護理師正在為病人靜脈輸注氯化鉀(KCl)。下列哪項行動是必要的?

A nurse is administering a dose of intravenous potassium chloride to a client. Which action is essential?

  • AVerify the patient's urine output before infusion✓ 正解
    在輸注前確認病人的尿液排出量
  • BAdminister as a bolus push
    作為靜脈推注給藥
  • CEnsure the concentration does not exceed 10 mEq/100 mL
    確保濃度不超過 10 mEq/100 mL
  • DInfuse at a rate of 50 mEq/hour
    以 50 mEq/hour 的速度輸注
Explanation · 中文詳解

氯化鉀具有高心臟毒性,給藥前需確保腎功能正常(尿量 >30 mL/hr),以避免高血鉀導致心跳停止。KCl 絕對禁止直接靜脈推注(Bolus),必須稀釋且透過幫浦控速。每小時輸注速率通常不超過 10-20 mEq,選項 C 雖為稀釋建議,但確保排泄途徑(腎臟)通暢是首要臨床評估。

Potassium chloride carries a high risk of cardiac toxicity, so verifying adequate urine output (typically >30 mL/hr) is essential to ensure the kidneys can excrete excess potassium. Intravenous push administration is strictly contraindicated due to the risk of fatal arrhythmias, and infusion rates must be controlled, usually not exceeding 10 mEq/hr peripherally.

✦ 台美臨床差異

美台皆將 KCl 視為高警訊藥物(High-Alert Medication),需特別標籤並透過幫浦輸注。
