Conception and Fetal Development NCLEX Questions Questions
Question 1 of 5
Why might a provider recommend percutaneous umbilical blood sampling? Select all that apply.
Correct Answer: B
Rationale: Percutaneous umbilical blood sampling is recommended to detect Down syndrome accurately by analyzing fetal blood. This is because it directly tests the fetal blood for chromosomal abnormalities like Down syndrome, providing a definitive diagnosis. Other choices are incorrect because A does not specify the need for a direct blood test, C is too general, and D can be determined using other non-invasive methods like amniocentesis.
Question 2 of 5
The nurse receives a phone call from a pregnant person at 36 weeks’ gestation stating they have noticed some thin pink lines on the lower abdomen and wants to know if this is normal. The nurse recognizes the pregnant person is asking about what skin condition?
Correct Answer: B
Rationale: The correct answer is B: striae gravidarum. This skin condition consists of thin pink lines on the lower abdomen, commonly known as stretch marks, and is common during pregnancy due to rapid stretching of the skin. Linea nigra (A) is a dark line that appears vertically on the abdomen, palmar erythema (C) is redness on the palms, and pruritis (D) is itching which are not relevant to the description given.
Question 3 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 4 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 5 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.
