Which actions are essential when performing a sterile dressing change on a surgical wound? (Select all that apply.)
- AKeep the sterile field within line of vision at all times✓ 正解隨時保持無菌區域在視線範圍內
- BConsider the outer 1-inch border of a sterile field as contaminated✓ 正解將無菌區域外圍 1 吋邊緣視為已污染
- CHold sterile items above waist level✓ 正解手持無菌物品時保持在腰部以上
- DPour sterile solution into a basin held near the sterile field將無菌溶液倒入靠近無菌區的盆子中
- EPlace the sterile package on a flat, dry surface at waist level✓ 正解將無菌包放置在腰部高度的平坦乾燥表面上

維持無菌原則的核心在於確保無菌物品始終在視線範圍內，避免被污染。外圍一英吋邊緣視為污染區。無菌物品需保持在腰部以上，確保視野與安全性。D 選項錯誤：傾倒無菌溶液時，瓶口不可過度靠近無菌區或觸碰 basin，以防濺灑導致浸潤而污染。
Maintaining a sterile field requires keeping sterile items within direct line of sight and above waist level to prevent accidental contamination. The outer 1-inch border of sterile drapes is considered contaminated, so packages must be placed on stable, dry surfaces at waist height. Pouring solutions near the field risks strike-through contamination, making visual monitoring and proper positioning essential.

台灣醫院對無菌技術的稽核非常嚴謹，常配合手部衛生稽查作為醫院評鑑指標。
