護理師正在照護一位副甲狀腺功能低下症（hypoparathyroidism）病人。哪項評估發現需要立即介入？
A nurse is caring for a client with hypoparathyroidism. Which assessment finding requires immediate intervention?
- APositive Chvostek's signChvostek 徵象陽性
- BMuscle cramps and tetany肌肉痙攣與手足搐搦
- CNumbness and tingling in the fingers手指麻木與刺痛感
- DLaryngospasm✓ 正解喉痙攣
副甲狀腺功能低下導致血鈣下降，可引起神經肌肉興奮性增強。Chvostek's sign、手指麻刺感、肌肉痙攣和肌腱抽搐（tetany）都是低血鈣的表現。然而，喉部痙攣（laryngospasm）是最危險的表現，會導致呼吸道阻塞，需要立即處理，可能包括給予鈣離子補充和維持呼吸道通暢。
Hypoparathyroidism leads to decreased serum calcium, which can cause increased neuromuscular excitability. Positive Chvostek's sign, numbness and tingling in the fingers, muscle cramps, and tetany are all manifestations of hypocalcemia. However, laryngospasm is the most dangerous manifestation, as it can lead to airway obstruction and requires immediate intervention, which may include calcium supplementation and maintaining airway patency.
美國的內分泌科和急診科對於低血鈣危象有標準的處理流程；台灣也遵循國際準則，但病人對早期喉部緊縮感的警覺性以及醫療體系的快速反應是關鍵。
