Final answer:
For severe hypoglycemia, glucagon is administered to increase blood sugar levels. Insulin dosages may require adjustment if hypoglycemia occurs during insulin therapy.
Step-by-step explanation:
If a patient has hypoglycemia, which is a condition characterized by abnormally low blood sugar levels, certain medications can be administered to correct this imbalance. The primary treatment for severe hypoglycemia is the hormone glucagon, which is secreted by the alpha cells of the pancreas in response to low blood glucose levels. Glucagon stimulates the breakdown of glycogen to glucose, thereby increasing blood sugar levels. When a patient is unable to ingest sugar, emergency administration of glucagon via injection is the standard approach. Additionally, if a patient undergoing insulin therapy develops hypoglycemia, this may indicate the need to adjust their insulin dosage. It's important to monitor blood sugar levels regularly to manage the condition effectively.
