A client is prescribed furosemide 40 mg PO daily. Which assessment finding should the nurse prioritize during follow-up?
- ABlood glucose level血糖值
- BSerum creatinine level血清肌酸酐值
- CSerum potassium level✓ 正解血清鉀離子濃度
- DDaily dietary sodium intake每日膳食鈉攝取量
— Explanation · 中文詳解 —
呋塞米屬於環利尿劑（Loop diuretic），會促使鉀離子隨尿液大量排出，導致低血鉀。低血鉀會引起肌肉無力、心律不整，對心臟病人尤其危險。雖然此藥可能影響血糖或腎功能，但低血鉀的風險在臨床上最為急性且普遍，因此血鉀監測為首要。
Furosemide is a loop diuretic that promotes significant urinary excretion of potassium, leading to hypokalemia. Hypokalemia can cause muscle weakness and cardiac arrhythmias and is particularly dangerous in cardiac patients. Although the drug may also affect blood glucose or renal function, the risk of hypokalemia is the most acute and common clinically; therefore, monitoring serum potassium takes top priority.

兩地皆會定期監測電解質，但在台灣，病人的飲食順從性往往在衛教中被賦予極高優先級。
