一位診斷為抗利尿激素分泌失調症候群（SIADH）的病人正在接受靜脈輸液，護理師應評估哪項指標以確認治療成效？
A client diagnosed with SIADH is receiving IV fluids. Which nursing assessment is most critical to evaluate the effectiveness of treatment?
- ASerum sodium level✓ 正解血清鈉（sodium）濃度
- BSkin turgor皮膚彈性
- CBlood pressure血壓
- DBowel sounds腸蠕動音
— Explanation · 中文詳解 —
SIADH 的核心病理在於水分滯留導致稀釋性低血鈉。治療目的為提升血清鈉濃度，因此監測血清鈉離子濃度是反映病況改善最直接、最客觀的指標。若血鈉未回升，表示水分滯留未改善，需調整輸液速率或加強藥物治療。
The core pathology of SIADH is water retention leading to dilutional hyponatremia. The aim of treatment is to raise the serum sodium concentration, so monitoring the serum sodium level is the most direct and objective indicator reflecting improvement of the condition. If serum sodium does not rise, water retention has not improved, and the infusion rate or pharmacologic therapy must be adjusted.
✦ 台美臨床差異
美國護理師常需監測高濃度鹽水（3% NaCl）輸注後的血鈉波動，台灣較少見高濃度鹽水給藥，多以限制水分攝取為主。
