Following a motorcycle vehicle collision, an adult client can follow simple commands, but is oriented only to self. The client was not wearing a helmet at the time of the accident, and is exhibiting periorbital bruising with bloody drainage from both ears. Which assessment finding should the nurse identify as a life threatening condition?

Rationale: A. Rib pain with deep inspiration: Rib pain suggests possible rib fracture or contusion, which can be painful but is not immediately life threatening unless accompanied by respiratory compromise or pneumothorax. It requires monitoring but not urgent life-saving action. B. Diminished bilateral breath sounds: Decreased breath sounds on both sides may indicate a severe chest injury such as pneumothorax, hemothorax, or respiratory failure. This finding threatens oxygenation and ventilation, requiring immediate airway management and possibly chest tube insertion. C. Generalized abdominal tenderness: While abdominal tenderness raises concern for internal bleeding or organ injury, it does not immediately impair ventilation or perfusion. It is serious but not as acutely life threatening as compromised breath sounds. D. Nausea with projectile vomiting: Projectile vomiting may suggest increased intracranial pressure from head trauma, but the airway and breathing take priority. Airway obstruction or hypoxia from inadequate ventilation remains the most immediate life-threatening condition.
