Positive Chvostek’s sign is a sign of:

Correct option is A

Ans. (a)
Sol. A positive Chvostek’s sign indicates hypocalcemia (low calcium levels in the blood). It is elicited by tapping the facial nerve in front of the ear, causing twitching of the facial muscles. This neuromuscular irritability results from low calcium, often seen in hypoparathyroidism or vitamin D deficiency.
Explanation of each option:
· (a) Hypocalcemia – Correct answer. Leads to increased neuromuscular excitability, causing Chvostek's and Trousseau’s signs.
· (b) Hypercalcemia – Usually causes muscle weakness, not twitching.
· (c) Hypokalemia – Affects muscle function and heart rhythm, not facial nerve excitability.
· (d) Hyperkalemia – Causes cardiac disturbances, not facial twitching.
