A charge nurse is observing a new nurse perform a sterile dressing change. Which action by the new nurse indicates a breach of sterile technique?

無菌技術（Sterile technique）的核心在於維持無菌區域不受任何微生物污染。跨越（reaching across）無菌野會導致護理師的衣物或身體部位暴露於無菌範圍上方，增加脫屑或飛沫掉落污染的風險。在NCLEX考題中，無菌區域的邊緣、低於腰部區域，以及跨越無菌區的動作，均被視為嚴重的技術疏失。一旦發生上述狀況，該無菌區域即被視為受污染，必須終止操作並重新準備，以確保病人安全。
Reaching across a sterile field breaches sterile technique because unsterile clothing or body parts may contaminate the area through shedding or droplets. Sterile items should be transferred without crossing the sterile zone, and the field must be maintained at waist level or above. Any breach requires discarding the contaminated items and restarting the procedure to ensure client safety.
