Passage / Scenario
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
C
Rationale
Using Nägele's Rule, the estimated date of delivery is calculated by adding 7 days to the first day of the last menstrual period and then counting forward 3 months. For choice C (17-May), adding 7 days to the first day of the last menstrual period gives 10-May. Counting forward 3 months from this date lands on 10-May, which makes 17-May the estimated date of delivery. Choice A (13-May) is incorrect as it does not follow the calculation correctly. Choice B (20-May) is incorrect as it does not align with the calculation based on Nägele's Rule. Choice D (2-May) is incorrect as it is an earlier date than the calculated estimated date of delivery.
