The nurse is completing the family assessment on a patient at 10 weeks of gestation. What data are included in the family assessment? Select all that apply.

Correct Answer: A

Rationale: The correct answer is A: annual income. This data is crucial for assessing the family's financial resources and potential impact on the patient's health and well-being during pregnancy. Annual income can help identify possible financial stressors that may affect access to healthcare, nutrition, and overall prenatal care. B: Total number of cousins is not typically part of a family assessment during pregnancy and does not directly impact the patient's prenatal care. C: Number of people living in the household is important for understanding the household dynamics, but it may not be directly related to the patient's prenatal care needs. D: Identifying the person in the household who makes major decisions is important for understanding family dynamics, but it may not directly impact the patient's prenatal care.

Correct Answer: A

Rationale: The correct answer is A: First trimester. During the first trimester, gestational age can be accurately determined through ultrasound by measuring the crown-rump length of the fetus. This measurement is most accurate during this time as the fetus is small and growth is consistent. In the second and third trimesters, other factors such as fetal growth variations and positioning can affect the accuracy of gestational age determination. Therefore, the first trimester is the most accurate time for determining gestational age through ultrasound. Other choices are incorrect because the precision of ultrasound measurements decreases as pregnancy progresses, making the first trimester the optimal window for accurate gestational age assessment.

Correct Answer: C

Rationale: The correct answer is C: 10 weeks. CVS is typically performed between 10-12 weeks of gestation. At this time, there is enough fetal tissue for sampling without significant risk to the pregnancy. Performing CVS earlier (options A, B) may result in insufficient tissue for accurate testing, while performing it later (option D) may increase the risk of procedure-related complications. Option C provides the optimal balance between ensuring accurate results and minimizing potential risks to the pregnancy.

Correct Answer: B

Rationale: The correct answer is B: Information about the tests. The nurse's role in diagnostic testing is to educate the couple about the purpose, procedure, risks, and benefits of the tests. This empowers them to make informed decisions. Providing advice (A) may be beyond the nurse's scope. Reassurance about fetal safety (C) is important but not the primary role. While the nurse may assist with decision-making (D), the key focus should be on providing comprehensive information.

Correct Answer: D

Rationale: The correct answer is D: Determine fetal lung maturity. At 34 weeks of gestation, assessing fetal lung maturity is crucial to determine if the baby's lungs are developed enough for safe delivery. Amniocentesis can provide amniotic fluid for testing lung maturity. Choice A is incorrect as metabolic disorders are not typically assessed through amniocentesis. Choice B is incorrect as determining fetal sex is not the primary purpose of amniocentesis at this gestational age. Choice C is incorrect as identifying abnormal fetal cells is not the main goal of amniocentesis in this scenario.
