What is the expected delivery date for a pregnant woman whose menstruation period was from April 10 to April 13?

• A. January 17
• B. January 20
• C. July 17
• D. July 20

Answer: (A)

To determine the expected delivery date, a common method used is Naegele's Rule, which calculates the due date based on the first day of the last menstrual period (LMP). In this case, the LMP is considered to start on April 10. According to Naegele's Rule, you would add one year to the year of the last menstrual period, subtract three months from the month, and then add seven days to the date. Starting from April 10: 1. Add one year: If the current year is X, it becomes year X + 1. 2. Subtract three months: April minus three months is January. 3. Add seven days: The 10th plus seven days brings you to January 17. This calculation results in an expected delivery date of January 17, which corresponds with the options provided. The reasoning behind this formula is grounded in a standard 40-week gestation period which typically begins from the first day of the menstrual period, making this method a reliable estimation for healthcare providers. Thus, January 17 is the correct expected delivery date based on the information given.
