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
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.
Correct Answer is B
Explanation
Choice A rationale:
Hypertension is not a typical symptom of abruptio placentae.
Choice B rationale:
Uterine tenderness is a common symptom of abruptio placentae.
Choice C rationale:
Fetal tachycardia is not a typical symptom of abruptio placentae.
Choice D rationale:
Leukorrhea is not associated with abruptio placentae.
The most likely finding the nurse should expect in a client experiencing abruptio placenta during labor is:
b. Uterine tenderness.
Here's why:
- Hypertension (a):While preeclampsia can increase the risk of abruptio placenta,it's not always present,and hypertension wouldn't be the immediate expected finding during the abruption event itself.
- Fetal tachycardia (c):This can occur in early stages of abruption to compensate for decreased oxygen supply,but as the abruption becomes more severe,fetal bradycardia is more likely due to oxygen deprivation.
- Leukorrhea (d):This is a white vaginal discharge and has no connection to abruptio placenta.
Uterine tenderness is a characteristic sign of abruptio placenta due to bleeding behind the placenta and irritation of the uterine muscle. This is often accompanied by:
- Vaginal bleeding (bright red or dark)
- Abdominal pain or cramping
- Sudden, ongoing uterine tightening or irritability
- Fetal distress (decreased fetal heart rate movements)
Therefore, option b is the most expected finding in this scenario.
Remember: Early recognition and prompt management of abruptio placenta are crucial for optimal outcomes for both mother and baby. If you suspect abruptio placenta, immediate medical attention is essential.
