A client at 12 weeks' gestation asks about the purpose of nuchal translucency testing. What is the nurse's best response?

Correct Answer: C

Rationale: The correct answer is C because nuchal translucency testing is primarily used to screen for chromosomal abnormalities, such as Down syndrome, in the fetus. This test measures the thickness of the fluid-filled space at the back of the baby's neck. It is typically done between 11 and 14 weeks of pregnancy. This testing helps to assess the risk of genetic conditions in the fetus. Option A is incorrect because nuchal translucency testing does not screen for fetal anemia. Option B is incorrect because it does not detect neural tube defects. Option D is incorrect because it does not confirm gestational age.

Correct Answer: C

Rationale: Step 1: In the second stage of labor, the baby is descending into the birth canal for delivery. Step 2: Intense rectal pressure is a common sensation as the baby moves down. Step 3: This indicates progress in labor as the baby is descending. Step 4: Choice A is incorrect as breech position presents differently. Step 5: Choice B is incorrect as incomplete cervical dilation may not cause rectal pressure. Step 6: Choice D is incorrect as effective labor contractions are needed for descent.

Correct Answer: A

Rationale: The correct answer is A: Increased thirst and urination. In gestational diabetes, increased thirst and urination can indicate uncontrolled blood sugar levels, which can harm the fetus. This symptom suggests hyperglycemia and requires immediate intervention. B: Fasting blood glucose of 100 mg/dL is within the normal range for pregnancy and not concerning. C: Weight gain of 1 pound in a week can be normal in the third trimester and not specific to gestational diabetes. D: Proteinuria of +1 is more concerning for preeclampsia rather than gestational diabetes.

Correct Answer: C

Rationale: The correct answer is C because quickening, described as fluttering movements, is typically felt by pregnant individuals around 18-20 weeks of gestation. This indicates fetal movement and is an important milestone in pregnancy. Choices A and D are incorrect as fetal movements can be felt as early as 18-20 weeks. Choice B is incorrect as feeling strong, regular movements is not expected until later in the pregnancy.

Correct Answer: B

Rationale: The correct answer is B: Cervical dilation of 3 cm. This finding confirms preterm labor as it indicates cervical changes associated with labor progression. Regular uterine contractions every 10 minutes (choice A) may suggest labor but alone doesn't confirm preterm labor. Lower back pain and cramping (choice C) are common symptoms but not specific to preterm labor. A positive fetal fibronectin test (choice D) may indicate an increased risk of preterm labor but doesn't confirm the diagnosis definitively.
