護理師準備靜脈輸注氯化鉀,針對此類高警訊藥物,哪項安全措施是強制性的?

A nurse is preparing to administer potassium chloride intravenously. Which safety action is mandatory for this high-alert medication?

  • AAdminister the full dose in 30 minutes
    在 30 分鐘內給予全劑量
  • BAdminister via IV push for rapid correction
    透過靜脈推注給予以快速糾正
  • CAssess blood pressure every 5 minutes during infusion
    輸注期間每 5 分鐘評估血壓
  • DEnsure the medication is diluted and administered via an infusion pump✓ 正解
    確保藥物稀釋並透過輸液幫浦給予
Explanation · 中文詳解

氯化鉀(KCl)是高警訊藥物(High-alert medication),其靜脈輸注濃度與速度需嚴格管控。若輸注過快或濃度過高,會導致心律不整甚至心跳停止(Cardiac Arrest)。因此,臨床上必須稀釋並使用輸液幫浦(Infusion pump)來精確控制流速,這是確保病人安全的核心護理措施。

Potassium chloride is a high-alert medication that must be diluted and administered via an infusion pump to ensure precise control of the infusion rate. Rapid administration or IV push can cause fatal cardiac arrhythmias or arrest. Therefore, using a pump to deliver the medication slowly is the mandatory safety action to prevent toxicity.

✦ 台美臨床差異

在美國,氯化鉀輸注標準極為嚴格,通常需由藥局預先調配好濃度,且護理師在給藥前通常需要另一位護理師進行「雙重核對(Double check)」,以防止給藥錯誤。
