What would be administered for a patient with a blood glucose of 33 mg/dL who cannot tolerate oral intake?

For a patient presenting with a blood glucose level as low as 33 mg/dL who is unable to tolerate oral intake, the appropriate treatment is the administration of Dextrose 50% via intravenous push. This high concentration of dextrose is effective in rapidly elevating blood glucose levels, providing immediate energy to the body's cells.

When treating severe hypoglycemia, especially in a non-responsive patient, it is crucial to use a rapid-acting source of glucose, and Dextrose 50% is commonly used in clinical settings for this purpose. This concentration allows for quick restoration of normal blood glucose levels and minimizes the risk of complications associated with prolonged hypoglycemia.

Other potential treatments fall short for various reasons. Glucagon, while useful, is typically administered in scenarios where intravenous access is not feasible or when glucose must be raised in the home or field setting. Insulin, on the other hand, would be counterproductive in this context as it lowers blood glucose levels and is utilized for managing hyperglycemia instead of hypoglycemia. Dextrose 25% could be administered, but Dextrose 50% provides a more immediate and potent effect in emergency settings, making it the preferred choice when rapid intervention is necessary.
