A nurse is assessing a five-month-old Infant. The nurse should recognize that which of the following manifestations is associated with a central nervous system (CNS) Infection?

A. Oliguria (decreased urine output) may be a sign of dehydration or kidney dysfunction but is not typically the primary symptom of a CNS infection. B. A negative Kernig's sign (no resistance to leg extension) is a reassuring sign and suggests that meningitis or other CNS infections are less likely. A positive sign would suggest possible meningitis. C. Bulging of the fontanel is a sign of increased intracranial pressure, which can occur in CNS infections such as meningitis. This is a critical finding that requires immediate attention. D. A negative Brudzinski sign means there is no neck stiffness or pain when the neck is flexed, which is a good finding. A positive sign would suggest the presence of meningitis.
