A nurse is caring for a client who has a traumatic brain injury. Which of the following findings should the nurse identify as an indication of increased intracranial pressure (ICP)?

This scenario requires understanding neurovascular pathophysiology following head trauma. Knowledge of early versus late signs of intracranial pressure is essential to identify neurological deterioration and prevent brain herniation. Clinical assessment focuses on mental status changes and autonomic vital sign stability. Choice A rationale Tachycardia is typically not a sign of increased intracranial pressure. Instead, Cushing triad occurs as a late sign, characterized by bradycardia, widened pulse pressure, and irregular respirations as the brainstem undergoes significant compression and ischemia. Choice B rationale Amnesia is a common finding following traumatic brain injury due to localized tissue damage or concussion. However, it is a static deficit rather than a dynamic indicator of rising pressure within the rigid cranial vault. Choice C rationale Hypotension is not an indicator of increased intracranial pressure. In the Cushing response, the body increases systolic blood pressure to maintain cerebral perfusion pressure against the rising resistance of the swelling brain tissue and cerebrospinal fluid. Choice D rationale Restlessness is an early sign of increased intracranial pressure resulting from decreased cerebral oxygenation. As pressure rises, the brain becomes hypoxic, leading to agitation, irritability, and decreased level of consciousness before more severe physical signs manifest.
