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.
