Question: At a client’s first visit to the prenatal clinic, the nurse asks the client when she had her last menstrual period so the estimated date of birth (EDB) can be determined. The client responds, “January 21.” Using Nägele’s rule, what is the month and day of the client’s EDB?
1. October 21
2. October 28
3. November 21
4. November 28
Rationale: Nägele’s rule for determining the estimated date of birth (EDB) is to subtract 3 months from the first day of the last menstrual period and add 7 days and 1 year. According to Nägele’s rule, October 21 is too early and November 21 and 28 are too late.
