A nurse is collecting data from a client who has meningitis. When passively flexing the client's neck, the nurse notes an involuntary flexion of both legs. Which of the following conditions is the client displaying?

A. Kernig sign is elicited by flexing the client's hip and knee, then straightening the leg. Pain or resistance indicates meningeal irritation. B. Nuchal rigidity refers to stiffness of the neck, a classic sign of meningitis, but it does not involve reflexive leg movement. C. Brudzinski’s sign is positive when passive neck flexion causes involuntary flexion of the hips and knees. It is a classic indicator of meningeal irritation, such as in meningitis. D. Bradykinesia refers to slowness of movement, typically seen in Parkinson’s disease, not meningitis.
