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 A
Explanation
The correct answer is choice A. Single palmar creases.
Choice A rationale: Single palmar creases (also known as simian creases) can be associated with certain genetic conditions, such as Down syndrome. The presence of this finding in a newborn should prompt further investigation and reporting to the healthcare provider for additional assessment and possible genetic testing.
Choice B rationale: Rust-stained urine in a newborn is typically caused by uric acid crystals, which are common and not considered abnormal during the first few days of life. This condition usually resolves without intervention, and it does not require reporting to the provider unless it persists or is accompanied by other symptoms.
Choice C rationale: Transient circumoral cyanosis is a common finding in newborns, especially when crying or feeding. It usually resolves on its own and is not considered an alarming sign unless it persists or is associated with central cyanosis or other signs of respiratory distress.
Choice D rationale: Subconjunctival hemorrhage is a common finding in newborns, usually resulting from the pressure changes during delivery. It typically resolves on its own within a few weeks and does not require reporting to the provider unless there are signs of other underlying conditions.
Correct Answer is A
Explanation
Choice A rationale:
Poor feeding is a common manifestation in newborns of mothers who used methadone during pregnancy.
Choice B rationale:
A weak cry is not specifically associated with methadone use during pregnancy.
Choice C rationale:
An absent Moro reflex is not specifically associated with methadone use during pregnancy.
Choice D rationale:
A respiratory rate of 30/min is within the normal range for a newborn (30-60 breaths per minute) and does not indicate methadone exposure.
