護理師準備靜脈輸注氯化鉀，下列哪項措施對病人安全至關重要？
A nurse is preparing to administer potassium chloride intravenously. Which of the following actions is essential for client safety?
- AEnsure the concentration does not exceed 10 mEq/100 mL.確保濃度不超過 10 mEq/100 mL
- BInfuse the medication over 15 minutes.在 15 分鐘內輸注藥物
- CAssess for a urine output of at least 30 mL/hour.✓ 正解評估尿液輸出量是否至少為 30 mL/小時
- DAdminister the medication via an IV push injection.透過靜脈推注給藥
鉀離子輸注前必須確認腎功能正常，因鉀離子若無法排出會導致高血鉀與心律不整。尿量至少 30 mL/hr 是判斷腎功能是否能承受鉀負荷的關鍵指標。氯化鉀絕對禁止直接靜脈推注，且必須嚴格稀釋，過快輸入會造成心臟驟停。
Before infusing potassium, renal function must be confirmed to be adequate, because potassium is excreted primarily by the kidneys. If the patient is anuric or oliguric, administering potassium can lead to dangerous hyperkalemia and arrhythmias. A urine output of at least 30 mL/hr is the key indicator that renal function can handle a potassium load. Potassium chloride is absolutely contraindicated as a direct IV push, must be strictly diluted, and rapid administration can cause cardiac arrest.
