During hypoglycemia in cardiac arrest, what is the D10 bolus volume?

• A. 100 ml
• B. 250 ml
• C. 500 ml
• D. 50 ml

Answer: (B)

The question tests how to dose dextrose for rapid correction of hypoglycemia in a cardiac arrest setting. You want to deliver about 25 grams of dextrose. A D10 solution has 10 grams per 100 milliliters, so to get 25 grams you need 250 milliliters. That makes 250 mL the appropriate bolus volume.

Other options would deliver different amounts of dextrose with the same concentrations: 100 mL provides 10 g, 50 mL provides 5 g, and 500 mL of D10 would provide 50 g. Since the target is 25 g of dextrose with D10, 250 mL is the correct choice.
