The prenatal clinic nurse is responding to a patient who has had an assessment for fetal well-being. Which statement indicates that the patient understands the test result?
 
  1. The normal Doppler velocimetry wave result indicates my placenta is getting enough blood to the baby.
  2. The reactive nonstress test means that my baby is not growing because of a lack of oxygen.
  3. Because my contraction stress test was positive, we know that my baby will tolerate labor well.
  4. My biophysical profile score of 6 points indicates everything being normal and healthy for my baby.

Question 2

The nurse is preparing a patient in her second trimester for a three-dimensional ultrasound examination. Which statement indicates that teaching had been effective?
 
  1. If the ultrasound is normal, it means my baby has no abnormalities.
  2. The nuchal translucency measurement will diagnose Down syndrome.
  3. I might be able to see who the baby looks like with the ultrasound.
  4. Measuring the length of my cervix will determine if I will deliver early.

Answer to Question 1

Correct Answer: 1
Rationale 1: The Doppler velocimetry test looks at blood flow through the umbilical artery. A normal result indicates there is no vasospasm decreasing blood flow to the placenta; therefore, the baby is getting an adequate blood supply.
Rationale 2: The nonstress test utilizes external fetal monitoring to assess the fetal heart rate in relationship to fetal movement. When accelerations in the fetal heart rate are associated with fetal movement (a reactive result), the fetus is well oxygenated, and the placenta is functioning well.
Rationale 3: A contraction stress test creates mild contractions. The presence of decelerations is termed a positive result and indicates a lack of adequate placental functioning.
Rationale 4: The biophysical profile score should be 8 (with adequate amniotic fluid) or 10. A score of 6 is abnormal and indicates that further assessment is needed.

Answer to Question 2

Correct Answer: 3
Rationale 1: Not all fetal anomalies are detectable by ultrasound.
Rationale 2: Nuchal translucency measurements are screening, not diagnostic, for trisomies 13, 18, and 21.
Rationale 3: Ultrasounds provide a very clear photo-like image of the fetus, often providing parents the opportunity to identify a familial characteristic such as nose shape.
Rationale 4: Transvaginal ultrasound is used to measure the cervical length as a screening for risk of preterm labor. However, a normal-length cervix does not preclude preterm birth.
