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. Observe vital signs sequences as a way of assessing for Cushing's triad. Cushing’s triad (hypertension with widened pulse pressure, bradycardia, and irregular respirations) is a late sign of increased intracranial pressure (ICP). While monitoring for it is important, early recognition and direct ICP monitoring are more effective in preventing deterioration.
B. Evaluate hourly urinary output. Mannitol is an osmotic diuretic that can cause significant diuresis, requiring close monitoring of urine output to prevent dehydration and electrolyte imbalances. However, assessing ICP is the priority because increased ICP can cause brain herniation, which is life-threatening.
C. Monitor arterial blood pressure. Dopamine is a vasopressor used to maintain cerebral perfusion pressure (CPP), which is crucial in head injury management. While blood pressure monitoring is essential, directly assessing ICP ensures that treatment is effective in preventing secondary brain injury.
D. Assess intracranial pressure following intracranial transducer placement. The highest priority is monitoring ICP immediately after placement to detect dangerous elevations that could lead to herniation. The intraventricular catheter provides real-time pressure readings, guiding interventions like mannitol administration and blood pressure control to optimize cerebral perfusion and prevent worsening neurological damage.

A. Allow the family to touch and talk to the client. Family presence can provide emotional support for both the client and loved ones. Even though the client is sedated and has a low GCS, familiar voices and touch may reduce stress and anxiety. Allowing family interaction fosters comfort and connection during a critical time.
B. Reassess the client's vascular access. Maintaining secure and functional vascular access is essential for administering fluids, medications, and emergency interventions. Before transport, the nurse should confirm IV patency, ensure secure connections, and assess for signs of infiltration or malfunction. Trauma patients may require additional or larger bore IV access for fluid resuscitation or transfusion.
C. Assess neurological vital signs every 15 minutes. Frequent neurological assessments are crucial in head trauma patients with a low GCS to monitor for signs of worsening intracranial pressure, cerebral edema, or herniation. Changes in pupil response, motor function, or vital signs may indicate neurological deterioration requiring urgent intervention. Monitoring trends over time is necessary for early detection of complications.
D. Administer ophthalmic ointment. Clients with a low GCS often have impaired blinking, placing them at risk for corneal abrasions and dryness. Applying ophthalmic lubricant or artificial tears protects the cornea from injury and promotes eye health. Preventing exposure keratitis is essential in unconscious or sedated clients to avoid long-term ocular damage.
E. Apply soft bilateral wrist restraints for transport. Restraints are unnecessary because the client is sedated, intubated, and has a GCS of 6, meaning they cannot attempt self-extubation or interfere with care. Restraints should only be used if the client demonstrates a risk of harm. Standard transport protocols prioritize sedation and safety measures over restraints unless specifically required.
