What is the hormone responsible for the maintenance of the endometrium during pregnancy and the maturation of mammary gland tissue?

  • A. Estrogen
  • B. Human chorionic gonadotropin (hCG)
  • C. Prolactin
  • D. Progesterone
Correct Answer: D

Rationale: The correct answer is D: Progesterone. Progesterone is essential for maintaining the endometrium during pregnancy by promoting its growth and preventing contractions. It also plays a crucial role in preparing the mammary glands for lactation. Estrogen (A) is important in the menstrual cycle but not specifically for maintaining the endometrium during pregnancy. Human chorionic gonadotropin (hCG) (B) is produced by the placenta and is primarily involved in supporting pregnancy and detecting pregnancy tests. Prolactin (C) is responsible for milk production but is not directly related to the maintenance of the endometrium or mammary gland tissue during pregnancy.

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.

A woman who is assessing fetal movements each day should notify her health care provider if:

  • A. More than six movements are felt during a 30- to 60-minute period.
  • B. Fetal movements are fewer than the minimum set by the provider.
  • C. The movement pattern remains about the same from day to day.
  • D. Fetal movements are more frequent during the evening than in the morning.
Correct Answer: B

Rationale: Decreased fetal movement may indicate a potential issue and requires further evaluation.

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.

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?

  • A. linea nigra
  • B. striae gravidarum
  • C. palmar erythema
  • D. pruritis
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.

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.
