病人正接受氯化鉀 20 mEq 溶於 100 mL 生理食鹽水的靜脈輸注。給藥前最重要的護理措施為何？
A client is receiving an IV infusion of Potassium Chloride 20 mEq in 100 mL of 0.9% Normal Saline. What is the most critical nursing action before administration?
- AVerify the concentration and infusion rate✓ 正解確認濃度與輸注速率
- BCheck the client's latest serum potassium level檢查病人最新的血清鉀離子濃度
- CEnsure the IV site is free of phlebitis確保靜脈穿刺處無靜脈炎跡象
- DAssess the client's hourly urine output評估病人每小時尿量
靜脈注射鉀離子具有極高危險性。根據安全給藥標準，護理師應優先確保輸注濃度與速度符合安全指引，以預防心律不整及局部組織壞死。未經稀釋的鉀離子絕對不可靜脈推注（IV push）。儘管監測尿量（D）與電解質（B）重要，但確保給藥參數的正確性是避免立即性醫療失誤的首要防線。
Intravenous potassium is a high-alert medication that requires strict verification of concentration and infusion rate to prevent fatal arrhythmias and tissue damage. Rapid administration or incorrect concentrations can lead to severe complications, making this the priority safety check. While renal function and IV site assessment are important, verifying infusion parameters is the immediate safeguard against medication errors.
台美皆將鉀離子靜脈輸注列為高警訊藥物（High-Alert Medication），需雙人核對（Double check）。
