A nurse is caring for a client with a traumatic brain injury in the ICU. The client’s intracranial pressure (ICP) is 22 mm Hg. Which intervention should the nurse implement first?

Choice A reason: IV mannitol reduces intracranial pressure by drawing fluid from brain tissue, but it requires a provider’s order and time to act. ICP of 22 mm Hg is elevated, and elevating the head of the bed is a non-invasive, immediate intervention to promote venous drainage, making it the priority action. Choice B reason: An ICP of 22 mm Hg indicates elevated intracranial pressure, risking brain herniation. Elevating the head of the bed to 30 degrees promotes cerebral venous drainage, reducing ICP immediately. This non-invasive intervention aligns with the ABCDE approach’s focus on preventing neurological deterioration, making it the first action in traumatic brain injury management. Choice C reason: Seizure prophylaxis prevents complications in traumatic brain injury but does not directly address elevated ICP (22 mm Hg). Seizures increase ICP further, but immediate pressure reduction is critical to prevent herniation. Head elevation is a faster, non-invasive intervention, making seizure prophylaxis secondary in this acute scenario. Choice D reason: Increasing sedation controls agitation, which can raise ICP, but it risks respiratory depression and requires careful monitoring. ICP of 22 mm Hg needs immediate reduction, and head elevation promotes venous drainage without delay. Sedation is a supportive measure, making it less urgent than positioning to lower ICP.
