一位急性胰臟炎病人的血鈣值為 7.2 mg/dL，護理師應優先監測哪項發現？
A client with acute pancreatitis presents with a serum calcium level of 7.2 mg/dL. Which finding is most relevant for the nurse to monitor?
- ADeep tendon hyperreflexia深部肌腱反射亢進
- BPositive Trousseau's sign✓ 正解特魯索氏徵象陽性
- CIncreased bowel sounds腸鳴音增加
- DFlattened T-waves on ECG心電圖上T波扁平
低血鈣常發生於急性胰臟炎，因脂肪皂化反應消耗鈣質。Trousseau's 徵象（測量血壓時手指抽搐）與 Chvostek's 徵象是低血鈣的神經肌肉過度興奮表現。B 為高血鉀或低血鉀特徵；C 非特異性；D 低血鈣導致神經肌肉興奮，雖可能引發反射亢進，但在急性期評估抽搐徵象具備更高診斷價值。
Hypocalcemia frequently occurs in acute pancreatitis because fat saponification consumes calcium. Trousseau's sign (carpopedal spasm during blood pressure measurement) and Chvostek's sign reflect the neuromuscular hyperexcitability of hypocalcemia. D is characteristic of potassium imbalance; C is nonspecific; D—hypocalcemia causes neuromuscular excitability that may produce hyperreflexia, but in the acute setting, assessment for tetany has greater diagnostic value.
台美臨床皆重視低血鈣引發的手足搐搦風險，護理師評估技能一致，需注意血清鈣值落差標準。
