                                                experiencing a severe hypoglycemic reaction who is semiconscious or
                                                unconscious and is unable to swallow. This client is at risk for aspiration.
                                                For this client, an injection of glucagon is administered subcutaneously
                                                or intramuscularly. In the hospital or emergency department, the client
                                                may be treated with an IV injection of 25 to 50 mL (12.5 to 25 g) of 50%
                                                dextrose in water.
