A nurse cares for a client in the emergency department following a motor vehicle accident. Which assessment finding requires immediate follow-up by the nurse?

A. Tracheal deviation is a classic and life-threatening sign of a tension pneumothorax. In this condition, air accumulates in the pleural space and cannot escape, causing increased intrathoracic pressure. This pressure shifts mediastinal structures, including the trachea, away from the affected side. A tension pneumothorax can rapidly lead to respiratory distress, decreased venous return, shock, and cardiac arrest. This finding requires immediate intervention (such as needle decompression or chest tube placement). According to trauma priorities (Airway, Breathing, Circulation), airway and breathing issues always take precedence. B. Bruising may indicate blunt trauma and possible internal injury, such as rib fractures or pulmonary contusion. While this requires further evaluation, it is not immediately life-threatening unless accompanied by respiratory compromise. It does not take priority over a potentially fatal airway emergency. C. Headache and dizziness may indicate a concussion or mild traumatic brain injury. These symptoms require assessment and monitoring but are not immediately life-threatening unless accompanied by altered level of consciousness, unequal pupils, or neurological deficits. They do not supersede airway compromise. D. Superficial abrasions are minor soft tissue injuries. They require cleaning and monitoring for infection but are not urgent or life-threatening. They are the lowest priority among the options provided.
