Answer to Question 1

4

Rationale: Estrogen stimulates uterine development to provide an environment for the fetus and stimulates the breasts to prepare for lactation. Progesterone maintains the uterine lining for im-plantation and relaxes all smooth muscle. Human placental lactogen stimulates the metabolism of glucose and converts the glucose to fat; it is antagonistic to insulin. Human chorionic gonado-tropin prevents involution of the corpus luteum and maintains the production of progesterone until the placenta is formed.

Answer to Question 2

3

Rationale: The normal reference values for oral glucose tolerance tests are lower than 140 mg/dL at 120 minutes; lower than 200 mg/dL at 30, 60, and 90 minutes; and lower than 115 mg/dL in the fasting state. The other values are not part of the reference ranges.
