A nurse in a prenatal clinic is caring for a client who asks what her estimated date of delivery will be if her last menstrual period was May 4, 2015. The nurse uses Naegele's Rule to calculate the correct EDD:
April 27, 2016
April 11, 2016
February 27, 2016
February 11, 2016
The Correct Answer is D
The correct answer is: April 11, 2016
Choice A: April 27, 2016
Reason: Using Naegele’s Rule, the estimated date of delivery (EDD) is calculated by adding one year, subtracting three months, and adding seven days to the first day of the last menstrual period (LMP). For an LMP of May 4, 2015:
- Add one year: May 4, 2016
- Subtract three months: February 4, 2016
- Add seven days: February 11, 2016
April 27, 2016, is incorrect because it does not follow the correct calculation steps.
Choice B: April 11, 2016
Reason: Following Naegele’s Rule:
- Add one year: May 4, 2016
- Subtract three months: February 4, 2016
- Add seven days: February 11, 2016
April 11, 2016, is the correct EDD as it accurately follows the calculation steps.
Choice C: February 27, 2016
Reason: This date is incorrect because it does not follow the correct calculation steps of Naegele’s Rule. The correct EDD should be in April, not February.
Choice D: February 11, 2016
Reason: This date is also incorrect. While it follows the initial steps of Naegele’s Rule, it does not account for the full calculation, which should result in an April date, not February.

Correct Answer is C
Explanation
Choice A: A weight gain of about 1 pound per week is a general guideline for women with normal BMI. However, for a client with a BMI of 26.5, the recommended weight gain during pregnancy may differ.
Choice B: Gaining 11 to 20 pounds may not be sufficient for a client with a BMI of 26.5, as the recommended weight gain is slightly higher for women with a higher prepregnancy BMI.
Choice C: For a client with a BMI of 26.5, the recommended weight gain during pregnancy is approximately 15 to 25 pounds. This range is specific to women with a BMI in the overweight category.
Choice D: Gaining 25 to 35 pounds is recommended for clients with a lower BMI range (normal BMI). For a client with a BMI of 26.5, this amount of weight gain may be excessive.
Correct Answer is D
Explanation
Choice A: Smoking is not directly associated with the development of type 1 diabetes mellitus in the baby.
Choice B: While smoking during pregnancy can have various effects on the baby's health, hearing loss is not one of the common complications.
Choice C: Although smoking during pregnancy is associated with an increased risk of congenital heart defects, intrauterine growth restriction is a more likely complication based on the client's smoking history.
Choice D: Smoking during pregnancy is associated with various adverse outcomes for both the mother and the baby. It can cause intrauterine growth restriction (IUGR), where the baby does not grow at the expected rate and has a lower birth weight. Smoking reduces blood flow to the placenta, which can affect the baby's growth and development.
