護理師準備靜脈輸注氯化鉀，下列哪項措施是確保安全的核心優先事項？
A nurse is preparing to administer potassium chloride intravenously to a client. Which action is the priority to ensure safety?
- AUse an infusion pump to regulate the flow rate✓ 正解使用輸注幫浦調節流速
- BEnsure the concentration is no greater than 10 mEq/100 mL確保濃度不超過 10 mEq/100 mL
- CVerify the patient's serum potassium level核對病人的血清鉀濃度
- DCheck the IV site for patency檢查靜脈通路是否通暢
— Explanation · 中文詳解 —
氯化鉀屬於高警訊藥物，靜脈給藥最重要的安全護理是透過輸液泵浦精確控制速度，防止因為滴速過快導致心律不整甚至心搏停止。雖然確認血鉀值與濃度同樣重要，但在執行給藥動作時，物理性的流速控制是防止致命性過量給藥的最後一道防線。
Potassium chloride is a high-alert medication, and the most important safety measure during IV administration is precise rate control via an infusion pump to prevent fatal arrhythmias or cardiac arrest from too-rapid infusion. While verifying serum potassium and concentration are also important, physical rate control is the last line of defense against lethal overdose during administration.
✦ 台美臨床差異
美台皆將 KCl 列為高警訊藥物，台灣醫院對 KCl 靜脈注射的規範非常嚴謹，多要求必須由兩位護理師雙重核對。
