When would Glucagon be used?

• A. For hyperglycemia
• B. In case of a severe hypoglycaemia attack
• C. To treat hypertension
• D. For nausea and vomiting

Answer: (B)

Glucagon is a hormone that plays a critical role in regulating blood glucose levels. It is specifically indicated for use in cases of severe hypoglycemia, which is a dangerously low level of blood sugar that can lead to serious complications, including loss of consciousness or seizures. When administered, glucagon stimulates the liver to release stored glucose into the bloodstream, effectively raising blood sugar levels and helping to counteract the effects of hypoglycemia. Given this context, its use is not appropriate for hyperglycemia, which involves high blood sugar levels, nor is it suitable for treating hypertension, as glucagon does not have a blood pressure-lowering effect. Additionally, while some medications may be used for nausea and vomiting, glucagon is not one of them; its primary function is to increase blood sugar levels in critical situations where a person cannot ingest sugar safely. Thus, the correct application of glucagon is specifically in scenarios of severe hypoglycemia, making it the appropriate choice in this situation.
