A nurse is assessing an 11-month-old infant. Which of the following manifestations is associated with a CNS infection?

A. A bulging fontanel in an infant can indicate increased intracranial pressure, which is commonly associated with central nervous system (CNS) infections such as meningitis or encephalitis. It is a key early sign in infants because their cranial sutures have not yet fused. B. Jaundice is related to liver dysfunction or hemolysis and is not a typical manifestation of CNS infection. C. A negative Brudzinski sign indicates no neck stiffness; a positive Brudzinski sign is more suggestive of meningeal irritation in older children and adults. D. Oliguria, or decreased urine output, is related to renal or fluid balance issues and is not a specific indicator of CNS infection.
