護理師準備為病人靜脈輸注氯化鉀。下列哪項措施對護理師而言是必要的？
A nurse is preparing to administer potassium chloride intravenously to a client. Which of the following actions is essential for the nurse to implement?
- ACheck the client's blood pressure every 5 minutes每 5 分鐘測量病人的血壓
- BPerform the procedure using a gravity drip set使用重力滴注組執行此程序
- CEnsure the medication is diluted in a solution✓ 正解確保藥物已稀釋於溶液中
- DAdminister the medication via IV push經靜脈推注給予藥物
靜脈輸注鉀離子（KCl）具有高度風險，絕對不可直接靜脈推注（IV Push）。高濃度鉀離子會直接導致心律不整與心跳停止。臨床上必須將鉀離子稀釋在靜脈輸液中，並使用輸液幫浦（Infusion pump）精確控制滴速。執行前需確認病人的尿量（確認腎功能），並嚴格遵守安全濃度限制，以防止靜脈炎或高血鉀發生。
Intravenous administration of potassium (KCl) carries a high level of risk, and IV push is absolutely contraindicated. Concentrated potassium can directly cause arrhythmias and cardiac arrest. Clinically, potassium must be diluted in IV fluid, and an infusion pump must be used to precisely control the infusion rate. Before administration, the nurse should verify the client's urine output (to confirm renal function) and strictly adhere to safe concentration limits to prevent phlebitis or hyperkalemia.
