Which action by the nurse maintains the sterile field during a procedure?

- BPutting on a clean, non-sterile gown穿上乾淨的非無菌隔離衣
- CTurning your back to the sterile field背對無菌區
- DKeeping sterile items within your field of vision✓ 正解保持無菌物品在視線範圍內

無菌技術（Sterile technique）的核心在於維持無菌區（Sterile field）的完整性，任何超出視線範圍或遭到非無菌物體接觸的區域均視為污染。護理師應時刻監控無菌區，確保所有無菌物品均在視線範圍內，且嚴禁背對無菌區，因為背後的區域無法確保未受污染。臨床操作中，安全性與無菌完整性優先於操作效率，任何懷疑受污染的物品都應立即丟棄並更換。
The sterile field must remain in the nurse's direct line of sight at all times; anything out of view is considered contaminated. Turning one's back to the field, allowing the drape edge to touch a non-sterile surface, or wearing a non-sterile gown all violate sterile technique. Strict surveillance and immediate replacement of any suspected contamination preserves field integrity.
