A nurse is collecting data from a client at their first prenatal appointment. The client reports that the first day of their last menstrual period was September 17. Which of the following accurately represents the client's estimated date of delivery using Naegele's Rule?

Choice A rationale This choice is incorrect because Naegele's Rule involves adding seven days to the first day of the last menstrual period and then subtracting three months. Starting with September 17, adding seven days yields September 24. Subtracting three months from September 24 results in June 24, which is not the correct estimated delivery date according to the rule. Choice B rationale This choice is incorrect because applying Naegele's Rule requires a precise calculation. If the first day of the last menstrual period was September 17, adding seven days gives September 24. Subtracting three months from September 24 would result in June 24, not June 10, thus indicating an error in calculation for this option. Choice C rationale This choice is incorrect as it does not align with the application of Naegele's Rule. The rule specifies adding seven days to the LMP and subtracting three months. Starting from September 17, adding seven days brings it to September 24. Subtracting three months from September 24 mathematically leads to June 24, making June 20 an inaccurate calculation. Choice D rationale This choice is correct because Naegele's Rule is applied by adding seven days to the first day of the last menstrual period and then subtracting three months. With a last menstrual period of September 17, adding seven days results in September 24. Subtracting three months from September 24 accurately yields June 24 of the following year as the estimated date of delivery.
