護理師的哪項操作最能體現其對無菌技術的理解？
Which of the following actions by the nurse best demonstrates an understanding of sterile technique?
- ATouching the edge of the sterile drape with sterile gloves用無菌手套觸碰無單巾邊緣
- BReaching over the sterile field if necessary必要時跨越無菌區域
- CPlacing a sterile package on a wet surface將無菌包裝放置在潮濕表面上
- DHolding sterile objects above waist level✓ 正解將無菌物品保持在腰部以上高度
— Explanation · 中文詳解 —
無菌技術的核心在於維持視野清晰且避免汙染。將無菌物品保持在腰部以上能確保其在視野範圍內且不會被無意接觸。跨越無菌區、觸碰邊緣（屬於被汙染區）、將物品放置於潮濕表面（透過毛細現象滲透汙染）均違反無菌原則。
Holding sterile objects above waist level ensures they remain within the nurse's line of sight and prevents accidental contact with non-sterile surfaces below the waist. This practice maintains the integrity of the sterile field, whereas reaching over it, touching edges, or placing items on wet surfaces introduces contamination risks.
