一位急性胰臟炎病人出現劇烈腹痛且 Trousseau's 徵象陽性。護理師應預期下列哪項檢驗結果？
A client with acute pancreatitis presents with severe abdominal pain and a positive Trousseau's sign. Which laboratory finding should the nurse anticipate?
- AHypomagnesemia低血鎂
- BHypocalcemia✓ 正解低血鈣
- CHyperkalemia高血鉀
- DHyponatremia低血鈉
— Explanation · 中文詳解 —
Trousseau's sign 是低血鈣的臨床徵象。急性胰臟炎時，壞死的胰臟脂肪釋放脂肪酸，與鈣離子結合形成皂化過程，導致血清鈣濃度降低。低血鈣會導致神經肌肉興奮性增加，出現手部痙攣（Trousseau's sign）或顏面神經跳動（Chvostek's sign）。
Trousseau's sign is a clinical sign of hypocalcemia. In acute pancreatitis, fatty acids released from necrotic pancreatic fat bind with calcium ions, forming a saponification process that reduces serum calcium levels. Hypocalcemia increases neuromuscular excitability, producing hand spasms (Trousseau's sign) or facial twitching (Chvostek's sign).
✦ 台美臨床差異
美台臨床對於急性胰臟炎的電解質監測一致，但護理師需在台灣執業中高度警覺此項併發症，因其常被誤認為單純脫水。
