Acute hyponatremia become symptomatic at:: (A) <135 mEq, (B) <125 mEq, (C) <120 mEq, (D) <110 meq
Answer is B. Hyponatremia is commonly defined as a serum sodium <135 mmol/L (<135 mEq/L). In patient with hyponatremia that develops over hours, life-threatening seizures and cerebral edema may occur at values as high as 125 mmol/L. In contrast some patients with more chronic hyponatremia that has slowly developed over months to years may be asymptomatic even with serum levels <110 mmol
