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 began on November 15th.Which of the following is the appropriate response by the nurse?
July 12.
August 12.
August 22.
July 22.
The Correct Answer is D
Choice A rationale
Calculating the estimated date of delivery (EDD) involves adding 280 days (40 weeks) to the first day of the last menstrual period (LMP). Starting from November 15th, adding 280 days results in an EDD around August 22nd, not July 12th.
Choice B rationale
Using the same calculation method, adding 280 days to November 15th results in an EDD around August 22nd, not August 12th.
Choice C rationale
This choice is close but not accurate. Adding 280 days to November 15th results in an EDD around August 22nd.
Choice D rationale
This is the correct calculation. Adding 280 days to November 15th results in an EDD around August 22nd.

Correct Answer is C
Explanation
Choice A rationale
Allowing the older sibling to hear the baby’s heartbeat at a prenatal visit can help them feel involved and connected to the new baby. This can be a positive experience and does not require follow-up by the nurse.
Choice B rationale
Enrolling the older sibling in a sibling preparation class at the hospital is a good way to prepare them for the arrival of the new baby. These classes often provide valuable information and help older siblings understand what to expect.
Choice C rationale
Bringing the new baby home as a surprise can be problematic. It may cause the older sibling to feel excluded or unprepared for the new addition to the family. It is important to involve the older sibling in the process and prepare them for the changes that will come with the new baby.
Choice D rationale
Allowing the older sibling to pick out a gift for the baby and having a gift for them from the baby can help foster a positive relationship between the siblings. This approach can make the older sibling feel valued and included.
Correct Answer is C
Explanation
Choice A rationale
The placenta does not cushion the fetus from maternal movement. Instead, the amniotic fluid within the amniotic sac provides cushioning and protection to the fetus from external forces and maternal movements.
Choice B rationale
The placenta does not provide thermoregulation. Thermoregulation is primarily managed by the mother’s body. The placenta’s main functions are related to nutrient and gas exchange, hormone production, and waste removal.
Choice C rationale
The placenta is responsible for metabolic and gas exchange. It provides oxygen and nutrients to the fetus while removing waste products from the fetal blood. This exchange occurs through the placental barrier, which separates maternal and fetal blood.
Choice D rationale
The placenta does not provide a sterile environment. The amniotic sac and its fluid help maintain a sterile environment for the fetus. The placenta’s role is more focused on nutrient and gas exchange, hormone production, and waste removal.
