Which of the following is an early sign of increased intracranial pressure?

Explanation:
Rising intracranial pressure first affects the brain’s ability to stay awake and aware. A change in responsiveness reflects early disruption of the reticular activating system and cortical function, so the patient may become confused, agitated, restless, or drowsy as ICP begins to rise. Pupillary changes, irregular respirations, and seizures tend to appear later as brainstem involvement or global deterioration progresses. So, a shift in level of consciousness is the earliest signal that ICP may be increasing, signaling the need for prompt evaluation and intervention.
