- CMaintaining a 1-inch border around the sterile field✓ 正解維持無菌區周圍一英吋的邊界
- DTurning the back to the sterile field briefly短暫背對無菌區

無菌操作的核心在於邊界與視線。無菌區邊緣一英吋（約 2.5 公分）被視為「不潔區」，物品置於此區或跨越此邊緣即視為污染。物品應保持在腰部以上視線範圍，不可背對無菌區，亦不可伸手跨越，以免掉落物造成污染。
Proper sterile technique involves maintaining a one-inch border around the sterile field, which is considered contaminated, and keeping sterile items above waist level within the line of sight. Nurses should never reach over the field, turn their back to it, or handle items below the waist to prevent contamination.
