Final answer:
Using Nagele's Rule, the Estimated Date of Birth (EDB) for a woman whose last menstrual period started on October 17 is July 24.
Step-by-step explanation:
To calculate the Estimated Date of Birth (EDB) using Nagele's Rule, we take the first day of the woman's last menstrual period and subtract three months, then add seven days and one year.
Given that the first day of the last menstrual period was October 17, we subtract three months to reach July 17, and then add seven days to get July 24 as the EDB. So the answer to the question, 'If the first day of a woman's last menstrual period was Oct 17, what is her EDB using Nagele's Rule?' is b) July 24.
