抗利尿激素不適當分泌症候群（SIADH）病人，會出現哪些臨床評估結果？（選所有適合的）
Which assessment findings should a nurse expect in a client with SIADH? (Select all that apply.)
- ASerum sodium 125 mEq/L✓ 正解血清鈉離子125 mEq/L
- BSerum osmolality 295 mOsm/kg血清滲透壓295 mOsm/kg
- CUrine specific gravity 1.030✓ 正解尿液比重的1.030
- DWeight gain without edema✓ 正解無水腫的體重增加
- EDecreased blood pressure血壓下降
抗利尿激素不適當分泌症候群（SIADH）會導致身體分泌過多的抗利尿激素，造成過多的水分滯留，進而稀釋血液中的鈉離子，導致低血鈉。臨床表現包括血清鈉濃度降低、尿液因水分重吸收而變得高度濃縮（尿比重升高）。由於身體滯留水分，病人會出現體重增加，但因為水份分佈在血管內外，臨床上通常不會觀察到明顯的水腫。護理師需監測體液平衡與神經學症狀。
Syndrome of inappropriate antidiuretic hormone secretion (SIADH) results in excessive secretion of antidiuretic hormone, causing excessive water retention that dilutes serum sodium and leads to hyponatremia. Clinical features include decreased serum sodium concentration and concentrated urine (elevated urine specific gravity) due to water reabsorption. Because of water retention, the client experiences weight gain, but because the water is distributed between the intra- and extravascular compartments, marked edema is generally not observed. The nurse should monitor fluid balance and neurologic symptoms.
