The nurse is monitoring a 7-year-old child post-surgical resection of a supratentorial (cerebral) brain tumor. Which vital sign finding indicates Cushing's triad?
Explanation & Rationale
A. Increased temperature, tachycardia, tachypnea is not consistent with Cushing's triad. These signs generally reflect an infection, fever, or a stress response, and are not indicative of increased intracranial pressure (ICP) or brain herniation. B. Decreased temperature, bradycardia, bradypnea is incorrect. While bradycardia is a component of Cushing's triad, decreased temperature and bradypnea are not part of this syndrome. The signs of Cushing's triad typically include increased blood pressure, not decreased temperature. C. Bradycardia, high blood pressure, irregular respirations is correct. These are the hallmark signs of Cushing's triad, which indicate a significant increase in intracranial pressure. Bradycardia occurs as a result of elevated pressure on the brainstem, high blood pressure develops as a compensatory mechanism to maintain perfusion, and irregular respirations reflect brainstem dysfunction. D. Bradycardia, hypotension, tachypnea is incorrect. Hypotension is not part of Cushing's triad. Instead, high blood pressure is typically present in this condition due to the body's compensatory response to increased ICP.
