How do you utilize Nagele's rule to estimate a women's due date?
The nurse would assess the client's last menstrual period by subtracting 3 months and adding 7
days to the stated LMP date.
*Example: LMP = 11/21 (November is the 11th month), so 11-3 months = 8 (I.e., due date is
August). Now take the first day of the LMP and subtract 7 days (21 + 7 = 28th day). 8/28 is the
EDD.
