A patient with IICP shows signs of the Cushing's triad. Which of the following is NOT typically part of this triad?

A. Irregular respirations is incorrect because irregular or abnormal breathing patterns, such as Cheyne-Stokes or ataxic respirations, are part of Cushing’s triad. These occur due to pressure on the brainstem and impaired respiratory control. B. Fever is correct because fever is not a component of Cushing’s triad. While fever may occur in neurological injury due to hypothalamic dysfunction or infection, it is not a defining feature of the triad. Including fever as part of the triad would be incorrect. C. Bradycardia is incorrect because a slowed heart rate is a classic component of Cushing’s triad. It develops as a compensatory response to increased intracranial pressure and rising systolic blood pressure. D. Increased systolic blood pressure is incorrect because hypertension with widened pulse pressure is another hallmark of Cushing’s triad. This occurs as a compensatory mechanism to maintain cerebral perfusion in the setting of elevated ICP.
