The effect of pregnancy on glucose metabolism is to:
 
  a. Enhance the action of insulin, creating a risk of hypoglycemia.
  b. Cause a woman to convert excess glucose to fat.
  c. Antagonize insulin, which causes serum glucose to rise.
  d. Stimulate the storage of excess glucose in the liver.

Question 2

The nurse recognizes that the primary effect of pregnancy on a woman with a preexisting heart disease is:

Answer to Question 1

ANS: C
Rising levels of maternal hormones during the second and third trimesters antagonize insulin. Therefore, insulin is less able to facilitate glucose metabolism. The result is a rise in serum glucose.

Answer to Question 2

ANS: D
The hemodynamic changes that occur during pregnancy (increased cardiac output, heart rate, blood, and stroke volume) increase the workload of the heart, placing the woman with a preexisting heart disease at risk for heart failure.
