護理師準備為病人靜脈輸注氯化鉀，哪項護理行動對於病患安全最為關鍵？
A nurse is preparing to administer potassium chloride IV infusion to a client. Which nursing action is most critical for patient safety?
- AAdminister the potassium as a rapid IV bolus以快速靜脈推注方式給予鉀離子
- BCheck the client's current potassium level檢查病人目前的鉀離子濃度
- CVerify the flow rate with an infusion pump✓ 正解與輸注幫浦確認輸注流速
- DEnsure the IV site is patent and without redness確保靜脈通路暢通且無紅腫
— Explanation · 中文詳解 —
氯化鉀具有極強的心臟毒性。靜脈輸注時，必須透過輸液幫浦精準控制流速，嚴禁推注。若速度過快可能導致心律不整甚至心跳停止。雖然監測鉀離子值與血管通暢性也很重要，但輸液速度控制是預防致命性給藥錯誤的第一道防線。
Potassium chloride is highly cardiotoxic. During intravenous infusion, the flow rate must be precisely controlled by an infusion pump, and IV push is strictly forbidden. Excessive infusion rates may cause arrhythmias or even cardiac arrest. Although monitoring potassium levels and ensuring vascular patency are also important, controlling the infusion rate is the first line of defense against fatal medication errors.
