Which change in status should alert the nurse to increased intracranial pressure (ICP) in a child with a head Injury?

A. Rapid, shallow breathing: Changes in respiratory pattern can occur with anxiety, pain, or respiratory compromise and are not specific indicators of increased intracranial pressure. ICP-related respiratory changes typically involve irregular or decreased respirations as brainstem compression develops. This finding alone does not reliably signal rising ICP. B. Irregular, rapid heart rate: An irregular or rapid heart rate may be associated with pain, fever, hypoxia, or stress. With increased intracranial pressure, the classic cardiovascular response is bradycardia rather than tachycardia. C. Increased diastolic pressure with narrowing pulse pressure: Increased intracranial pressure is associated with widening pulse pressure due to rising systolic pressure and falling diastolic pressure. Narrowing pulse pressure suggests hypovolemia or shock rather than ICP elevation. This finding does not align with Cushing’s triad. D. Confusion and altered mental status: Changes in level of consciousness are the earliest and most sensitive indicators of increased intracranial pressure in children. Confusion, restlessness, and altered responsiveness reflect impaired cerebral perfusion. Prompt recognition of these neurologic changes is critical to prevent further brain injury.
