The nurse is teaching a pregnant client about the physiological effects and hormonal changes that occur during pregnancy. The client asks the nurse about the purpose of estrogen.
 
  The nurse bases the response on which of the following purposes of estrogen? 1. It maintains the uterine lining for implantation.
  2. It stimulates metabolism of glucose and converts the glucose to fat.
  3. It prevents the involution of the corpus luteum and maintains the production of progesterone until the placenta is formed.
  4. It stimulates uterine development to provide an environment for the fetus and stimulates the breasts to prepare for lactation.

Question 2

The client is undergoing an oral glucose tolerance test. The nurse interprets that the client's results are not compatible with diabetes mellitus if the glucose level is lower than which of the following cutoff values after 120 minutes (2 hours)?
 
  1. 80 mg/dL
  2. 110 mg/dL
  3. 140 mg/dL
  4. 160 mg/dL

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.
