Which fluid option is used in adult hyperglycemia management?

• A. Normal Saline: 1 L IV/IO
• B. Zofran: 4 mg IV/IO/PO
• C. D10: 5 ml/kg IV/IO
• D. Glucagon: 1 mg IM

Answer: (A)

In adult hyperglycemic emergencies, the starting move is to restore intravascular volume with an isotonic fluid, typically normal saline. This fluid choice helps improve circulating volume, perfusion to organs, and kidney function, which in turn supports glucose clearance and helps insulin therapy work more effectively. The other options aren’t used as the initial fluid for hyperglycemia: Zofran is just an antiemetic, not a fluid; D10 is dextrose-containing and reserved for hypoglycemia or to provide calories after insulin has begun, not for initial fluid resuscitation in hyperglycemia; glucagon is used to treat low blood sugar, not high. As treatment progresses and glucose drops toward a safer range (around 200 mg/dL), clinicians may switch to fluids that contain dextrose to continue insulin therapy without causing hypoglycemia.
