Which sign is associated with hypocalcemia?

• A. Kernig sign
• B. Chvostek sign
• C. Babinski sign
• D. Romberg sign

Answer: (B)

Low calcium makes nerves and muscles more excitable, so small stimuli can trigger muscle contractions. The sign associated with hypocalcemia is seen when tapping the facial nerve just in front of the ear; this elicits twitching of the facial muscles on the same side. This response reflects the increased neuromuscular irritability that occurs with low calcium levels. In contrast, Kernig sign relates to meningeal irritation, Babinski sign to corticospinal tract problems, and Romberg sign to proprioceptive or vestibular issues, none of which are specific to hypocalcemia.
