If a client's last menstrual period started on March 23, what is the estimated date of delivery using Naegele's rule?

To find the estimated date of delivery using Naegele's rule, you start by taking the first day of the last menstrual period and adding a year, subtracting three months, and then adding seven days.

In this case, the last menstrual period is March 23.

1. Start with the last menstrual period: March 23.

2. Add one year: This brings us to March 23 of the following year.

3. Subtract three months: Going back three months from March takes us to December of the previous year.

4. Add seven days: Adding seven days to December 23 results in December 30.

Therefore, the estimated date of delivery, using Naegele's rule, would be December 30. This method of calculation is widely used in obstetrics to estimate delivery dates by establishing a standardized approach to pregnancy duration, which is generally around 280 days or 40 weeks from the first day of the last menstrual period.
