A nurse is calculating the estimated date of delivery for a patient who reports that the first day of her last menstrual period was August 10. Using Nägele’s Rule, what is the patient’s estimated date of delivery?
May 17
May 3
May 20
May 13
The Correct Answer is A
Question: Estimated date of delivery using Nägele’s Rule.
Step 1: Add 7 days to the first day of the last menstrual period. August 10 + 7 days = August 17
Step 2: Subtract 3 months from the result. August 17 - 3 months = May 17
Step 3: Add 1 year to the result. May 17 + 1 year = May 17, 2025
Answer: May 17, 2025

Correct Answer is ["A","C","D"]
Explanation
Choice A rationale
Vacuum-assisted delivery can increase the risk of postpartum hemorrhage. This is because the use of vacuum can cause trauma to the birth canal and uterus, leading to increased bleeding.
Choice B rationale
A newborn weight of 2.948 kg (6 lb 8 oz) is within the normal range and does not increase the risk of postpartum hemorrhage.
Choice C rationale
Labor induction with oxytocin can increase the risk of postpartum hemorrhage. Oxytocin can cause the uterus to contract too strongly or too frequently, leading to uterine atony (a condition where the uterus fails to contract after delivery), which can result in heavy bleeding.
Choice D rationale
A history of uterine atony places the patient at risk for postpartum hemorrhage. Uterine atony is a condition in which the uterus fails to contract after the delivery of the baby and the placenta, leading to heavy bleeding.
Choice E rationale
A history of human papillomavirus (HPV) does not increase the risk of postpartum hemorrhage. HPV is a sexually transmitted infection that can cause genital warts and cervical cancer, but it does not affect the uterus’s ability to contract after delivery.
Correct Answer is D
Explanation
The correct answer is choice d. The procedure is not necessary to determine the sex of the fetus.
Choice A rationale:
Chorionic villus sampling (CVS) is another prenatal test that can determine the sex of the fetus, but it is typically performed between 10-13 weeks of gestation. However, it is not the standard response to a request for amniocentesis.
Choice B rationale:
Age is not a criterion for performing an amniocentesis. This procedure can be done for various medical reasons regardless of the mother’s age.
Choice C rationale:
Scheduling an amniocentesis for the same day is not appropriate, especially since the primary purpose of amniocentesis is to diagnose genetic disorders, not to determine the sex of the fetus.
Choice D rationale:
This is the correct response because non-invasive methods like ultrasound can determine the sex of the fetus without the need for an invasive procedure like amniocentesis, which carries risks.
