Cushing's Triad is best described as which of the following?

• A. Increased Systolic Pressure
• B. Widened Pulse Pressure
• C. Decreased Pulse and Respiratory Rate
• D. All of the above

Answer: (D)

Cushing's Triad signals rising intracranial pressure and is marked by three interrelated changes. The body responds to increased ICP with higher systolic blood pressure while the diastolic value may stay the same or fall, producing a widened pulse pressure. The brainstem’s reflexes slow the heart, causing bradycardia. Respirations become irregular or depressed as brainstem compression progresses. Because all of these features can appear together, the best answer is all of the above. Remember, this triad is a late, emergency sign of dangerous ICP and requires rapid airway, breathing, and circulation management to prevent herniation.
