17-year-old with type 1 diabetes
Question 1 of 5
17-year-old student with type 1 diabetes asks the nurse which hormone causes the blood glucose level to rise. When responding the nurse should explain in language that the client can understand that liver glycogenolysis is stimulated by a hormone secreted by the islets of Langerhans. Which hormone is this?
Correct Answer: C
Rationale: The correct answer is C: Glucagon. Glucagon is a hormone secreted by the alpha cells in the islets of Langerhans in the pancreas. It acts to stimulate the liver to break down glycogen into glucose, causing blood glucose levels to rise. This process is known as liver glycogenolysis. Insulin (choice
A) acts in the opposite way, lowering blood glucose levels by promoting glucose uptake by cells and inhibiting glycogenolysis. Epinephrine (choice
B) also stimulates glycogenolysis but is not secreted by the islets of Langerhans. Adrenocorticotropic hormone (ACTH) (choice
D) stimulates the adrenal glands to release cortisol, which can indirectly affect blood glucose levels but is not directly involved in liver glycogenolysis.
