維持無菌原則包括：保持在腰部以上視線範圍、不可跨越無菌區、僅觸碰無菌舖單邊緣一英吋（污染區）、無菌區需隨時保持在視線內（不可背對）。D 錯誤：背對無菌區會導致該區域脫離監控，即視為污染，故護理師應時刻觀察無菌區。
Maintaining a sterile field requires keeping it at or above waist level, as anything below is considered contaminated, and avoiding reaching over it to prevent particle introduction. The one-inch border of the drape is non-sterile, so only this edge should be touched, and the nurse must always face the field to monitor for contamination rather than turning their back.
