護理師準備對低血鉀病人靜脈輸注氯化鉀（KCl），哪項護理措施對病人安全至關重要？
A nurse is preparing to administer IV potassium chloride (KCl) to a client with hypokalemia. Which nursing action is essential for patient safety?
- AAdminister the medication via an IV push經靜脈推注給藥
- BAssess urine output before administering✓ 正解給藥前評估尿液排出量
- CVerify the medication is diluted in at least 100 mL of fluid確認藥物已稀釋於至少 100 mL 液中
- DInfuse at a rate of 40 mEq/hour以 40 mEq/小時 速率輸注
靜脈輸注鉀離子前，必須確認腎功能正常。若病人無尿或少尿（<30 mL/hr），輸鉀會導致致死性高血鉀。選項 A 會導致心臟驟停；選項 C 應確認稀釋濃度而非僅看總量；選項 D 輸注速率過快（一般建議周邊不超過 10mEq/hr），極具危險性。
Before administering IV potassium, normal renal function must be verified. If the client is anuric or oliguric (< 30 mL/hr), potassium administration will lead to lethal hyperkalemia. Option A would cause cardiac arrest; option C should focus on confirming the dilution concentration rather than only the total amount; option D, an excessive infusion rate (generally peripheral infusion should not exceed 10 mEq/hr), is extremely dangerous.
台灣針對高濃度鉀離子給藥有更嚴格的雙重核對與獨立給藥規定，臨床常備有預混液以降低調配失誤。
