The OB provider is concerned about placental perfusion and intrauterine growth restriction (IUGR) after noting minimal fetal growth over the past month.
What non-invasive antenatal test would the nurse anticipate the provider will order?
Magnetic Resonance Imaging (MRI).
Doppler flow studies.
Amniocentesis.
Chorionic villus sampling (CVS).
The Correct Answer is B
Choice A rationale
Magnetic Resonance Imaging (MRI) is a non-invasive imaging technique that provides detailed images of the fetus and placenta. However, it is not typically used as the first-line test for assessing placental perfusion and IUGR. Doppler flow studies are more specific for evaluating blood flow and detecting issues related to placental insufficiency.
Choice B rationale
Doppler flow studies are non-invasive tests that assess blood flow in the umbilical artery and other fetal vessels. These studies are particularly useful in evaluating placental perfusion and identifying intrauterine growth restriction (IUGR). Abnormal Doppler flow patterns can indicate compromised blood flow to the fetus, which is a concern in cases of minimal fetal growth.
Choice C rationale
Amniocentesis is an invasive procedure that involves extracting a sample of amniotic fluid for genetic testing and assessment of fetal lung maturity. It is not used for evaluating placental perfusion or IUGR7.
Choice D rationale
Chorionic villus sampling (CVS) is an invasive procedure used for early genetic testing by sampling placental tissue. It is not used for assessing placental perfusion or IUGR7.

Correct Answer is D
Explanation
Choice A rationale
Early decelerations are not caused by umbilical cord compression. Umbilical cord compression typically leads to variable decelerations, which have a different pattern and clinical significance.
Choice B rationale
Early decelerations are not caused by uteroplacental insufficiency. Uteroplacental insufficiency is associated with late decelerations, which occur after the peak of a contraction and indicate reduced blood flow to the fetus.
Choice C rationale
Early decelerations are not a result of the administration of medications. Medications can affect fetal heart rate patterns, but early decelerations are specifically related to fetal head compression.
Choice D rationale
Early decelerations are related to fetal head compression. They occur as the fetal head descends into the maternal pelvis and are generally considered benign, indicating normal labor progression.
Correct Answer is B
Explanation
Choice A rationale
Providing ice chips or mouth swabs can help keep the client comfortable and hydrated, but it is not the priority action when administering pain medication.
Choice B rationale
Assessing and documenting maternal vital signs and fetal heart rate after administering Fentanyl is crucial. This ensures that the medication is not causing any adverse effects on the mother or fetus and that both are stable.
Choice C rationale
Dimming the lights and providing a quiet atmosphere can help create a calming environment, but it is not the priority action when administering pain medication.
Choice D rationale
Assisting the patient with coping skills, including breathing techniques, is important for managing pain, but it is not the priority action when administering pain medication.
