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.

Genomic medicine is an emerging medical discipline that involves using genomic information about an individual as part of the individual’s clinical care. Which example does the nurse associate with genomic medicine?
- A. Screening of neonates for inherited, treatable genetic diseases
- B. Creating drugs specifically for the treatment of cancer
- C. Conducting trial studies to determine how drugs effect individuals
- D. Tracing and gaining knowledge about how genetic mutations occur
Correct Answer: A
Rationale: Rationale:
A is correct as genomic medicine involves using genetic information for clinical care, such as screening neonates for genetic diseases. This helps in early detection and treatment. B is incorrect as drug development is not the main focus of genomic medicine. C is incorrect as trial studies focus on drug effects, not genetic information. D is incorrect as tracing genetic mutations is related to genetics research, not clinical care in genomic medicine.
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.
A male patient is diagnosed with low sperm count as the cause of infertility. Which interventions will the nurse recommend to improve the patient’s sperm count? Select all that apply.
- A. Yoga or relaxation techniques
- B. Surgical repair of an inguinal hernia
- C. Switch to underwear made from cotton
- D. Avoidance of showers with hot water temperature
Correct Answer: A
Rationale: The correct answer is A: Yoga or relaxation techniques. Stress can negatively impact sperm count, so relaxation techniques like yoga can help reduce stress levels and improve sperm count. Surgical repair of an inguinal hernia (Choice B) is unrelated to sperm count. Switching to cotton underwear (Choice C) may help with ventilation, but it does not directly impact sperm count. Avoiding hot showers (Choice D) can prevent overheating of the testicles, but it is not as effective as stress reduction techniques in improving sperm count.
What are functions of the amniotic fluid? (Select one that doesn't apply.)
- A. Prevents congenital amputations and amniotic bands.
- B. Enables fetal musculoskeletal development.
- C. Protects the fetus from maternal infections.
- D. Maintains fetal hydration.
Correct Answer: C
Rationale: Amniotic fluid supports fetal development but does not protect against maternal infections.

- A. None
- B. None
- C. Part of the blastocyst that will develop into the placenta.
