What should be administered if a person with hypoglycemia is unconscious?

1. Insulin

2. Glucagon

3. Oral glucose

4. Water

The correct answer is: Glucagon

In cases of hypoglycemia where a person is unconscious, administering glucagon is the most appropriate intervention. Glucagon is a hormone that stimulates the liver to release stored glucose into the bloodstream, thereby raising blood sugar levels. It is administered via injection in such emergencies and is crucial for individuals who cannot take oral glucose due to their unconscious state. Oral glucose is not feasible for someone who is unconscious because it cannot be safely ingested or absorbed. Insulin, which is used to lower blood glucose levels, would be detrimental in this situation as the individual is already experiencing low blood sugar. Water does not address the metabolic needs related to hypoglycemia and would not be effective in raising blood glucose levels. Using glucagon ensures a prompt response in increasing blood sugar levels and helps prevent the serious complications associated with prolonged hypoglycemia.
