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.

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.
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.
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.
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.
Match each term with its description. Blastocyst
- A. None
- B. None
- C. Part of the blastocyst that will develop into the placenta.

Correct Answer: C
Rationale: Blastocyst contains structures forming the placenta.
