Answer to Question 1

ANS: B
Initial screening is completed with blood. AFP can be detected in amniotic fluid; however, that procedure is more costly and invasive. Procedures progress from least invasive to most invasive.

Answer to Question 2

ANS: B
Even though an L/S ratio of 2:1 is typically considered to be a normal finding to validate fetal lung maturity prior to 38 weeks' gestation, the result may not be accurate in determining fetal lung maturity if a client is diabetic.
