護理師正在為病人進行靜脈輸注氯化鉀。下列哪些情況發生時，護理師應立即停止輸注？（選所有適合的）
A nurse is caring for a client who is receiving intravenous potassium chloride. Which of the following findings indicate the nurse should stop the infusion? (Select all that apply.)
- AThe infusion site shows redness and edema✓ 正解輸注部位呈現紅腫
- BThe client reports a burning sensation at the IV site✓ 正解病人報告靜脈注射部位有灼熱感
- CThe client's urine output is 40 mL/hr病人尿液排出量為每小時40毫升
- DThe client experiences cardiac arrhythmias on the monitor✓ 正解監測器顯示病人出現心律不整
- EThe client complains of moderate thirst病人抱怨中度口渴
氯化鉀具有強烈的組織刺激性。選項 A 與 B 為滲漏（Infiltration）跡象，極易導致組織壞死；選項 D 顯示高鉀血症已造成心律不整，嚴重威脅生命。C 選項的尿量正常，為給予鉀離子的安全指標；E 選項口渴並非鉀離子輸注的特殊不良反應。
Redness, edema, and burning sensations at the IV site indicate infiltration or phlebitis, which pose a high risk for tissue necrosis when infusing potassium chloride. Additionally, the development of cardiac arrhythmias suggests hyperkalemia, a potentially fatal complication requiring immediate cessation of the infusion. Adequate urine output confirms safe renal excretion, making it a positive indicator rather than a reason to stop.
美國常由護理師主導靜脈注射給藥判斷，台灣對於含鉀靜脈液體給予，護理師需確認醫囑濃度與輸注速率之嚴格限制。
