Trousseau's sign is elicited by which of the following conditions?
A
Hyponatremia
B
Hypocalcemia
C
Hyperkalemia
D
Hyperglycemia
Verified step by step guidance1
Understand the context: Trousseau's sign is a clinical sign that indicates neuromuscular irritability, often associated with certain electrolyte imbalances.
Identify the condition: Trousseau's sign is typically associated with hypocalcemia, which is a condition characterized by low levels of calcium in the blood.
Consider the physiological basis: Hypocalcemia increases the excitability of nerves and muscles, leading to spasms or contractions, which is what Trousseau's sign tests for.
Differentiate from other conditions: Hyponatremia (low sodium), hyperkalemia (high potassium), and hyperglycemia (high blood sugar) do not typically cause Trousseau's sign.
Conclude the association: Therefore, Trousseau's sign is specifically elicited by hypocalcemia, as it directly affects neuromuscular function.
