Which action by the nurse demonstrates proper use of sterile technique during a dressing change?
- ATurning the back to the sterile field to reach for supplies背對無菌區以取用物品
- BHolding sterile objects above waist level✓ 正解將無菌物品保持在腰部以上

- DOpening the sterile drape by pulling the top flap toward the body將無菌布頂端摺頁朝向身體方向掀開

無菌技術的核心在於維持視野內的潔淨度。物品若低於腰部（或無菌作業平面），則視為污染。轉身背對無菌區會導致失去監控，違反無菌原則；無菌手套只能觸碰無菌物品，而非邊緣；打開無菌布應由遠而近以避免跨越污染。
Holding sterile objects above waist level maintains visibility and prevents contamination, as items below the waist are considered non-sterile. Turning the back to the field, touching the contaminated outer border, or opening drapes incorrectly all violate sterile technique principles by introducing potential contaminants.
