What is the intravenous dose of D10 for adult hypoglycemia?

• A. 100 ml
• B. 50 ml
• C. 10 ml
• D. 200 ml

Answer: (A)

Dextrose 10% solution provides 10 grams of glucose per 100 milliliters. In adults with hypoglycemia, the goal is to raise blood glucose promptly with a standard initial bolus of about 10 grams of glucose. Therefore, 100 milliliters of D10W delivers that 10 g dose and is commonly used as the starting IV bolus. If glucose remains low after this dose, clinicians may recheck and repeat or escalate to a higher-dose or higher-concentration dextrose per protocol. Smaller volumes would deliver too little glucose (50 mL = 5 g; 10 mL = 1 g), while a larger volume (200 mL = 20 g) is not the typical initial dose in many treatment protocols.
