一位病人正接受靜脈注射萬古黴素（Vancomycin），出現何種情況時護理師應立即停止給藥？

Red Man Syndrome 是萬古黴素輸注過快造成的類過敏反應，常見特徵為臉部、頸部及上半身潮紅，甚至合併低血壓。處理原則為暫停輸注，待症狀緩解後依醫師評估減慢速度重新給予。選項 A 為局部輕微刺激非急停標準，C 與 D 為正常生理數值。

Red Man Syndrome is an anaphylactoid (non-IgE-mediated) reaction caused by rapid vancomycin infusion. It manifests as flushing of the face, neck, and upper torso, sometimes with hypotension. Management is to stop the infusion and, once symptoms resolve, restart at a slower rate per provider order. Option A is mild local irritation rather than a stop-the-infusion criterion, and C and D are normal vital signs.

台美兩地對 Vancomycin 給藥速度均有嚴格規範，台灣護理師通常會諮詢藥師確認給藥時間。
