Nuchal rigidity (stiff neck) is a red flag for which condition in children?

• A. Asthma
• B. Allergic rhinitis
• C. Gastroenteritis
• D. Meningitis

Answer: (D)

Nuchal rigidity, or stiff neck, signals irritation of the meninges surrounding the brain and spinal cord. In children, this is a warning sign that meningitis may be present, a serious infection that needs urgent evaluation and treatment. The neck stiffness occurs because the inflamed meninges make it painful to move the neck, reflecting a problem with the coverings of the brain rather than a simple muscular or respiratory issue.

The other conditions listed don’t involve the meninges. Asthma and allergic rhinitis are respiratory/allergic conditions presenting with breathing symptoms or nasal symptoms, not meningeal irritation. Gastroenteritis involves the gastrointestinal tract with symptoms like vomiting and diarrhea, not neck stiffness or other signs of meningitis.

Because meningitis can progress rapidly and can be life-threatening, a child with neck stiffness should be evaluated promptly by a clinician. This typically includes assessments and tests to confirm meningitis and start treatment quickly if suspected. Early antibiotics and appropriate investigations are crucial for the best outcome.
