Final answer:
Nägele's rule is a method used to estimate a woman's expected delivery date based on the first day of her last normal menstrual period. The expected delivery date is calculated by adding 7 days to the first day of the last menstrual period, and then subtracting 3 months from the result. In this case, the woman's expected delivery date is May 12, 2014.
Step-by-step explanation:
Nägele's rule is a method used to estimate a woman's expected delivery date based on the first day of her last normal menstrual period. According to Nägele's rule, the expected delivery date is calculated by adding 7 days to the first day of the last menstrual period, and then subtracting 3 months from the result. In this case, the woman's last menstrual period began on August 5, 2013. Adding 7 days to August 5 gives us August 12, 2013. Subtracting 3 months from August 12 gives us May 12, 2013. Therefore, the woman's expected delivery date using Nägele's rule is May 12, 2014.
