護理師準備給予氯化鉀靜脈注射，哪項行動對於確保病人安全至關重要？
A nurse is preparing to administer potassium chloride IV. Which action is essential to ensure client safety?
- ACheck the client's blood pressure every 5 minutes每5分鐘測量病人的血壓
- BEnsure the client has a peripheral IV site only確保病人僅有周邊靜脈留置針
- CAdminister as a bolus to ensure quick correction作為推注以確保快速糾正
- DVerify the concentration and infusion rate via a pump✓ 正解透過幫浦驗證濃度與輸注速率
— Explanation · 中文詳解 —
氯化鉀（Potassium chloride）是高警訊藥物（High-alert medication）。若給予速度過快或濃度過高，會直接導致嚴重的心律不整，甚至引發心跳停止。因此，臨床上必須透過輸液幫浦（Infusion pump）精確控制滴速。嚴禁以靜脈推入（Bolus）方式給藥，且應避免從極細小的周邊靜脈以高濃度給予，以免造成嚴重的血管刺激與組織壞死。
Potassium chloride is a high-alert medication. If given too rapidly or at too high a concentration, it can directly cause severe cardiac dysrhythmias, including cardiac arrest. Therefore, the infusion rate must be precisely controlled with an infusion pump. IV bolus administration is strictly contraindicated, and giving high concentrations through a very small peripheral vein should also be avoided to prevent severe venous irritation and tissue necrosis.
