A man brings his wife to the emergency department (ED) because she is confused and restless. He tells the nurse that they were in a motor vehicle collision early today and his wife bumped her head on the dashboard. The husband is very concerned about his wife and refuses to leave her bedside. Which intervention is most important for the nurse to implement?

Rationale: A. Orient the client to her surroundings: While orientation is helpful for confusion, the client’s restlessness and confusion could indicate increasing intracranial pressure or cerebral bleeding, which require immediate physical assessment rather than reassurance. B. Allow husband to stay at bedside: Allowing the husband to remain can provide emotional support, but this is not the priority when assessing for potentially life-threatening neurological changes. Emotional comfort is secondary to detecting and managing complications of head trauma. C. Implement seizure precautions: Seizure precautions are appropriate for clients with head injuries but should follow a focused neurological assessment. Detecting cerebrospinal fluid (CSF) leakage or signs of skull fracture takes precedence because it indicates a severe brain injury requiring urgent intervention. D. Assess for drainage from ears or nose: Clear or bloody drainage may indicate CSF leakage due to a basilar skull fracture. Identifying this finding early is critical to prevent infection, monitor for increased intracranial pressure, and guide emergent management, making this the most important immediate nursing action.
