What routine lab tests should a pregnant person have in the first trimester? Select all that apply.

  • A. complete blood count (CBC)
  • B. blood type and Rh factor
  • C. urinalysis
  • D. thyroid function tests
Correct Answer: D

Rationale: The correct answer is D: thyroid function tests. During pregnancy, thyroid function is crucial for the health of the mother and baby. Thyroid disorders can lead to complications. Testing thyroid function in the first trimester helps detect any abnormalities early.

A, B, and C are commonly performed tests in pregnancy, but they are not specific to the first trimester. A CBC helps assess overall health, blood type and Rh factor are important for identifying potential blood type incompatibilities, and urinalysis can indicate urinary tract infections or other issues. However, these tests are not unique to the first trimester and are typically done throughout pregnancy.

At which point in the pregnancy are alveoli formed and fetal breathing movements noted?

  • A. 12 weeks
  • B. 6 weeks
  • C. 20 weeks
  • D. 24 weeks
Correct Answer: D

Rationale: The correct answer is D (24 weeks) because alveoli formation and fetal breathing movements are typically observed during the late second trimester, around 24 weeks. At this stage, the lungs have developed sufficiently to support breathing outside the womb. Choices A (12 weeks), B (6 weeks), and C (20 weeks) are incorrect because alveoli formation and breathing movements do not occur as early as these time points in the pregnancy. Fetal breathing movements are a crucial sign of lung maturation and readiness for extrauterine life, which is why the correct answer is 24 weeks.

Which student statement requires further instruction?

  • A. It protects against cervical cancer and genital warts.
  • B. It is recommended for boys and girls, age 11-12.
  • C. It is an effective treatment for precancerous cervical changes.
  • D. It requires 2-3 doses.
Correct Answer: C

Rationale: The HPV vaccine is preventive, not a treatment for existing conditions.

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.

Where does conception most commonly occur?

  • A. None
  • B. In the ampulla of the fallopian tube.
  • C. None
  • D. None
Correct Answer: B

Rationale: Fertilization typically occurs in the ampulla.

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.
