If a diabetic patient received too much insulin the low blood sugar could be corrected by injecting what?

The correct answer is glucagon.

Glucagon is a hormone that raises blood sugar levels. It is produced by the pancreas, and it works by stimulating the liver to release glucose into the bloodstream. When a diabetic patient receives too much insulin, their blood sugar levels can drop too low. This is called hypoglycemia, and it can be corrected by injecting glucagon. Glucagon is a very effective way to raise blood sugar levels, and it is often used in emergency situations.
