The nurse is monitoring a client with hypoglycemia. Glucagon provides which function?
a. It enhances the activity of insulin, restor-ing blood glucose levels to normal more quickly after a high-calorie meal.
b. It is a storage form of glucose and can be broken down for energy when blood glu-cose levels are low.
c. It converts excess glucose into glycogen, lowering blood glucose levels in times of excess.
d. It prevents hypoglycemia by promoting release of glucose from liver storage sites.
D
Glycogen is a counterregulatory hormone secreted by the alpha cells of the pancreas when blood glucose levels are low. The actions of glycogen that raise blood glucose levels include stimulating the liver to break down glycogen (glycogenolysis) and forming new glucose from protein breakdown (gluconeogenesis). The other statements are not accurate descriptions of the actions of glucagon.
