The nurse is completing a neurological assessment on a client with a head injury. The Glasgow Coma Scale (GCS) score is 14. Which intervention should the nurse implement?

A. Prepare to give phenytoin IV as prescribed. Phenytoin is used for seizure prophylaxis in clients with moderate to severe head injuries (GCS ≤ 8–10). A GCS score of 14 indicates mild head injury, and prophylactic anticonvulsants may not be necessary unless ordered for specific risk factors. B. Perform a substernal rub to evoke a response to pain. A substernal rub (painful stimulus) is used to assess response in unconscious or unresponsive clients (GCS ≤ 8). With a GCS of 14, the client is alert or nearly fully conscious, making a painful stimulus unnecessary and inappropriate. C. Promptly notify the healthcare provider (HCP) of the GCS score. A GCS of 14 is not a critical or emergency finding, as it indicates mild neurological impairment. While the HCP should be updated on significant changes, routine monitoring is sufficient unless deterioration occurs. D. Continue monitoring the client's GCS score every 2 hours. Frequent neurological assessments are crucial in head injury management to detect worsening conditions like increasing intracranial pressure (ICP) or cerebral edema. Monitoring the GCS every 2 hours ensures timely intervention if the client’s condition changes.
