一位急性胰臟炎病人主訴上腹劇痛，護理師評估發現 Chvostek 徵象呈陽性。需優先評估哪種電解質不平衡？

急性胰臟炎時，受損的胰臟釋放脂肪酶，導致腹腔內脂肪壞死，脂肪酸與鈣離子結合形成皂化反應（Saponification），引發低血鈣（Hypocalcemia）。Chvostek 徵象（叩擊臉部神經導致面部肌肉抽搐）是神經肌肉過度興奮的表現，常見於低血鈣。這是一種潛在的危險併發症，可能導致喉頭痙攣或心律不整，需優先評估與處置。

Acute pancreatitis can cause hypocalcemia due to saponification, where fatty acids bind with calcium during fat necrosis. A positive Chvostek sign indicates neuromuscular irritability associated with low calcium levels, which is a critical complication requiring immediate assessment to prevent severe outcomes like laryngospasm or arrhythmias.
