A patient brought to the ER is unconscious and is suspected of experiencing hypoglycemia. The hyperglycemic, glucagon is delivered IM to counteract this condition. What does the nurse understand to be the pharmacologic action of this drug?

A. Slows down gastric emptying to concentrate glucose in the bloodstream: Glucagon does not act on the gastrointestinal tract to delay gastric emptying. Slowing gastric emptying is a mechanism associated with certain antidiabetic drugs like GLP-1 agonists, not glucagon. B. Releases glycogen from the liver and muscles to be converted into glucose in the bloodstream: Glucagon stimulates glycogenolysis in the liver, breaking down stored glycogen into glucose, which is released into the bloodstream. This rapid increase in blood glucose makes it effective for treating severe hypoglycemia in unconscious patients. C. Converts fats into triglycerides for ready conversion into glucose in the bloodstream: Glucagon does not convert fats into triglycerides. While glucagon can promote lipolysis, its primary pharmacologic action in hypoglycemia is glycogenolysis, not fat metabolism. D. Releases glucose from the small intestine into the bloodstream: The small intestine absorbs dietary glucose but does not store it for rapid release. Glucagon’s effect is on liver glycogen stores, not intestinal glucose reserves.
