— Explanation · 中文詳解 —
Furosemide 是排鉀利尿劑，會導致血鉀進一步下降。正常血鉀範圍為 3.5-5.0 mEq/L，病人的 3.2 mEq/L 屬於低血鉀，此時給藥恐引發嚴重的心律不整，故應暫停並聯繫醫師討論補鉀或調整劑量。
Furosemide is a loop diuretic that promotes potassium excretion, which can exacerbate existing hypokalemia. Since the client's potassium level is 3.2 mEq/L, below the normal range of 3.5 to 5.0 mEq/L, administering the medication could precipitate dangerous cardiac arrhythmias. The nurse should hold the dose and notify the provider to address the electrolyte imbalance before proceeding with diuretic therapy.
