病人正在靜脈滴注萬古黴素，護理師觀察到病人臉部與頸部潮紅。下列哪項為優先處理措施？
A client is prescribed intravenous vancomycin. The nurse notes the client has developed flushing of the face and neck. What is the priority nursing action?
- AAdminister an antihistamine給予抗組織胺
- BAssess the client's blood pressure評估病人的血壓
- CSlow the rate of the infusion✓ 正解減緩輸注速率
- DStop the infusion immediately立即停止輸注
此為典型的紅人症候群（Red Man Syndrome），是因為萬古黴素輸注速度過快導致組織胺釋放。若無低血壓或其他過敏反應，只需減緩滴速即可緩解，不必強行停止給藥導致療程中斷。若貿然停藥或直接給抗組織胺，可能過度干預或忽視藥物動力學的調整需求。
This is a classic presentation of Red Man syndrome, which results from histamine release caused by overly rapid vancomycin infusion. In the absence of hypotension or other allergic features, slowing the infusion rate is sufficient to relieve symptoms, and there is no need to stop the medication and interrupt therapy. Stopping the infusion abruptly or immediately administering antihistamines may represent over-treatment and overlook the importance of adjusting the medication's pharmacokinetics.
台美臨床對於 Vancomycin 紅人症候群的處置策略一致，皆強調速度調整而非停藥。
