護理師照護一位正接受靜脈輸注氯化鉀的病人。發現輸液部位腫脹、觸感冰冷且蒼白。護理師應採取的最優先行動為何？
A nurse is caring for a client with a continuous intravenous infusion of potassium chloride. The nurse notices the site is swollen, cool to the touch, and pale. Which action is the priority?
- AStop the infusion and remove the IV catheter✓ 正解停止輸注並拔除靜脈導管
- BCheck for blood return before proceeding繼續操作前先檢查是否有血液回流
- CApply a warm compress to the area在該部位施加溫敷
- DSlow the infusion rate to prevent further damage減緩輸注速率以防止進一步損傷
靜脈輸注氯化鉀（KCl）若發生滲漏（Infiltration/Extravasation），由於 KCl 屬於高刺激性藥物，會導致局部組織壞死（Tissue Necrosis）或化學性灼傷。首要行動是立即停止輸注以防更多藥物進入皮下組織，並拔除導管以減少進一步損傷。後續處置則依醫院政策進行冷敷或溫敷，並觀察組織受損狀況。
If infiltration or extravasation of intravenous potassium chloride (KCl) occurs, the highly irritating nature of KCl can cause local tissue necrosis or chemical burns. The priority action is to immediately stop the infusion to prevent additional medication from entering the subcutaneous tissue, and to remove the catheter to limit further injury. Subsequent management, such as warm or cold compresses, is performed according to facility policy while monitoring the affected tissue.
