Conception and Fetal Development NCLEX Questions Quizlet
Question 1 of 5
One of the assessments performed in the birth room is checking the umbilical cord for blood vessels. Which finding is considered to be within normal limits?
Correct Answer: A
Rationale: In a normal umbilical cord, there should be two vessels present - one artery and one vein. The most common finding is having one umbilical vein and two umbilical arteries, but it is also considered within normal limits to have one artery and one vein. This is important as an abnormal number of blood vessels in the umbilical cord can indicate potential issues like congenital abnormalities or genetic conditions.

Question 2 of 5
Some of the embryo’s intestines remain within the umbilical cord during the embryonic period because the
Correct Answer: C
Rationale: During early development of the fetus, the umbilical cord is relatively larger compared to later stages of pregnancy. This is because the umbilical cord plays a crucial role in providing necessary nutrients, oxygen, and removing waste products from the developing baby. As the pregnancy progresses, the blood vessels in the umbilical cord mature and shrink in diameter, leading to a decrease in its overall size compared to the early stages. The larger size of the umbilical cord in early pregnancy facilitates efficient nutrient exchange between the mother and the developing fetus, supporting the baby's growth and development.
Question 3 of 5
The nurse is conducting a staff in-service on multifetal pregnancy. Which statement regarding dizygotic twin development should the nurse include in the teaching session?
Correct Answer: C
Rationale: Dizygotic twins, also known as fraternal twins, result from the fertilization of two separate eggs by two sperm cells.
Therefore, they have different genetic makeups and can be the same sex or different sexes. This is in contrast to monozygotic twins (identical twins), who arise from a single fertilized egg that splits into two embryos, resulting in twins of the same sex and identical genetic makeup. It is important for the nurse to include this information in the staff in-service on multifetal pregnancy to ensure accuracy and understanding among the attendees.
