Conception and Fetal Development NCLEX Questions Questions
Question 1 of 5
The nurse is providing education to a pregnant person at 10 weeks’ gestation who is experiencing nausea and vomiting. The nurse is aware the nausea and vomiting are due to which hormone produced by the placenta?
Correct Answer: B
Rationale: The correct answer is B: human chorionic gonadotropin (hCG). At 10 weeks' gestation, hCG is the hormone produced by the placenta responsible for nausea and vomiting, known as morning sickness. hCG levels peak around this time, coinciding with the onset of these symptoms. Relaxin (A), human placental lactogen (C), and luteinizing hormone (D) are not directly associated with causing nausea and vomiting in pregnancy.
Question 2 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 3 of 5
Identify the obstetric health care providers who attend births in private homes. Select all that apply.
Correct Answer: A
Rationale: The correct answer is A: OB/GYN. Obstetricians are trained to provide care during pregnancy, labor, and delivery in various settings, including private homes. Family practice physicians and maternal-fetal medicine specialists typically work in hospitals. Certified nurse-midwives can attend home births, but they are not the only obstetric providers who do so. OB/GYNs have the necessary expertise and skills to manage complications that may arise during home births, making them suitable providers for this setting.
Question 4 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 5 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.
