Hypoglycemic Emergency: Administering Dextrose

A nurse is caring for a patient who is experiencing a severe hypoglycemic episode. The patient is found to be unconscious and has a blood glucose level of less than 40 mg/dL. In this situation, the nurse recognizes the need for immediate intervention. To quickly raise the patient's blood glucose levels, the most appropriate intervention is to administer a concentrated solution of dextrose, commonly referred to as Dextrose 50% (D50).

To prepare this intervention, the nurse needs to fill in the blank with the correct volume of D50 to be administered based on standard protocols for treating hypoglycemia in unresponsive patients. If the standard dose for adults is ____ mL, how much D50 should the nurse prepare for administration?
