Identify the obstetric health care providers who attend births in private homes. Select all that apply.
- A. OB/GYN
- B. family practice physician
- C. maternal-fetal medicine specialist
- D. certified nurse-midwife
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.

A nurse is conducting prenatal education classes for a group of expectant parents. Which information should the nurse include in her discussion of the purpose of amniotic fluid? (Select all that apply.)
- A. Cushions the fetus
- B. Protects the skin of the fetus
- C. Provides nourishment for the fetus
- D. Allows for buoyancy for fetal movement
Correct Answer: A
Rationale: The correct answer is A: Cushions the fetus. Amniotic fluid acts as a cushion that protects the fetus from physical trauma and provides a stable environment for fetal growth. It helps prevent compression injuries and maintains a constant temperature. The other choices are incorrect because: B) Protects the skin of the fetus: While amniotic fluid does provide some protection, its main purpose is cushioning. C) Provides nourishment for the fetus: The placenta is responsible for providing nourishment to the fetus, not amniotic fluid. D) Allows for buoyancy for fetal movement: While amniotic fluid does allow for buoyancy, its primary function is to cushion the fetus.
Fewer fetal movements than expected suggest possible:
- A. Intrauterine fetal growth restriction.
- B. Inaccurate gestational age dating.
- C. Rapid intrauterine fetal maturation.
- D. Reduced placental perfusion with fetal hypoxia.
Correct Answer: D
Rationale: Reduced placental perfusion or fetal hypoxia can lead to fewer fetal movements.
Approximately 3 days after fertilization, what is the term for the developing zygote, which is a 16-cell mass?
- A. Trophoblast
- B. Morula
- C. Blastocyst
- D. Embryoblast
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.
The nurse works in a urologist’s office. A male patient is scheduled for routine fertility testing. For which test does the nurse refrain from making preparation?
- A. STI screening
- B. Hormonal levels
- C. Sexual functioning
- D. Ejaculate analysis
Correct Answer: C
Rationale: The correct answer is C: Sexual functioning. The nurse should refrain from making preparation for sexual functioning testing because this is not typically part of routine fertility testing. The focus of routine fertility testing for a male patient in a urologist's office would be on assessing sperm health and quality, which includes tests like semen analysis (choice D). STI screening (choice A) may be necessary to rule out any infections that could affect fertility, and hormonal levels (choice B) are important to assess the endocrine system's role in fertility. However, sexual functioning testing is not directly related to assessing fertility issues in this context.
A woman asks the nurse, 'What protects my baby's umbilical cord from being squashed while the baby's inside of me?' The nurse's best response is:
- A. Your baby's umbilical cord is surrounded by connective tissue called Wharton jelly, which prevents compression of the blood vessels and ensures continued nourishment of your baby.
- B. Your baby's umbilical floats around in blood anyway.
- C. You don't need to worry about things like that.
- D. The umbilical cord is a group of blood vessels that are very well protected by the placenta.
Correct Answer: A
Rationale: Wharton jelly surrounds the umbilical cord and prevents compression of the blood vessels.
