A nurse is discussing hormones with a client who is pregnant. Which of the following statements should the nurse make?
"You may experience swelling due to decreasing estrogen levels throughout pregnancy."
"Human chorionic gonadotropin helps your cervix become soft as your body prepares for labor."
"Prolactin levels rise to prepare the breasts for lactation, which can cause in increase in breast size."
"Early in pregnancy, your body secretes a hormone called progesterone, which is what is tested to confirm pregnancy."
The Correct Answer is C
Estrogen levels actually rise during pregnancy.
B. "Human chorionic gonadotropin helps your cervix become soft as your body prepares for labor.": Relaxin is the hormone associated with softening of the cervix and pelvic ligaments.
C. "Prolactin levels rise to prepare the breasts for lactation, which can cause an increase in breast size.": Prolactin, secreted by the anterior pituitary, stimulates breast development and milk production.
D. "Early in pregnancy, your body secretes a hormone called progesterone, which is what is tested to confirm pregnancy.": Pregnancy tests detect hCG, not progesterone.
