一位急性胰臟炎病人，血清鈣濃度為 7.2 mg/dL。護理師評估時應優先注意哪項發現？
A client with acute pancreatitis presents with a serum calcium level of 7.2 mg/dL. Which finding should the nurse prioritize during assessment?
- AElevated blood glucose血糖升高
- BPositive Trousseau sign✓ 正解Trousseau 徵象陽性
- CDeep tendon hyperreflexia深層肌腱反射亢進
- DHypoactive bowel sounds腸鳴音減弱
急性胰臟炎病人常因脂肪皂化（Fat saponification）導致鈣離子沉積，進而引發低血鈣。低血鈣會增加神經肌肉激惹性，臨床上需評估 Trousseau 徵象（充氣血壓計導致手腕痙攣）與 Chvostek 徵象（敲擊面神經導致臉部肌肉抽動）。這些徵象預示著潛在的癲癇或喉部痙攣風險，必須優先處理。
Clients with acute pancreatitis often develop hypocalcemia because of fat saponification, in which calcium ions become deposited in necrotic fat. Hypocalcemia increases neuromuscular irritability, and the nurse should assess for Trousseau's sign (carpal spasm induced by a blood pressure cuff) and Chvostek's sign (facial muscle twitching with tapping over the facial nerve). These signs herald a risk of seizures or laryngospasm and must be addressed as the priority.
