病人診斷為抗利尿激素不適當分泌症候群（SIADH），應採取哪些護理措施？（選所有適合的）
A client is diagnosed with SIADH. Which nursing interventions should be implemented? (Select all that apply.)
- ARestrict oral fluid intake✓ 正解限制口服液體攝取
- BMonitor for weight gain✓ 正解監測體重增加
- CAdminister hypertonic saline as ordered✓ 正解依醫囑給予高張鹽水
- DEncourage a high-sodium diet鼓勵高鈉飲食
- EAssess for crackles in lung sounds✓ 正解評估肺部是否有囉音
SIADH（抗利尿激素不適當分泌症候群）導致水分滯留與稀釋性低血鈉。處理核心在於限水（restrict fluids），以減緩水分負荷與低血鈉。監測體重（weight gain）是評估水分滯留的重要指標；監測囉音（crackles）是評估肺水腫的指標。高張鹽水僅在嚴重低血鈉時使用。限水是維持生理穩定的最關鍵基礎。
SIADH (syndrome of inappropriate antidiuretic hormone secretion) causes fluid retention and dilutional hyponatremia. The cornerstone of management is fluid restriction to reduce fluid overload and the hyponatremia. Monitoring weight is an important indicator of fluid retention, and auscultating for crackles assesses for pulmonary edema. Hypertonic saline is used only for severe hyponatremia. Fluid restriction is the most critical foundation for maintaining physiological stability.
