Question

If the first day of a woman's last normal menstrual period was May 28, what is the EDB using the Nagele rule?

Answer 1

The Estimated Date of Birth using Nagele's rule, based on the LMP of May 28, is March 7, 2024. This due date calculation is based on adding one year, subtracting three months, and adding seven days to the LMP.

Step-by-step explanation:

To calculate the Estimated Date of Birth (EDB) using Nagele's rule, you first identify the first day of the woman's last menstrual period (LMP). In this case, it is May 28. Nagele's rule states that to estimate the due date, you add one year, subtract three months, and add seven days to the LMP. Applying this to the given LMP:

• Add one year: May 28, 2024
• Subtract three months: February 28, 2024
• Add seven days: March 7, 2024

Therefore, the EDB would be March 7, 2024.
