無菌操作要求所有無菌物品皆須位於腰部以上，進入視線範圍內以確保未被污染。腰部以下被視為污染區。選項 D、A 會導致無菌區暴露於不可控的微粒或觸碰風險中；選項 C 雖然正確，但 A 是最核心的行為原則。
Holding sterile objects above waist level demonstrates an understanding of sterile technique, as the area below the waist is considered contaminated. Maintaining sterile items within the line of sight and above the waist ensures they remain uncontaminated during procedures.
