Answer to Question 1

ANS: B
The acidic pH, not the presence of autoantibodies, protects the vaginal mucosa. This protection is not associated with low levels of estrogen or with douching.

Answer to Question 2

ANS: D
Estradiol promotes breast development. Breast development during puberty is not associated with progesterone, prolactin, or oxytocin.
