A patient who is pregnant asks the nurse for her due date. The patient's last menstrual period began on January 10th. What is the patient's due date based on Naegele's rule?

Naegele’s rule is the standard method for estimating a due date. The formula is: LMP + 1 year – 3 months + 7 days = Estimated Due Date (EDD) Step-by-step calculation: Start with the LMP: January 10th Add 1 year: January 10th → January 10th of the following year Subtract 3 months: January 10th → October 10th Add 7 days: October 10th + 7 days = October 17th Therefore, the estimated due date is October 17th.
