Conception and Fetal Development NCLEX Questions Questions
Question 1 of 5
The nurse is educating the pregnant person on the effects of the placenta hormones. What information does the nurse include in the teaching about relaxin? Select all that apply.
Correct Answer: C
Rationale: The correct answer is C because relaxin plays a role in the appearance of the linea nigra during pregnancy. Linea nigra is a dark line that runs from the belly button to the pubic bone caused by hormonal changes. Choices A, B, and D are incorrect. Relaxin primarily affects the cervix and pelvic ligaments, making them softer and more flexible to prepare for childbirth, but it does not help decrease peripheral vascular resistance or directly aid in skin stretching.
Question 2 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 3 of 5
The nurse is answering a phone call from a pregnant person. The pregnant person informs the nurse she has had several sharp pains in the right lower abdomen this week. What is the priority question the nurse should ask the pregnant person?
Correct Answer: A
Rationale: The correct answer is A: How many weeks pregnant are you? This is the priority question because sharp pains in the right lower abdomen could indicate an ectopic pregnancy or appendicitis, both of which are serious conditions requiring immediate medical attention. Knowing the gestational age will help the nurse determine the likelihood of these complications. Choice B: How much water are you drinking every day? is not the priority question as it is unlikely to be related to the sharp pains in the right lower abdomen. Choice C: When was your last bowel movement? is not the priority question as it is not directly related to the sharp pains in the right lower abdomen. Choice D: Are you lactose intolerant? is not the priority question as it is not likely to be the cause of sharp pains in the right lower abdomen for a pregnant person.
Question 4 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 5 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.
