護理師評估一位疑似氣胸的病人。下列哪項發現最需要立即回報給醫療提供者？
A nurse assesses a client with a suspected pneumothorax. Which finding is the most critical to report to the healthcare provider immediately?
- ADecreased breath sounds on the affected side患側呼吸音減弱
- BReports of sharp chest pain主訴劇烈胸痛
- CTracheal deviation toward the unaffected side✓ 正解氣管向未受影響側偏移
- DRespiratory rate of 24 breaths/min呼吸頻率 24 次/分
氣胸（Pneumothorax）若進展為張力性氣胸（Tension pneumothorax），胸膜腔內累積的氣體會產生極大壓力，導致縱膈腔偏移（Mediastinal shift），直接壓迫健側肺部並阻礙靜脈回流至心臟。氣管偏向健側（Tracheal deviation）是此危急生命的臨床特徵。護理師必須具備「ABC（氣道、呼吸、循環）」優先級判斷力，此發現代表循環與呼吸功能即將衰竭，需立即通知醫師進行減壓。
If a pneumothorax progresses to a tension pneumothorax, the accumulating air within the pleural space generates high pressure that produces a mediastinal shift, directly compressing the unaffected lung and impeding venous return to the heart. Tracheal deviation toward the unaffected side is a hallmark life-threatening clinical feature. The nurse must apply ABC (airway, breathing, circulation) prioritization; this finding indicates impending respiratory and circulatory collapse and requires immediate notification of the provider for decompression.
