Which of the following best describes the Cushing's triad?

Cushing's triad is a late sign of rising intracranial pressure. When ICP increases, the body tries to maintain blood flow to the brain, which shows up as a rise in systolic blood pressure (hypertension). At the same time, the brainstem and cardiovascular reflexes respond with a slower heart rate (bradycardia). Respirations become irregular because the brainstem control of breathing is affected. Taken together, hypertension, bradycardia, and irregular respirations point to dangerous brain swelling and potential herniation, making this combination the best description of Cushing's triad. Other options don’t fit because they either mix in hypotension, tachycardia, or regular breathing, which are not characteristic of this triad. If you observe this pattern, treat as a medical emergency with rapid transport and continuous monitoring.
