Glucose Management Practice Test

What is a fatal consequence of hypoglycemia?

Increased hair growth Brain doesn't have glucose for basic functions Enhanced memory Improved vision

Correct Answer:

Brain doesn't have glucose for basic functions

Explanation:

The brain relies almost entirely on glucose for its energy. When blood glucose drops, brain cells can’t generate enough energy to function, leading to neuroglycopenia where brain activity falters. This energy shortage quickly affects consciousness and vital brain functions, and if hypoglycemia isn’t corrected promptly, it can progress to seizures, coma, and potentially death. That’s why the statement about the brain not having glucose for basic functions describes the fatal consequence of hypoglycemia. The other options describe effects that don’t reflect the brain-energy crisis caused by low glucose.
