Question: 1 / 400

What is Chvostek's sign indicative of?

Hyperkalemia

Hypocalcemia

Chvostek's sign is indicative of hypocalcemia, which is a condition characterized by low levels of calcium in the blood. This sign is observed by a muscle twitching when the facial nerve is tapped, typically in front of the ear. The underlying mechanism involves increased neuromuscular excitability due to low calcium levels, which can lead to tetany and spasticity.

In clinical practice, recognizing Chvostek's sign can be crucial for diagnosing and managing patients at risk for hypocalcemia, which may arise from conditions such as parathyroid dysfunction, vitamin D deficiency, or certain medications. Understanding this sign helps emergency nurses promptly evaluate calcium levels and initiate appropriate treatments to prevent complications associated with hypocalcemia.
