病人正接受氯化鉀 20 mEq 靜脈輸注，護理師發現輸注部位腫脹、觸感冰冷且蒼白。哪項措施為優先？
A client is receiving an intravenous infusion of potassium chloride 20 mEq in 100 mL of 0.9% Normal Saline. The nurse notes the infusion site is swollen, cool to the touch, and pale. Which action is the priority?
- ANotify the physician通知醫師
- BApply a warm compress to the site在患處應用熱敷
- CStop the infusion immediately✓ 正解立即停止輸注
- DCheck for blood return in the IV line檢查靜脈管路是否有血液回流
氯化鉀（KCl）屬於高警訊藥物（High-alert medication），具強烈的血管刺激性。若發生靜脈滲漏（Infiltration），藥物進入皮下組織會引起嚴重的組織壞死與血管收縮。護理師發現滲漏徵象（腫脹、冰冷、蒼白）時，第一優先動作是「停止輸注」，以阻斷藥物持續進入組織，隨後再進行處理。
Potassium chloride (KCl) is a high-alert medication that is highly irritating to blood vessels. If infiltration occurs, the medication enters the subcutaneous tissue and causes severe tissue necrosis and vasoconstriction. When the nurse identifies signs of infiltration (swelling, coolness, pallor), the first priority is to stop the infusion in order to prevent additional drug from continuing to enter the tissues; subsequent management can then follow.
