What should the nurse do when new dilation of the pupils and a sluggish response to light occur in a patient with brain injury?

• A. Notify the health care provider immediately
• B. Administer a sedative
• C. Increase oral fluids
• D. Check blood glucose

Answer: (A)

New dilation of the pupils with a sluggish response to light after brain injury is a dangerous neurologic change signaling possible increased intracranial pressure and risk of brain herniation. Because this can escalate quickly, the nurse should notify the health care provider immediately so urgent evaluation and potential interventions can be started. In the meantime, continue close neuro monitoring, document the exact pupil sizes and reactivity, and maintain the patient’s airway and breathing. Avoid actions that could worsen intracranial pressure, such as unnecessary agitation or maneuvers; keep the patient appropriately positioned and the environment calm. While checking glucose and other routine checks are important, they won’t address this emergent sign as directly as prompt medical assessment and intervention.
