A woman arrives at the clinic for a pregnancy test. Her last menstrual period (LMP) was February 14, 2007. Her expected date of birth (EDB) would be:
1. September 17, 2007.
2. November 7, 2007.
3. November 21, 2007.
4. December 17, 2007.
3
1, 2, 4. Incorrect. Using Nägele'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 Nägele's rule, this is the correct expected date of birth.
