一位急性胰臟炎病人在輸液治療中。護理師在測量血壓時發現特魯索氏徵象（Trousseau's sign）。護理師應懷疑何種電解質不平衡？
A client with acute pancreatitis is receiving IV fluids. The nurse notes Trousseau's sign during blood pressure measurement. Which electrolyte imbalance should the nurse suspect?
- AHyponatremia低血鈉症
- BHypermagnesemia高血鎂症
- CHyperkalemia高血鉀症
- DHypocalcemia✓ 正解低血鈣症
急性胰臟炎（Acute Pancreatitis）因脂肪壞死，釋放出的脂肪酸會與鈣離子結合，導致低血鈣（Hypocalcemia）。Trousseau's sign（加壓上臂後出現手部抽搐）是低血鈣的神經肌肉過度興奮典型表徵。護理師需警覺此現象，因為嚴重低血鈣會引發喉痙攣（laryngospasm）或癲癇，危及呼吸道安全。
In acute pancreatitis, fat necrosis releases free fatty acids that bind calcium ions, leading to hypocalcemia. Trousseau's sign (carpal spasm after inflating a blood pressure cuff on the upper arm) is a classic manifestation of neuromuscular hyperexcitability due to hypocalcemia. The nurse must remain alert for this finding because severe hypocalcemia can precipitate laryngospasm or seizures, threatening airway safety.
