NREMT Advanced-EMT Practice Test

This question focuses on recognizing Cushing's Triad, a late sign of increasing intracranial pressure. The triad consists of elevated arterial pressure (often with a wide pulse pressure), irregular or slowed breathing, and a slowed heart rate (bradycardia). The best choice reflects all three: increased blood pressure, irregular breathing, and a decreased heart rate. This combination fits the classic pattern produced by brainstem compression and impaired autonomic regulation as ICP rises. Other patterns don’t fit because they show hypotension with tachycardia or normal/regular breathing, which are not consistent with the sympathetic response and brainstem dysfunction seen in rising ICP. Recognizing this triad signals urgent need to manage intracranial pressure to prevent further deterioration.
