一位急性胰臟炎病患出現嚴重腹痛及 Trousseau's 徵象陽性，護理師應優先檢查哪項數據？
A client with acute pancreatitis presents with severe abdominal pain and a positive Trousseau's sign. Which laboratory value should the nurse prioritize?
- ASerum amylase血清澱粉酶
- BSerum calcium✓ 正解血清鈣
- CSerum potassium血清鉀
- DSerum glucose血清葡萄糖

急性胰臟炎常見脂肪壞死與鈣離子結合，導致低血鈣。Trousseau's 徵象（測量血壓時手指抽搐）即為低血鈣的特異性徵象。監測鈣離子能預防喉痙攣或心律不整等危及生命之併發症，較澱粉酶或血糖指標更具立即生命威脅預測價值。
In acute pancreatitis, fat necrosis binds calcium (saponification), causing hypocalcemia. A positive Trousseau's sign (carpal spasm with BP cuff inflation) is a specific marker of hypocalcemia. Monitoring calcium prevents life-threatening laryngospasm or arrhythmias and carries higher immediate predictive value than amylase or glucose.
✦ 台美臨床差異
美國護理師常需負責採血或自主判讀數據變異，台灣則多由檢驗科回報，護理師依醫囑處理。
