A tube of glucose gel is administered to a hypoglycemic client. Which statement best describes this reversal?

• A. It liberates glucose from hepatic stores of glycogen.
• B. Insulin action is blocked as it competes for tissue sites.
• C. Glycogen is supplied to the brain as well as other vital organs.
• D. It provides a glucose substitute for rapid replacement of deficits.

Answer: (D)

The main idea is that glucose gel works by providing a rapid, readily absorbed source of glucose to reverse hypoglycemia. When the gel is placed in the mouth, glucose is absorbed through the mucous membranes and enters the bloodstream quickly, lifting blood glucose levels fast. This direct supply of glucose helps the brain and other tissues regain their energy almost immediately, without needing to rely on breaking down liver stores or waiting for digestion. The statement that best describes this reversal is that it provides a glucose substitute for rapid replacement of deficits. The other options describe mechanisms that aren’t how glucose gel works: it doesn’t trigger release of liver glycogen, it doesn’t block insulin action, and the brain uses glucose (not glycogen) as its energy source.
