Cushing's Triad presents with all of the following, except:

• A. Tachypnea
• B. Hypertension
• C. Bradycardia
• D. Irregular respirations

Answer: (A)

Cushing's triad reflects rising intracranial pressure and includes hypertension, bradycardia, and irregular respirations. The high intracranial pressure triggers a sympathetic surge that raises systolic blood pressure, the elevated pressure activates baroreceptors leading to a slower heart rate, and brainstem compression disrupts the respiratory centers, producing an irregular breathing pattern (often with pauses or alternating patterns like Cheyne-Stokes or ataxic breathing). Tachypnea, a fast regular respirations, does not fit this constellation, so it’s not part of the triad. When you see the triad, it signals a life-threatening rise in ICP requiring urgent management to lower pressure and protect brain function.
