護理師為蜂窩性組織炎病人靜脈注射萬古黴素時，發現病人臉部及頸部潮紅。下列何者為首要處置？
A nurse is administering a dose of intravenous Vancomycin to a client with cellulitis. The nurse notes the client developing flushing on the face and neck. Which action should the nurse take first?
- ANotify the healthcare provider通知醫療提供者
- BAdminister an antihistamine給予抗組織胺
- CSlow the infusion rate✓ 正解減緩輸注速度
- DStop the infusion immediately立即停止輸注
此為典型的紅人症候群（Red Man Syndrome），因萬古黴素輸注速度過快導致組織胺釋放。處置原則是減慢輸注速度。若出現低血壓或過敏性休克徵兆（如呼吸困難），才需停止輸注。相較於停藥，減速通常能緩解症狀並確保治療完成。
This is a typical presentation of Red Man Syndrome caused by overly rapid vancomycin infusion, which leads to histamine release. The management principle is to slow the infusion rate. The infusion is only stopped if the client develops signs of hypotension or anaphylaxis (such as respiratory distress). Compared with stopping the medication, slowing the rate generally relieves symptoms and allows treatment to be completed.
台美臨床對紅人症候群的處置一致，強調監測輸注速率與症狀分級。
