— Explanation · 中文詳解 —
Furosemide 是排鉀利尿劑，容易引起低血鉀，這會顯著增加地高辛中毒風險並導致心律不整。給藥前確認鉀離子濃度是臨床常規，若鉀低於正常範圍應暫停給藥並通知醫師。雖然肌酸酐與鈉離子也重要，但心律不整的致命風險性更高。
Furosemide is a potassium-wasting loop diuretic that significantly increases the risk of hypokalemia and life-threatening cardiac arrhythmias. Checking serum potassium levels before administration is critical to prevent complications, especially in clients with heart failure.
✦ 台美臨床差異
美國護理師依據 protocol 具備更高度的判斷權，可依檢驗值自主決定是否給藥；台灣常規較依賴醫師醫囑調整。
