Answer to Question 1

ANS: A
After the birth of the infant and expulsion of the placenta, there is a rapid decrease in estrogen, progesterone, and human placental lactogen (hPL). These changes stimulate the anterior pituitary to produce prolactin, which stimulates milk production.

Answer to Question 2

ANS: B, C, E
When a newborn is not circumcised, instructions concerning penile hygiene should be provided to the parents. These include avoiding forceful retraction of the foreskin to prevent tearing, washing the penis with only water during infancy, and being aware that smegma is a normal shedding of skin cells.
