A nurse is calculating the estimated date of birth using Nägele's rule for a client who is pregnant and whose last menstrual cycle started June 21. Which of the following is the estimated date of delivery in the next year?
March 28.
March 21.
April 4.
March 14.
The Correct Answer is A
Nägele’s Rule is a standard way of calculating the due date for a pregnancy. The rule estimates the expected date of delivery (EDD) by adding one year, subtracting three months, and adding seven days to the first day of a woman’s last menstrual period (LMP).
So, if the last menstrual cycle started on June 21, here’s how you calculate:
- Subtract 3 months from June 21, which gives you March 21.
- Add 7 days to March 21, which gives you March 28.
- Add 1 year to the current year.
So, the estimated date of delivery in the next year would be March 28.

Correct Answer is C
Explanation
Choice A rationale:
Turning the newborn every 4 hours is not necessary during phototherapy. The aim of phototherapy is to expose the newborn’s skin to as much light as possible.
Choice B rationale:
Applying hydrating lotion to the newborn’s skin prior to treatment is not recommended. The aim of phototherapy is to expose the newborn’s skin to as much light as possible.
Choice C rationale:
Eye covers should be used to protect the newborn’s eyes from the light during phototherapy.
Choice D rationale:
Providing the newborn with 15 mL glucose water after each feeding is not necessary during phototherapy. The newborn may need to be fed more often to help get rid of the bilirubin in his or her bowel movements.
