病人獲醫囑給予靜脈注射氯化鉀 20 mEq 溶於 100 mL 生理食鹽水，並於 1 小時內輸完。護理師應優先採取的行動為何？
A client is prescribed intravenous potassium chloride (KCl) 20 mEq in 100 mL of 0.9% Normal Saline to be infused over 1 hour. What is the nurse's priority action?
- AMonitor the client's blood pressure every 15 minutes每 15 分鐘監測病人的血壓
- BAdminister the infusion via a central line透過中心靜脈導管輸注
- CAssess the client's urine output評估病人的尿液排出量
- DVerify the concentration and rate with a second nurse✓ 正解與第二位護理師核對濃度和輸注速率
KCl 是高警訊藥物（High-alert medication），極高的濃度或過快的給藥速率會引發心律不整甚至心搏停止。依據 ISMP 與安全給藥準則，給予高風險藥物前須進行雙重核對，確保劑量與輸注速率正確。其餘選項雖重要但皆排在安全核對之後。
Potassium chloride (KCl) is a high-alert medication; excessively high concentrations or overly rapid infusion can precipitate cardiac dysrhythmias or even cardiac arrest. According to ISMP and safe medication administration guidelines, an independent double-check must be performed before administering high-risk medications to ensure that both dose and infusion rate are correct. The other options are important but rank below safety verification.
美台臨床對於高警訊藥物皆採雙人核對，但美方對於 KCl 給藥速率的規範更為嚴謹。
