護理師準備靜脈給予氯化鉀（KCl）。下列哪項是必須核對的事項？
A nurse is preparing to administer potassium chloride IV to a client. Which of the following is essential for the nurse to verify?
- AThe client has an adequate urine output✓ 正解個案有足夠的尿量
- BThe client is on a clear liquid diet個案正在食用清流質飲食
- CThe client’s blood pressure is stable個案的血壓穩定
- DThe client has received a dose of loop diuretic個案已接受一劑環狀利尿劑
氯化鉀（KCl）是高警訊藥物（High-Alert Medication），其代謝主要依賴腎臟排泄。給藥前確認病人具備足夠的排尿量（通常建議每小時大於 30 mL）至關重要。若腎功能受損導致少尿或無尿，補充鉀離子將導致血鉀迅速飆升，引發致命性的心律不整（如心室顫動）。臨床思路應優先評估排泄功能，確保體內電解質平衡機制正常運作，以維護病人安全。
Potassium chloride (KCl) is a High-Alert Medication, and its excretion depends primarily on the kidneys. Confirming that the client has adequate urine output (generally recommended at greater than 30 mL per hour) before administration is critical. If renal impairment causes oliguria or anuria, potassium supplementation will cause serum potassium to rise rapidly, triggering fatal arrhythmias (such as ventricular fibrillation). The clinical priority should be assessing excretory function to ensure the body's electrolyte balance mechanisms are functioning normally and to maintain client safety.
