A glucagon emergency kit is prescribed for a client with type 1 diabetes mellitus. When should the nurse instruct the client and family that glucagon needs to be administered?

A. When signs of severe hypoglycemia occur: Glucagon is used to rapidly increase blood glucose levels in cases of severe hypoglycemia when the person is unable to eat or drink. It is administered in emergency situations where the individual is unconscious or unable to consume oral glucose. B. Before meals to prevent hyperglycemia: Glucagon is not used to prevent hyperglycemia or as a routine preventive measure. It is specifically for emergency treatment of severe hypoglycemia. C. When unable to eat during sick days: While glucagon can be used if the person is unable to eat due to severe hypoglycemia, it is not typically used as a preventative measure for situations where the client is simply unable to eat. Regular monitoring and management of blood glucose levels are necessary during illness. D. At the onset of signs of diabetic ketoacidosis: Glucagon is not used to treat diabetic ketoacidosis (DKA). DKA is managed with insulin, fluids, and electrolytes, not glucagon.
