A client with type I diabetes mellitus has been prescribed a glucagon emergency kit for home use. When should the nurse instruct the client and family to administer glucagon?

Choice A rationaleAdministering glucagon prior to meals to prevent hyperglycemia is not a recommended use of a glucagon emergency kit. Glucagon is a hormone that raises blood glucose levels by causing the liver to release stored glucose into the bloodstream. It is typically used to treat severe hypoglycemia (low blood sugar), not to prevent hyperglycemia (high blood sugar).Choice B rationaleThe nurse should instruct the client and family to administer glucagon when symptoms of severe hypoglycemia are present. Severe hypoglycemia is a potentially life-threatening condition that can cause symptoms such as confusion, blurred vision, seizures, and loss of consciousness. In such cases, glucagon can be administered to quickly raise the blood glucose level.Choice C rationaleAdministering glucagon when the client is unable to eat during sick days is not a recommended use of a glucagon emergency kit. While it’s true that illness can affect blood glucose levels,glucagon is specifically used to treat severe hypoglycemia. Other strategies, such as adjusting insulin doses or consuming liquid or soft carbohydrates, are typically recommended when a person with diabetes is sick and unable to eat their usual meals.Choice D rationaleAdministering glucagon at the onset of symptoms of diabetic ketoacidosis is not a recommended use of a glucagon emergency kit. Diabetic ketoacidosis is a serious complication of diabetes that occurs when the body starts breaking down fat at a rate that is much too fast. The liver processes the fat into a fuel called ketones, which causes the blood to become acidic. Glucagon would not be effective in treating this condition.
