Using Nägele's rule, what is the estimated date of delivery for a client whose last menstrual period began on April 5 and ended on April 12?

• A. January 5
• B. January 12
• C. February 12
• D. December 12

Answer: (B)

To calculate the estimated date of delivery using Nägele's rule, you start with the date of the first day of the last menstrual period (LMP), which is April 5 in this case. The next steps involve adding one year, subtracting three months, and adding seven days to the LMP date. 1. Start with the LMP date: April 5. 2. Add one year: April 5, 2024. 3. Subtract three months: January 5, 2024. 4. Finally, add seven days: January 12, 2024. By following these steps, the estimated date of delivery calculated from the last menstrual period of April 5 results in January 12 of the following year. This method is commonly used in obstetrics to estimate a due date and is widely accepted for its effectiveness. Thus, the estimated date of delivery of January 12 is the correct answer.
