Using Naegle’s rule, what would be the estimated date of delivery for a patient whose last menstrual period was July 6, 2007?

To estimate the date of delivery using Naegle’s rule, you start with the first day of the last menstrual period (LMP) and follow a specific formula: add one year, subtract three months, and add seven days to the date of the LMP.

In this case, the last menstrual period is July 6, 2007.

1. Add one year: July 6, 2007 becomes July 6, 2008.

2. Subtract three months: July 6, 2008 becomes April 6, 2008.

3. Add seven days: April 6, 2008 becomes April 13, 2008.

Thus, the estimated date of delivery for this patient would be April 13, 2008. This method is a standard way to calculate due dates and helps ensure that estimates are made consistently. The answer of April 13, 2008 aligns perfectly with the formula derived from Naegle's rule, making it the correct choice for this scenario.
