A nurse is calculating the estimated date of delivery for a client who reports that the first day of her last menstrual period was August 10. Using Nägele’s Rule, which of the following is the client’s estimated date of delivery?

  • A. May 13
  • B. May 17
  • C. May 3
  • D. May 20
Correct Answer: B

Rationale: The correct answer is B: May 17. Nägele's Rule involves adding 7 days to the first day of the last menstrual period, subtracting 3 months, and then adding 1 year. In this case, starting from August 10, add 7 days to get August 17. Next, subtract 3 months to get May 17, and finally add 1 year to get the estimated date of delivery as May 17. Choice A (May 13) is incorrect as it does not follow the correct calculation steps. Choice C (May 3) is incorrect as it miscalculates the months. Choice D (May 20) is incorrect as it does not consider the subtraction of 3 months.
