Which triad describes hypertension, bradycardia, and irregular respirations?

• A. Cushing Triad
• B. Decorticate Posturing
• C. Aura
• D. Intracranial Pressure

Answer: (A)

Recognizing signs of increased intracranial pressure is tested here. The combination of hypertension, bradycardia, and irregular respirations is classic for Cushing triad, a reflex aimed at preserving cerebral perfusion when ICP rises. The high blood pressure helps push blood into the brain, while the baroreceptors respond with a slowed heart rate (bradycardia). Brainstem involvement from the pressure often produces irregular breathing patterns. Together, these signs indicate elevated ICP and potential risk of brain herniation, requiring urgent assessment.

The other options don’t match this specific triad: decorticate posturing is a motor abnormality, aura is a sensory phenomenon preceding seizures, and intracranial pressure describes the condition itself rather than a triad of signs.
