Question

Quizplus · Accepted Answer

Nägele's Rule calculates the estimated date of delivery (EDD) by adding one year, subtracting three months, and adding seven days to the first day of the last normal menstrual period (LNMP). For an LNMP of April 20, the calculation would be: April 20 + 1 year = April 20 of the next year; April 20 - 3 months = January 20; January 20 + 7 days = January 27. Therefore, the EDD is January 27.
