Answer: C."The earliest sign of increase intracranial pressure is a change in level of consciousness, especially a decrease in the level of consciousness. When intracranial pressure becomes too high, the brain can herniate. Cushing’s Triad are the 3 earliest signs of potential herniation. Bradycardia, bradypnea and a widened pulse pressure are the 3 signs of Cushing’s Triad. Remember that a pulse pressure is calculated by taking the systolic number and subtracting the diastolic. A normal is 30-50."
