Final answer:
Using Naegele's rule, subtract three months from the LMP of April 1st, add one year and seven days to estimate a delivery date of January 8th of the following year.
Step-by-step explanation:
To estimate the delivery date using Naegele's rule given that the woman's last menstrual period (LMP) was on April 1st, you subtract three months, add one year, and then add seven days to the LMP. Starting with April 1st, you would subtract three months to get to January 1st, add one year to get to January 1st of the following year, and then add seven days to arrive at the estimated delivery date of January 8th of the following year. This is based on the standard assumption that conception occurred on day 14 of the menstrual cycle and that a full-term pregnancy lasts approximately 280 days from LMP.
To estimate the delivery date using Nagele's rule, we need to know the first day of the woman's last menstrual period (LMP). Using that information, we can add 280 days (approximately 40 weeks) to determine the estimated due date. In this case, if the woman's LMP was April 1st, we can add 280 days to that date. Therefore, the estimated delivery date would be January 7th of the following year.
