Which sign is commonly used to assess meningeal irritation in suspected meningitis?

• A. Nuchal rigidity
• B. Kernig sign
• C. Romberg sign
• D. Brudzinski sign

Answer: (D)

Meningeal irritation from meningitis often produces provocative signs when the meninges are stretched or manipulated. The Brudzinski sign is triggered by passively flexing the neck; in a patient with irritation, this causes an automatic flexion of the hips and knees. This reflexive, pain-free (or minimally painful) response directly demonstrates meningeal involvement, so it’s a classic and practical way to assess for meningitis. Nuchal rigidity also points to meningeal irritation but is a more general finding of neck stiffness rather than a dynamic test. Kernig sign involves pain and resistance when extending the knee with the hip flexed, another useful sign but sometimes harder to elicit or less sensitive. Romberg sign, by contrast, reflects problems with balance or proprioception and is not a sign of meningeal irritation. Thus, Brudzinski sign is the most specific, commonly used sign to assess meningeal irritation in suspected meningitis.
