A nurse is collecting data from a client who has fractured ribs. Which of the following is the priority finding the nurse should report to the provider

Rib fractures can lead to serious complications such as pneumothorax, hemothorax, and impaired ventilation due to pain and restricted chest expansion. These complications can rapidly progress to life-threatening conditions if not identified early. Priority nursing assessment focuses on recognizing signs of respiratory compromise and mediastinal shift. Early detection of deterioration is essential to prevent respiratory failure and ensure timely intervention. Rationale: A. Crepitus is a common finding in rib fractures caused by air escaping into subcutaneous tissues. It produces a crackling sensation on palpation and indicates subcutaneous emphysema. It should be documented and reported, but it is not the most immediately life-threatening finding compared to airway or mediastinal shift changes. B. Hypotension may occur with significant blood loss or tension pneumothorax but usually develops after more critical signs of respiratory compromise. Although concerning, it is typically a later manifestation of deterioration. Immediate airway and breathing abnormalities take higher priority in assessment. C. Tracheal deviation is a critical sign of tension pneumothorax, indicating shifting of mediastinal structures due to increased intrathoracic pressure. This can severely compromise venous return and cardiac output, leading to cardiovascular collapse if not treated immediately. It is a medical emergency requiring urgent intervention. D. Pain on inspiration is an expected finding with rib fractures due to movement of fractured bone ends during breathing. It contributes to shallow breathing and potential atelectasis, but it is not immediately life-threatening. Pain management is important but does not take priority over signs of respiratory or hemodynamic instability.
