Which finding can indicate intracranial pressure elevation?

• A. Pupil equal and reactive
• B. Normal mental status
• C. Stable vital signs
• D. Pupil changes, unequal or dilated

Answer: (D)

Rising intracranial pressure often affects the brainstem pathways that control the pupils, so changes in pupil size or reactivity can be an early and important sign. Unequal or dilated pupils indicate that the oculomotor nerve is being impacted, which can occur with ICP elevation and even signal a risk of herniation if it worsens. This makes the finding of pupil changes the most pertinent clue among the options. By contrast, a pupil that is equal and reactive is typically a normal finding and does not point specifically to increased ICP. Normal mental status or stable vital signs can occur for various reasons and do not reliably reflect ICP levels, whereas the presence of pupil abnormalities provides a clearer, more immediate cue to assess and address potential intracranial hypertension.
