Anesthesia Pharmacology: Diabetes Management Practice Questions
Click on the correct answer.
Oral glucose administration induces a 3 to 4 times higher insulin response when compared to the same insulin dose but administered by the IV route of administration.
True
False
Incretins: Metabolic hormones that induce a reduction in blood glucose levels.
True
False
Incretin:
Released after eating
Inhibits insulin secretion from pancreatic
ß cells.
Both
Neither
GLP-1 (an incretin):
Enhances insulin secretion from pancreatic
ß cells of the islets of Langerhans.
Inhibits glucagon release from
α cells of the islets of Langerhans.
Less likely compared to sulfonylurea-type medications to cause a noteworthy insulin stimulatory effect
at normal glycemic levels.
Both
Neither
GLP-1: pancreatic and extra pancreatic physiological effects:
Decreases glucagon secretion
Preserves islet integrity
Delays gastric emptying

GLP-1 pharmacokinetics: GLP-1 half-life is about 1 to 2 hours.
True
False
GLP-1 pharmacokinetics:
Short half-life, one-to minutes, occurs as a result of rapid proteolysis by dipeptidyl peptidase 4 (DPP-4) another enzymes.
Rapid renal clearance.
Both
Neither
Since GLP-1's short half-life precludes clinical use, GLP-1 receptor agonists exhibiting longer half-lives have been synthesized and are clinically available.
