Using Nagele's rule, what is the expected date of birth (EDB) for a client with a last menstrual period beginning April 22?

To determine the expected date of birth (EDB) using Nagele’s rule, one starts by identifying the first day of the last menstrual period (LMP) and then applies the formula, which is to add one year, subtract three months, and add seven days to that date.

In this case, the LMP is April 22. Following the steps of Nagele’s rule:

1. Start with the year of the LMP, which is the current year if the LMP has not yet occurred in the year of delivery.

2. Add one year to the LMP's year. For example, if the LMP is in 2023, then 2024 is the year you consider.

3. Subtract three months from the month of the LMP. April is the 4th month, so subtracting three months brings us to January.

4. Add seven days to the day of the LMP. Since the LMP is on the 22nd, adding seven results in the 29th.

Putting this all together, the EDB for a last menstrual period beginning on April 22 is January 29 of the following year. This calculation aligns perfectly with the first choice provided, making it
