A. While oral glucose is a good option for mild hypoglycemia, this patient is severely hypoglycemic and unable to swallow.
B. This is also appropriate for mild hypoglycemia, but the patient's condition warrants a more rapid- acting intervention.
C. D50 is a concentrated glucose solution that is administered intravenously for rapid correction of severe hypoglycemia. Given the patient's lethargic state and inability to follow commands, IV glucose is the most appropriate and immediate intervention.
D. While glucagon is an effective treatment for hypoglycemia, it is not the first-line treatment for a patient who is able to receive IV glucose. IV glucose is faster-acting and more reliable in this situation.
