Using Nägele's rule, if the client's last menstrual period started on March 7, 2018, what is the estimated date of delivery?

To determine the estimated date of delivery using Nägele's rule, the process involves adding one year to the first day of the last menstrual period, subtracting three months, and then adding seven days.

In this case, the last menstrual period (LMP) is March 7, 2018.

1. Start with the year: Add one year to 2018 to get 2019.

2. Subtract three months from March: March minus three months is December (the previous year).

3. Then, add seven days to the 7th: March 7 plus 7 days gives us March 14.

Therefore, the estimated date of delivery, based on this calculation, is December 14, 2018.

The correct answer in this context would indicate a delivery around that time in December 2018, which matches the date presented in option A, leading to a reasonable alignment with the calculations performed.
