護理師正在監測甲狀腺切除術後的病人。哪項發現提示有低血鈣？
The nurse is monitoring a client who had a thyroidectomy. Which finding suggests hypocalcemia?
- ANegative Chvostek's signChvostek氏徵象呈陰性
- BTingling or numbness in the fingers✓ 正解手指刺痛或麻木
- CFlaccid paralysis弛緩性麻痺
- DHyporeflexia反射減弱
甲狀腺切除術 (thyroidectomy) 後，病人有發生低血鈣 (hypocalcemia) 的風險，這是因為手術中可能不慎損傷或切除鄰近的副甲狀腺 (parathyroid glands)。副甲狀腺負責分泌副甲狀腺素 (parathyroid hormone, PTH)，調節血鈣水平。當副甲狀腺功能受損時，PTH 分泌不足，導致血鈣降低。低血鈣會增加神經肌肉的興奮性，早期症狀通常表現為感覺異常，如手指、腳趾或嘴唇周圍的麻木和刺痛感 (tingling or numbness in the fingers)。護理師應密切監測這些早期症狀，因為嚴重低血鈣可能進展為手足抽搐 (tetany)、肌肉痙攣甚至喉痙攣，危及生命。及早發現並處理低血鈣是術後護理的優先事項。
Hypocalcemia is a common complication following thyroidectomy due to potential damage to the parathyroid glands. Early signs include paresthesia, such as tingling or numbness in the fingers, toes, or around the mouth, resulting from increased neuromuscular excitability.
美國護理師在甲狀腺術後必備「Calcium Gluconate」在床邊備用；台灣醫院通常也列為常備藥但可能存放在急救車或護理站藥櫃。
