What vital sign change is typical in Increased Intracranial Pressure (ICP) as described?

• A. Decreased BP
• B. Increased pulse
• C. Decreased respirations
• D. Increased BP

Answer: (D)

Increased Intracranial Pressure (ICP) often leads to a condition known as Cushing's triad, which is characterized by a specific pattern of vital sign changes. One of the hallmark signs of this condition is an increase in blood pressure. This occurs as a compensatory mechanism in response to elevated intracranial pressure, as the body attempts to ensure adequate cerebral perfusion despite the increased pressure within the skull.

As ICP rises, the body can respond by increasing systemic vascular resistance, which raises blood pressure in an effort to maintain cerebral blood flow. This response is crucial since, if the brain does not receive enough blood flow, it can lead to further neurological damage.

While the other choices may depict changing vital signs under various circumstances, they do not align with the physiological response seen specifically in increased ICP. Understanding this pattern of vital sign changes is crucial for recognizing and managing potential neurological emergencies effectively.
