Answer to Question 1

ANS: B
Prolactin, secreted by the anterior pituitary, is a hormone that causes the breasts to produce milk. Estrogen decreases the effectiveness of prolactin and prevents mature breast milk from being produced. Progesterone decreases the effectiveness of prolactin and prevents mature breast milk from being produced. Human placental lactogen decreases the effectiveness of prolactin and prevents mature breast milk from being produced.

Answer to Question 2

ANS: C
The newborn needs 60 to 100 mL/kg of fluids daily for the first 3 to 5 days of life. 20 to 30 mL/kg and 40 to 60 mL/kg are too small an amount for the newborn. 120 to 150 mL/kg is too large an amount for the newborn.
