護理師照護急性腎衰竭病人。哪項發現顯示病人進入多尿期（Diuretic phase）？
A nurse is caring for a patient with acute renal failure. Which finding indicates the patient is in the diuretic phase?
- AIncrease in serum potassium levels血清鉀濃度上升
- BRapid decline in serum creatinine levels血清肌酸酐濃度迅速下降
- CSudden onset of oliguria突發少尿
- DGradual increase in daily urine output✓ 正解每日尿液排出量逐漸增加
— Explanation · 中文詳解 —
多尿期（Diuretic phase）特徵為尿量開始逐漸增加，但腎絲球濾過率尚未完全恢復，導致尿液濃縮能力差。此階段重點在於預防脫水與電解質失衡。肌酸酐下降代表腎功能改善，而非多尿期的定義。少尿期才是尿量減少的時期。
The diuretic phase is characterized by a gradual increase in urine output, although the glomerular filtration rate has not yet fully recovered, so the kidneys cannot concentrate urine well. The focus of care during this phase is preventing dehydration and electrolyte imbalance. A falling creatinine reflects improving renal function rather than defining the diuretic phase. Oliguria characterizes the initiation phase, not the diuretic phase.
