Chvostek's and Trousseau's signs are indicative of which condition?

Chvostek's and Trousseau's signs are clinical indicators associated with low calcium levels in the blood, known as hypocalcemia.

Chvostek's sign is the twitching of facial muscles in response to tapping over the facial nerve, while Trousseau's sign is the induction of carpopedal spasm (hand or foot spasm) when a blood pressure cuff is inflated above the systolic pressure for a few minutes. Both signs are manifestations of neuromuscular excitability that occur due to the lower ionized calcium levels, which affect the stability of neuronal membranes, making them more prone to depolarization and activity.

In the context of the question, hypocalcemia can occur due to various reasons, including vitamin D deficiency, hypoparathyroidism, or chronic kidney disease. These conditions lead to decreased calcium levels that can cause the symptoms reflected by Chvostek's and Trousseau's signs.

The other options pertain to different electrolyte abnormalities that do not typically present with these specific signs associated with calcium deficiency. Hypercalcemia, for instance, is characterized by symptoms of lethargy, kidney stones, and abdominal pain rather than neuromuscular excitability. Hyperkalemia and hy
