Question 1 of 5
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?
Correct Answer: B
Rationale: The correct answer is B: May 17. Nägele's Rule calculates the estimated date of delivery by adding 7 days to the first day of the last menstrual period, then subtracting 3 months, and finally adding 1 year. In this case, August 10 + 7 days = August 17. Subtracting 3 months gives us May 17, which is the estimated date of delivery.
Choice A (May 13) is too early as it doesn't account for the full gestational period.
Choice C (May 3) is also too early, and choice D (May 20) is too late based on the calculation.
