Based on a client's last menstrual period starting on February 15, what would be her expected date of delivery?

To determine the expected date of delivery (EDD), healthcare providers typically use Naegele's rule, which involves a straightforward calculation based on the first day of the last menstrual period (LMP). The general approach is to add one year, subtract three months, and add seven days to the date of the last menstrual period.

For this question, if the last menstrual period started on February 15, the calculation would proceed as follows:

1. Start with the year of the last menstrual period date. Let's assume it's 2023.

2. Add one year: 2023 + 1 = 2024.

3. Subtract three months from February: February minus three months lands you in November.

4. Add seven days to the 15th: 15 + 7 equals 22.

Putting all these steps together, the expected date of delivery is November 22, 2024.

This process demonstrates how Naegele's rule allows for estimating the due date accurately based on the menstrual cycle, which is a crucial aspect of obstetric calculations and prenatal care.
