Conception and Fetal Development NCLEX Questions Questions
Question 1 of 5
The nurse is providing prenatal education to a pregnant person who is 10 weeks pregnant. The nurse informs the pregnant person the placenta supports continual gestation until term by producing what?
Correct Answer: B
Rationale: The correct answer is B: hormones. The placenta produces hormones such as progesterone and estrogen, which are crucial for maintaining the pregnancy and supporting fetal development. These hormones help regulate the menstrual cycle, support the growth of the fetus, and prepare the body for childbirth. Glucose (A) is essential for fetal growth but is not the primary function of the placenta. Oxygen (C) is carried through the placenta to the fetus but is not produced by the placenta itself. Waste (D) products are removed by the placenta, but they are not produced to support continual gestation.
Question 2 of 5
Identify the birthing place providing the most comprehensive labor, birth, and immediate postpartum and newborn care.
Correct Answer: A
Rationale: The correct answer is A: hospital with LDRP and NICU units. Hospitals with Labor-Delivery-Recovery-Postpartum (LDRP) and Neonatal Intensive Care Unit (NICU) provide the most comprehensive care for labor, birth, and immediate postpartum and newborn care. LDRP units allow women to stay in one room for the entire birthing process, ensuring continuity of care. The NICU is crucial for providing specialized care to newborns with complications. In-hospital birthing centers lack the full range of medical resources available in hospitals, free-standing birthing centers may not have immediate access to emergency care, and home births carry risks due to limited medical interventions available.
Question 3 of 5
Approximately 3 days after fertilization, what is the term for the developing zygote, which is a 16-cell mass?
Correct Answer: B
Rationale: The correct answer is B: Morula. At approximately 3 days post-fertilization, the zygote undergoes multiple cell divisions, forming a 16-cell mass known as a morula. This stage precedes the formation of a blastocyst, which occurs around day 5. The trophoblast refers to the outer layer of cells in the blastocyst responsible for implantation, while the embryoblast is the inner cell mass that gives rise to the embryo. Therefore, the morula stage accurately represents the 16-cell mass at this specific developmental timeline.
Question 4 of 5
Upon receiving report on a 36-week G1P0 patient, the nurse has been informed that the pregnancy is at high risk because the umbilical cords may become entangled. Which does the nurse understand about this pregnancy?
Correct Answer: B
Rationale: The correct answer is B: It is a monoamnionic, monochorionic twin gestation. In this type of pregnancy, twins share the same amniotic sac (monoamnionic) and placenta (monochorionic). This situation increases the risk of cord entanglement, leading to potential complications. The other choices are incorrect because they do not describe a pregnancy with the same level of risk for cord entanglement. Choice A, diamnionic, monochorionic, implies two amniotic sacs, reducing the risk of cord entanglement. Choice C, monoamnionic, dichorionic, describes a less risky scenario with two separate placentas. Choice D, diamnionic, dichorionic, indicates two separate sacs and placentas, also reducing the risk of cord entanglement.
Question 5 of 5
What is the hormone responsible for the maintenance of the endometrium during pregnancy and the maturation of mammary gland tissue?
Correct Answer: D
Rationale: The correct answer is D: Progesterone. Progesterone is essential for maintaining the endometrium during pregnancy by promoting its growth and preventing contractions. It also plays a crucial role in preparing the mammary glands for lactation. Estrogen (A) is important in the menstrual cycle but not specifically for maintaining the endometrium during pregnancy. Human chorionic gonadotropin (hCG) (B) is produced by the placenta and is primarily involved in supporting pregnancy and detecting pregnancy tests. Prolactin (C) is responsible for milk production but is not directly related to the maintenance of the endometrium or mammary gland tissue during pregnancy.
