  1. Tutorial endocrine pancreas Dr.MohammedSharique

  2. A patient in hyperkalemic renal failure is given an infusion of glucose and insulin. The actions of insulin include which of the following? • a. Converting glycogen to glucose • b. Stimulating gluconeogenesis • c. Increasing plasma amino acid concentration • d. Enhancing potassium entry into cells

  3. A 20-year-old diabetic male forgets to take his insulin prior to the start of the National Collegiate Athletic Association (NCAA) swimming championships. In which of his tissues Insulin-independent glucose uptake will occur? Why

  4. A 59-year-old man is brought to his physician’s office by his wife. She reports that he has been weak, nauseated, and urinates frequently. She has also noticed a fruity odor on her husband’s breath. • A urine sample is strongly positive for ketones and the finger-stick glucose is high(glucometer), leading to a presumptive bedside diagnosis of ---------------? DIABETIC KETOACIDOSIS As a result of insulin deficiency,which of the following will most likely occur? • a. Increased cellular uptake of glucose • c. Enhanced glucose uptake and use except by brain tissue • d. Decreased fatty acid release from adipose tissue • e. Increase ketogenesis

  5. A researcher studying type 2 Diabetes mellitus is inducing insulin resistance in normal mice. Which of the following types of inhibitors would be effective in producing this effect? • Tyrosine kinase

  6. A 25-year-old woman with type 1 diabetes comes to the emergency department complaining of thirst frequent urination, and weakness. She feels “lightheaded” when she stands.

  7. A 40 year old women wins Ras Al Khaimah half marathon in record time • Which of the following describes her hormone balance as she crosses the finish line? • Insulin high, glucagon high • Insulin high, glucagon low • Insulin low, glucagon low • Insulin low, glucagon high • Insulin equal to glucagon • Which of the following is decreased in concentration in her liver? • Fructose 6-phosphate • Phosphoenolpyruvatecarboxykinase • Fructose 2,6-bisphosphate • Glucose-6-phosphate • Phosphorylase
