- ASerum potassium level✓ 正解血清鉀濃度
- BPeripheral edema周邊水腫
- CCapillary refill time微血管回充時間
- DBlood pressure血壓

Furosemide 為環利尿劑，會導致鉀離子經由尿液大量流失。在給予此類藥物前，護理師需確認血鉀數值，以避免嚴重低血鉀導致的心律不整。雖然血壓也很重要，但相較於低血鉀帶來的立即致死風險（如室性心律失常），血鉀監測在藥理治療指引中更具關鍵性。
Furosemide is a loop diuretic that causes substantial loss of potassium through the urine. Before administering this medication, the nurse must confirm the serum potassium value to avoid serious hypokalemia-induced arrhythmias. Although blood pressure is also important, monitoring serum potassium is more critical in the pharmacologic guidelines compared with the immediately life-threatening risks of hypokalemia (such as ventricular arrhythmias).
