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.

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.
