一位病人診斷為低血鈣。護理師應預期看到哪項評估結果？
A client is diagnosed with hypocalcemia. Which assessment finding should the nurse expect?
- APositive Chvostek's sign✓ 正解Chvostek 徵象陽性
- BHypoactive bowel sounds腸鳴音減弱
- CMuscle weakness肌肉無力
- DShortened QT interval on ECG心電圖上 QT 間期縮短
— Explanation · 中文詳解 —
低血鈣會增加神經肌肉興奮性。Chvostek 徵象（輕敲顏面神經引發面部抽搐）是低血鈣的神經肌肉過度激發表現。其他選項：高血鈣會導致腸蠕動減弱（Hypoactive bowel sounds）及 QT 間期縮短。
Hypocalcemia increases neuromuscular excitability, which can manifest as a positive Chvostek's sign when the facial nerve is tapped. Other options such as hypoactive bowel sounds, muscle weakness, and a shortened QT interval are typically associated with hypercalcemia.
