      That opposes the action of insulin.

    • B. 

      Secreted into the stomach to aid with starch digestion.

  • 6. 
    A male patient has had successive fasting plasma glucose readings of 115, 110, and 122 mg/dl. The healthcare provider will inform him that
    • A. 

      He appears to have impairment or borderline impairment of insulin-mediated glucose uptake by his cells.

    • B. 

      He is quite normal and can stop requesting this blood test.

    • C. 

      He needs more fasting plasma glucose because the range of these three values is too large to reach a conclusion.

    • D. 

      He has developed diabetes and needs to adopt lifestyle changes.

    • A. 

      Barium hydroxide is added to prevent blood clots.

    • B. 

      An enzymatic color reagent is added that digests and, thus, removes blood clots.

    • C. 

      Water is added to dissolve the glucose.

    • D. 

      Heparin is added to prevent blood clots.

    • B. 

      Optical density increases

    • C. 

      Optical density decreases

    • D. 

      Amount of color in the test tube decreases

  • 9.

    • C. 

      she has developed diabetes.

    • D. 

      She appears to have impairment or borderline impairment of insulin-mediated glucose uptake by her cells.

  • 10. 
    To maintain plasma glucose homeostasis
    • A. 

      Glucagon-mediated transport of glucose into cells acts as negative feedback when plasma glucose levels rise.

    • B. 

      Cells will become unresponsive to insulin if plasma glucose levels are chronically low.

    • C. 

      insulin-mediated transport of glucose into cells acts as negative feedback when plasma glucose levels rise.

    • D. 

      The pancreas will release insulin and glucagon together in order to offset a rise in plasma glucose.

  • 11.
