護理師為病人輸血時，病人開始出現畏寒及背痛，護理師首要行動為何？
A nurse is caring for a client who is receiving blood transfusion. The client begins to report chills and back pain. What is the nurse's priority action?
- AAssess the client's vital signs評估病人的生命徵象
- BSlow the infusion rate減慢輸注速率
- CStop the transfusion immediately✓ 正解立即停止輸血
- DAdminister an antipyretic medication給予解熱藥物
輸血反應中，畏寒與背痛是急性溶血性輸血反應（Acute Hemolytic Transfusion Reaction）的典型症狀，這是因ABO血型不合導致的致命性免疫反應。護理師的首要行動是立即停止輸血，以切斷抗原-抗體反應的來源。隨後更換輸液管路並以生理食鹽水維持靜脈路徑，防止管路中殘留的血液繼續輸入病人體內。
During blood transfusion, chills and back pain are classic signs of an acute hemolytic transfusion reaction, a potentially fatal immune reaction caused by ABO incompatibility. The nurse's priority action is to stop the transfusion immediately to halt the antigen-antibody reaction at its source. The IV tubing is then changed and normal saline is used to maintain IV access, preventing residual blood in the tubing from continuing to enter the client.
