Question 5 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.
