Furosemide 是環利尿劑，會導致鉀離子隨尿液排出。低血鉀症（hypokalemia）是其主要副作用，且會增加 digoxin 毒性及引發嚴重心律不整。給藥前確認血鉀濃度為必要的安全評估，以確保電解質平衡。若鉀數值低於 3.5 mEq/L，通常需先暫停給藥並通知醫師，這是護理安全中的標準步驟。
Furosemide is a loop diuretic that significantly increases renal excretion of potassium, creating a risk for hypokalemia. Low serum potassium levels can lead to serious cardiac dysrhythmias and increase the risk of digoxin toxicity. Therefore, checking the serum potassium level is the most critical assessment prior to administration to ensure client safety.
