  d. Cancer

Question 2

  Her parents state that she has been sick with the flu for a week. Which of the following state-ments best explains her acidotic state?
  a. Increased insulin levels promote protein breakdown and ketone formation.
  b. Her uncontrolled diabetes has led to renal failure.
  c. Low serum insulin promotes lipid storage and a corresponding release of ketones.
  d. Insulin deficiency promotes lipid metabo-lism and ketone formation.

Answer to Question 1

ANS: C
Cardiovascular disease, not renal disease, stroke, or cancer, is the ultimate cause of death in up to 68 of people with diabetes.

Answer to Question 2

ANS: D
With insulin deficiency, lipolysis is enhanced, and there is an increase in the amount of nonesteri-fied fatty acids delivered to the liver. The consequence is increased glyconeogenesis contributing to hyperglycemia and production of ketone bodies (acetoacetate, hydroxybutyrate, and acetone) by the mitochondria of the liver at a rate that exceeds peripheral use. Insulin levels are decreased. There is no evidence that the patient is in renal failure. Insulin is low, but the ketones are the re-sult of fatty acid breakdown due to lack of insulin, not because of lipid storage.
