Answer to Question 1
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).
April 7 would be subtracting 2 months instead of 3 months then subtracting 3 days instead of adding 7 days.
March is the correct month, but instead of adding 7 days, 17 days were added.
April 17 is subtracting 2 months instead of 3.
Answer to Question 2
C
She has had four pregnancies, including the current one (gravida 4). She had two pregnancies that terminated after 20 weeks (para 2). The pregnancy that terminated at 8 weeks is classi-fied as an abortion.
Because she is currently pregnant, she is classified as a gravida 4.
Gravida 4 is correct, but she is para 2; the pregnancy that was terminated at 8 weeks is clas-sified as an abortion.
Since she is currently pregnant, she would be classified as a gravida 4, not 3; the para is cor-rect.
