一名急性胰臟炎病人出現嚴重腹痛與噁心，護理師發現 Chvostek 徵象呈現陽性。護理師應優先關注哪項實驗室數值？
A client with acute pancreatitis presents with severe abdominal pain and nausea. The nurse notes a positive Chvostek sign. Which laboratory value should the nurse prioritize?
- ASerum lipase血清脂解酶 (Serum lipase)
- BSerum glucose血清葡萄糖 (Serum glucose)
- CSerum potassium血清鉀 (Serum potassium)
- DSerum calcium✓ 正解血清鈣 (Serum calcium)
急性胰臟炎（Acute Pancreatitis）會導致胰臟釋放酵素，造成腹部周圍脂肪組織分解，此過程稱為「脂肪皂化（Fat Saponification）」。脂肪酸會與血清鈣結合形成不溶性的鈣皂，導致血鈣濃度下降（低血鈣）。Chvostek 徵象陽性（輕敲臉部神經導致肌肉抽搐）與 Trousseau 徵象陽性皆為低血鈣引起的 neuromuscular irritability（神經肌肉興奮性）表現。低血鈣可能誘發致命性的喉頭痙攣或心律不整，因此在臨床照護中，監測電解質平衡是維護病人生命安全的首要任務。
In acute pancreatitis, the release of pancreatic enzymes causes breakdown of fat in surrounding tissues, a process called fat saponification. Free fatty acids bind serum calcium to form insoluble calcium soaps, resulting in decreased serum calcium (hypocalcemia). A positive Chvostek sign (twitching of facial muscles upon tapping over the facial nerve) and a positive Trousseau sign are both manifestations of neuromuscular irritability caused by hypocalcemia. Hypocalcemia may precipitate life-threatening laryngospasm or cardiac arrhythmia; therefore, monitoring electrolyte balance is the priority for patient safety.
