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

Rationale: A. A negative Brudzinski sign is expected in infants because this test is unreliable until after 2 years of age, so it does not indicate CNS infection. B. A bulging fontanel is a key sign of increased intracranial pressure, which can occur with CNS infections such as meningitis. C. Jaundice is related to liver dysfunction or hemolysis, not CNS infection. D. Oliguria is associated with dehydration or renal issues, not specifically with CNS infection.
