Answer to Question 1

ANS: A
Fetal lung fluid is constantly produced and keeps the fetal lung inflated at a slight positive pres-sure with respect to amniotic fluid pressure and is important in promoting normal lung develop-ment.

Answer to Question 2

ANS: B
Quantification of these phospholipids (the L:S ratio and PG concentration) provides a predictive index of the lung maturity in the fetus before birth and the risks of developing respiratory dis-ease.
