The client's last menstrual period (LMP) was December 17th, 2016 According to Nägele's Rule her expected cate of delivery (EDD) is:

A. September 17th, 2017: Calculating EDD by subtracting three months from the LMP and adding seven days would place the date earlier than the accurate estimate. This does not account correctly for the standard adjustment used in Nägele’s Rule. B. September 24th, 2017: Nägele’s Rule estimates the EDD by taking the first day of the last menstrual period, subtracting three months, and adding seven days. Starting from December 17th, 2016, subtracting three months gives September 17th, 2016, then adding seven days results in September 24th, 2017, providing the correct estimated delivery date. C. October 10th, 2016: This date is inconsistent with gestational length calculations. It falls too early relative to the standard 280-day pregnancy duration and does not follow Nägele’s Rule calculations. D. October 24th, 2017: This date overestimates gestation length by approximately one month. Adding seven days to the correct calculation places the EDD in late September rather than late October, making it inaccurate according to standard obstetric estimation.
