A nurse is collecting data from an 8-month-old infant who has increased intracranial pressure (ICP). Which of the following manifestations should the nurse expect?

A. Insomnia: Infants with increased ICP are more likely to be lethargic than to have insomnia. B. Positive Babinski reflex: A positive Babinski reflex is normal in infants under 2 years and does not indicate ICP. C. Bulging fontanel: A bulging fontanel is a classic sign of increased ICP due to the accumulation of fluid or swelling inside the skull. D. Low-pitched cry: Infants with ICP typically have a high-pitched cry, not a low-pitched one.
