Which finding most strongly suggests that intracranial pressure is increasing?

Which finding most strongly suggests that intracranial pressure is increasing?

• A. Clear speech
• B. Hypertension
• C. Vomiting
• D. Loud crying

Answer: (C)

When intracranial pressure rises, the body often responds by triggering the vomiting center in the brainstem, producing vomiting. This reflex is a relatively direct signal that pressure inside the skull is increasing, making it a strong clue that ICP is climbing. Hypertension can occur with increased ICP as part of a late compensatory response, but it’s less specific and not as reliable a sign on its own. Clear speech shows that higher brain function is still intact, which argues against a significant ICP rise at that moment. Loud crying is a nonspecific reaction that can occur for many reasons and doesn’t specifically point to increased ICP. Vomiting, by contrast, more directly reflects pressure changes inside the cranial vault, so it’s the best indicator among the options.
