無菌技術（Sterile technique）要求任何位於無菌區域（Sterile field）內的物體必須隨時處於護理師的視線範圍內。背對無菌區會導致該區域脫離監控，無法確保是否有未察覺的污染發生（例如衣服觸碰、他人誤觸）。在 NCLEX 考試中，任何「無法監控」的行為皆被視為污染，必須重新執行程序。
Sterile technique requires that anything within the sterile field remain in the nurse's line of vision at all times. Turning your back removes the field from view and prevents detection of unnoticed contamination (e.g., contact with clothing or others). On the NCLEX, any 'unmonitored' action is considered contaminated, and the procedure must be redone.
