This video reviews various aspects of hypernatremia, including the pathophysiology, etiologies, consequences, and treatment.

Hypernatremia is defined as a serum sodium level greater than 145 mEq/L.

It’s a common issue that dietitians face in the inpatient setting because it’s inextricably tied to derangements with fluid/electrolyte balance in the body.

Some interesting and helpful miscellaneous topics that appear in the video are arginine vasopressin disorders, osmotic diuresis, salt toxicity, calculating the free water deficit, and selecting the appropriate intravenous fluid to use.
