護理師為感染傷口的病人靜脈輸注萬古黴素（Vancomycin），病人出現臉部與頸部潮紅。優先採取的行動為何？
A nurse is administering a dose of intravenous Vancomycin to a client with a wound infection. The nurse observes the client developing flushing of the face and neck. Which action is the priority?
- AAdminister an antihistamine給予抗組織胺藥物
- BStop the infusion immediately立即停止輸注
- CIncrease the IV fluid rate增加靜脈輸液速率
- DSlow the infusion rate✓ 正解減慢輸注速率
萬古黴素（Vancomycin）輸注過快常引起「紅人症候群」（Red Man Syndrome），這是因組織胺過度釋放引起的類過敏反應，表現為臉部、頸部與上軀幹潮紅。這並非真正的過敏反應（Anaphylaxis），因此無需立即停止輸注，通常減慢輸注速度即可緩解症狀。護理師應密切觀察病人有無低血壓或呼吸窘迫。
The client is experiencing Red Man Syndrome, a histamine-mediated reaction caused by rapid vancomycin infusion, characterized by flushing of the face and neck. This is not a true anaphylactic allergy, so the priority action is to slow the infusion rate rather than stopping it completely. Antihistamines may be administered subsequently, but adjusting the infusion speed is the immediate intervention.
