A nurse is reinforcing teaching with a newly licensed nurse about embryonic nutrition.
Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?
Prior to the development of the placenta, the amnion provides nutrients.
The chorion supports development of the embryo.
The allantois will work to provide nutrients prior to the development of the placenta.
The yolk sac provides nutrients to the developing embryo.
The Correct Answer is D
Choice A rationale
The amnion is a membrane that encloses the amniotic fluid but does not provide nutrients to the embryo.
Choice B rationale
The chorion forms part of the placenta and contributes to nutrient and gas exchange once the placenta develops, but it does not provide nutrients before the placenta forms.
Choice C rationale
The allantois is involved in early fluid exchange and waste management but does not provide nutrients before the placenta forms.
Choice D rationale
The yolk sac provides nutrients to the developing embryo before the placenta is fully functional, supporting early embryonic development.

Correct Answer is B
Explanation
Choice A rationale
Placing a newborn on the parent's stomach and covering with a warm blanket helps to regulate body temperature through skin-to-skin contact, which is essential for newborns, especially shortly after birth.
Choice B rationale
Rectal temperature checks are not recommended for newborns due to the risk of rectal perforation. Newborn temperatures are typically monitored using axillary (underarm) methods.
Choice C rationale
Keeping a newborn’s head covered helps to prevent heat loss, as a significant amount of body heat can be lost through the head. This practice is crucial in maintaining the newborn's body temperature.
Choice D rationale
Newborns should be kept away from drafts, including fans and air conditioning vents, to prevent them from becoming too cold. Keeping the bassinet away from these can help maintain a stable temperature.
Correct Answer is B
Explanation
Choice A rationale
One parity indicates one delivery at a viable gestational age, which is not accurate for this client.
Choice B rationale
Two parity is correct as the client has delivered twins (considered one parity) at 36 weeks, which counts as one delivery at a viable gestational age.
Choice C rationale
Three parity is incorrect because the previous pregnancies did not result in three separate viable deliveries.
Choice D rationale
Four parity is incorrect as the client’s history includes one viable delivery (twins) and does not account for four separate viable births. .
