護理師監測輸血病人時，病人出現蕁麻疹、搔癢與潮紅。護理師優先採取的行動為何？

輸血反應（Transfusion Reaction）發生時，護理師的優先行動（Priority Action）是立即停止輸血。蕁麻疹、搔癢與潮紅屬於輕微的過敏反應，但護理師無法預判反應是否會進展為嚴重的過敏性休克（Anaphylaxis）。因此，切斷血液輸注來源是首要任務，隨後再以生理食鹽水維持靜脈管路通暢，並通知醫療團隊進行評估。

When a transfusion reaction occurs, the nurse's priority action is to stop the transfusion immediately. Urticaria, itching, and flushing are mild allergic reactions, but the nurse cannot predict whether the reaction will progress to severe anaphylaxis. Therefore, disconnecting the source of blood infusion is the first task; the IV line is then kept patent with normal saline, and the medical team is notified for further evaluation.
