Using Nägele's rule, what would be the estimated date of delivery (EDD) if a client’s last menstrual period began on April 5 and ended on April 12?

To calculate the estimated date of delivery (EDD) using Nägele's rule, the process involves taking the first day of the last menstrual period (LMP), adding one year, subtracting three months, and adding seven days.

In this case, the last menstrual period started on April 5. Here’s how you would apply Nägele's rule:

1. Determine the LMP: April 5.

2. Add one year: April 5 of the following year.

3. Subtract three months: This takes you back to January 5.

4. Add seven days: This results in January 12.

By following the steps accurately, you arrive at January 12 as the estimated date of delivery. This method is a widely accepted calculation in obstetrics for predicting the due date based on a 28-day menstrual cycle. It's important to note that this calculation assumes a regular cycle and may vary for individuals with irregular cycles.

The other choices provided do not align with the calculations based on Nägele's rule.
