在更換敷料時，下列哪項行動展現了正確的無菌技術？
Which of the following actions demonstrates proper sterile technique during a dressing change?
- APlacing the sterile field at the edge of the table將無菌區放置在桌緣
- BHolding sterile objects above waist level✓ 正解將無菌物品保持在腰部以上
- CTurning your back to the sterile field背對無菌區
- DReaching over the sterile field with sterile gloves戴無菌手套跨越無菌區
— Explanation · 中文詳解 —
無菌技術的核心原則是保持無菌範圍（Sterile Field）在視線範圍內，且保持腰部以上。背對無菌區、跨越無菌區、或靠近桌面邊緣（被視為污染區）皆會增加污染風險。維持在腰部以上可確保操作者的視線能隨時監控該區域。
Proper sterile technique requires maintaining the sterile field within the line of vision and keeping it above waist level to prevent contamination. Items below the waist are considered unsterile, and reaching over or turning away from the field introduces potential contaminants.
✦ 台美臨床差異
基本原則完全一致，台灣臨床在執行此技術時，對周遭環境清消的規範同樣嚴格。
