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.
- A. makes the ligaments softer and more flexible
- B. helps decrease peripheral vascular resistance
- C. plays a role in the appearance of the linea nigra
- D. helps the skin stretch
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.

Identify the birthing place providing the most comprehensive labor, birth, and immediate postpartum and newborn care.
- A. hospital with LDRP and NICU units
- B. in-hospital birthing center
- C. free-standing birthing center
- D. home birth
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.
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?
- A. How many weeks pregnant are you?
- B. How much water are you drinking every day?
- C. When was your last bowel movement?
- D. Are you lactose intolerant?
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.
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?
- A. relaxin
- B. human chorionic gonadotropin
- C. human placental lactogen
- D. luteinizing hormone
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.
An expectant father asks the nurse, “Which part of the mature sperm contains the male chromosome?” What is the correct response by the nurse?
- A. X-bearing sperm
- B. The tail of the sperm
- C. The head of the sperm
- D. The middle portion of the sperm
Correct Answer: C
Rationale: The correct response is C: The head of the sperm. The head of the sperm contains the genetic material, including the male chromosome (Y chromosome). This is where the genetic information determining the sex of the offspring is located. The tail of the sperm is responsible for movement, not genetic material. X-bearing sperm would contain the female chromosome, not the male chromosome. The middle portion of the sperm does not specifically contain the genetic material related to determining the sex of the offspring.
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?
- A. glucose
- B. hormones
- C. oxygen
- D. waste
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.
