Questions and Answers

What is the purpose of the fasting plasma glucose test?

  • To evaluate kidney function
  • To screen for diabetes mellitus and other disorders of glucose metabolism (correct)
  • To measure insulin resistance
  • To monitor cholesterol levels

    • How does glucagon affect plasma glucose levels in the fasting state?

  • It raises plasma glucose by accelerating glycogenolysis, stimulating gluconeogenesis, and inhibiting glycogen synthesis (correct)
  • It has no effect on plasma glucose levels
  • It decreases plasma glucose by promoting glycogen synthesis
  • It increases insulin secretion

    • What is the normal range for fasting serum glucose after an 8-12 hour fast?

  • 150-170mg/dl (8.3 – 9.4mmol/L)
  • 70-100mg/dl (3.9 – 5.6mmol/L) (correct)
  • 110-130mg/dl (6.1 – 7.2mmol/L)
  • 50-80mg/dl (2.8 – 4.4mmol/L)
