over a sterile field is acceptable if moving quickly如果動作迅速，跨越無菌區是可以接受的
- BSterile gloves may touch the outer wrapper of a sterile kit無菌手套可以觸碰無菌套組的外層包裝
- CThe inner edges of a sterile package are considered contaminated無菌包裝的內緣被視為已受污染
- DA sterile field should be kept above the level of the waist✓ 正解無菌區應保持在腰部以上水平
無菌技術的核心準則：腰部以上視為無菌區，因為低於腰部視線外容易遭汙染（D）。選項 C 錯誤，邊緣 2.5 公分（1 英吋）外才視為汙染。選項 B 錯誤，戴上無菌手套後不可接觸無菌包裝外緣。選項 A 錯誤，跨越無菌區即構成污染。
Core principles of sterile technique: above the waist is regarded as sterile, because anything below the waist is out of sight and easily contaminated (D). Option C is incorrect because only the area beyond 2.5 cm (1 inch) from the edge is considered contaminated. Option B is incorrect because, after donning sterile gloves, one must not touch the outer edge of the sterile packaging. Option A is incorrect because reaching across the sterile field constitutes contamination.
美式教學極度強調無菌技術的準則（Aseptic Technique），台灣臨床在手術室非常嚴謹，但在病房處置時偶有妥協，需持續落實標準規範。
