護理師照顧一位 SIADH（抗利尿激素分泌不適當症候群）病人，下列哪些發現是預期中的？（選所有適合的）
A nurse is caring for a client with SIADH. Which findings should the nurse expect? (Select all that apply.)
- ASerum sodium 125 mEq/L✓ 正解血清鈉 125 mEq/L
- BUrine specific gravity 1.002尿液比重 1.002
- CWeight gain without edema✓ 正解體重增加但無水腫
- DSerum osmolality 260 mOsm/kg✓ 正解血清滲透壓 260 mOsm/kg
- EDecreased urine output✓ 正解尿量減少
抗利尿激素分泌不適當症候群（SIADH）會導致體內水分過度滯留，進而稀釋血液中的電解質。臨床表現包括稀釋性低血鈉（Hyponatremia）、血滲透壓降低、尿量減少（因水分滯留）以及尿液濃縮（尿滲透壓升高）。體重會因水分滯留而增加，但因為水分進入細胞內導致水腫，外觀上通常不會出現明顯的周邊凹陷性水腫。
Syndrome of inappropriate antidiuretic hormone secretion (SIADH) causes excessive water retention in the body, which in turn dilutes electrolytes in the blood. Clinical features include dilutional hyponatremia, decreased serum osmolality, decreased urine output (due to water retention), and concentrated urine (increased urine osmolality). Body weight rises because of water retention, but since the water shifts into the intracellular compartment causing cellular edema, obvious peripheral pitting edema is usually not seen on inspection.
