A nurse is assessing an infant following a motor vehicle crash. Which of the following findings should the nurse monitor to identify increased intracranial pressure?

A. Brisk pupillary reaction to light is a normal finding and does not indicate increased intracranial pressure (ICP). In fact, a sluggish or non-reactive pupil response is more indicative of increased ICP. B. Increased sleepiness or lethargy is an early sign of increased ICP in infants. The brain’s response to rising pressure can cause altered mental status, which includes drowsiness or difficulty waking. C. Tachycardia is not typically an early sign of increased ICP. As pressure increases, the heart rate can actually slow, and bradycardia (slower heart rate) is often seen in more advanced stages. D. Depressed fontanels are not indicative of increased ICP. In fact, in infants, increased ICP is more commonly associated with bulging fontanels, not depressed ones. Depressed fontanels could indicate dehydration or malnutrition.
