Answer to Question 1

1
1. Correct. No risk screening system has resulted in lowering the preterm birth rate in the United States. About 25 of preterm births are intentional for health reasons, and about 25 happen because of spontaneous rupture of the membranes.

Answer to Question 2

3
1, 2, 4. Incorrect. Using Ngele's rule, calculate EDB by subtracting 3 months from the month of the LMP and adding 7 days plus 1 year to the day of the LMP. Therefore, LMP of February 14, 2007:

2 (Febru-ary) 14 (date) 2007
-3 months + 7 days + 1 year
= November = 21st of the month = 2007

3. Correct. Using Ngele's rule, this is the correct expected date of birth.
