一名急性胰臟炎病人有嚴重腹痛，護理師應優先監測哪項實驗室數據以防潛在致命併發症？
A client with acute pancreatitis presents with severe abdominal pain. Which laboratory finding should the nurse prioritize to monitor for potential life-threatening complications?
- ADecreased serum calcium✓ 正解血清鈣降低
- BElevated serum amylase血清澱粉酶升高
- CIncreased white blood cell count白血球計數增加
- DElevated serum glucose血清葡萄糖升高
急性胰臟炎常伴隨脂肪壞死，釋出的脂肪酸會與鈣離子結合形成鈣皂（Saponification），導致血鈣過低。低血鈣（Hypocalcemia）會引發嚴重的神經肌肉過度興奮，表現為手足搐搦（Tetany）、心律不整（如 QT 間期延長）甚至抽搐。這是胰臟炎死亡率增加的關鍵併發症，因此優先監測血鈣是護理的重中之重。
Acute pancreatitis is often accompanied by fat necrosis; the released fatty acids bind with calcium ions to form calcium soaps (saponification), leading to hypocalcemia. Hypocalcemia causes severe neuromuscular hyperexcitability, manifesting as tetany, cardiac dysrhythmias (such as prolonged QT interval), and even seizures. This is a key complication contributing to increased mortality in pancreatitis, so prioritizing the monitoring of serum calcium is the most critical nursing priority.
