During an assessment for signs of meningitis, what does a positive Kernig sign indicate?

• A. Pain upon flexion of the hip
• B. Pain with extension of the leg and knee
• C. Pain in the calf when dorsiflexing the foot
• D. Pain in the lumbar region when bending forward

Answer: (B)

A positive Kernig sign specifically indicates pain with extension of the leg and knee when the hip is flexed. This sign is assessed with the patient lying down. The examiner first flexes the patient's hip and knee to a 90-degree angle. If, upon extending the knee, the patient experiences pain, it suggests irritation of the meninges, which could indicate meningitis or other central nervous system conditions. The presence of a positive Kernig sign is significant because it reflects a possible inflammatory process affecting the meninges, which could lead to complications if not addressed. This sign, along with others such as Brudzinski's sign, helps clinicians in the clinical assessment for meningitis, allowing for a prompt diagnosis and treatment plan. Recognizing and understanding the implications of such signs are crucial in urgent medical settings, especially concerning conditions that could be life-threatening like meningitis.
