Assessment of High Risk Pregnancy NCLEX Questions Questions
Question 1 of 5
Which analysis of maternal serum is the best predictor of chromosomal abnormalities in the fetus?
Correct Answer: B
Rationale: The correct answer is B: Multiple-marker screening. This analysis measures levels of certain proteins and hormones in maternal serum to assess the risk of chromosomal abnormalities in the fetus. It is considered the best predictor because abnormal levels of these markers can indicate conditions like Down syndrome. Biophysical profile (A) assesses fetal well-being but does not directly predict chromosomal abnormalities. Lecithin-to-sphingomyelin ratio (C) is used to assess fetal lung maturity, not chromosomal abnormalities. Blood type and crossmatch (D) are important for identifying Rh incompatibility but do not predict chromosomal abnormalities.
Question 2 of 5
When is the earliest interval that chorionic villus sampling (CVS) can be performed during pregnancy?
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.
Question 3 of 5
The nurse's role in diagnostic testing is to provide which of the following?
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.
Question 4 of 5
What is the purpose of amniocentesis for a patient hospitalized at 34 weeks of gestation with pregnancy-induced hypertension?
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.
Question 5 of 5
What is the term for a nonstress test in which there are two or more fetal heart rate accelerations of 15 or more beats per minute (BPM) with fetal movement in a 20-minute period?
Correct Answer: C
Rationale: The correct answer is C: Reactive. In a nonstress test, a reactive result is considered normal and indicates a healthy fetus. This is because it shows two or more fetal heart rate accelerations of 15 or more BPM with fetal movement in a 20-minute period, which signifies a responsive and healthy fetal heart rate pattern. The other choices are incorrect because: A: Positive typically indicates a concerning result in medical contexts. B: Negative signifies an abnormal result in this context. D: Nonreactive suggests a lack of desired fetal heart rate accelerations with movement, which is not ideal.
