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 C
Explanation
Choice A rationale
Advising a pregnant friend to get the varicella vaccine postpartum is correct as it is a live vaccine not recommended during pregnancy due to potential risks to the fetus.
Choice B rationale
If a person had chickenpox, they likely have immunity, but it's still beneficial to assess for varicella zoster immunity to determine if vaccination is necessary.
Choice C rationale
Varicella vaccine requires two doses, and misunderstanding this indicates a need for further teaching to ensure complete immunization and protection.
Choice D rationale
Planning to get the second dose at the pharmacy 12 weeks postpartum is correct, showing understanding of the vaccination schedule and follow-up care.
Correct Answer is A
Explanation
Choice A rationale
Hypothyroidism during pregnancy is associated with increased risks of metabolic disorders, including lipid and glucose metabolism disorders, which can affect both the mother and fetus.
Choice B rationale
hCG levels do not typically plateau in the first trimester; they continue to rise and peak around the 10th week of pregnancy before starting to decline.
Choice C rationale
Thyroid replacement dosing usually needs adjustment during pregnancy to meet the increased thyroid hormone requirements due to physiological changes and fetal development needs.
Choice D rationale
Antenatal fetal surveillance is generally required in the third trimester for hypothyroid pregnant clients to monitor fetal well-being, not during the first trimester.
