Answer to Question 1

B
Feedback
A April 7 would be subtracting 2 months instead of 3 months and then subtracting
3 days instead of adding 7 days.
B To determine the EDD, the nurse uses the first day of the last menstrual period
(June 10), subtracts 3 months (March 10), and adds 7 days (March 17).
C March is the correct month, but instead of adding 7 days, 17 days were added.
D April 17 is subtracting 2 months instead of 3 months.

Answer to Question 2

A
Premature infants born before the gestational age of 36 weeks lack surfactant, so they are treated with surfactant replacement if they experience respiratory distress syndrome. Sodium bicarbonate is to treat the respiratory acidosis that accompanies respiratory distress syndrome. Betamethasone and Indomethacin are not used for respiratory distress syndrome.
