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 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 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 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 A
Explanation
Choice A rationale
This statement is incorrect because Stage 2 of labor does not involve the delivery of the placenta. Stage 2 starts with the complete dilation and effacement of the cervix and ends with the delivery of the fetus. The delivery of the placenta occurs in Stage 3 of labor.
Choice B rationale
This statement is correct. Stage 2 of labor begins with complete effacement and dilation of the cervix. This stage is characterized by the mother pushing and the eventual delivery of the baby.
Choice C rationale
This statement is also correct. Stage 2 starts when the cervix is fully dilated, allowing the mother to start pushing. This stage continues until the baby is born.
Choice D rationale
This statement is incorrect. Stage 2 ends with the delivery of the fetus, not the placenta. The delivery of the placenta is part of Stage 3 of labor.
Correct Answer is A
Explanation
Choice A rationale
The “Passenger” refers to the fetus and its position, size, and presentation. In this case, the fetus has an estimated weight of 9 lbs and is in the left occiput posterior (LOP) position. These factors can complicate labor by making it more difficult for the fetus to navigate through the birth canal, potentially leading to prolonged labor and increased risk of interventions.
Choice B rationale
The “Passage” refers to the birth canal, including the pelvis and soft tissues. While the passage is an important factor in labor, the primary concern in this scenario is the size and position of the fetus, which falls under the “Passenger” category.
Choice C rationale
The “Powers” refer to the strength and frequency of uterine contractions. Although the patient is having contractions every 3 minutes, the main concern here is the fetal size and position, which are more directly related to the "Passenger"4.
Choice D rationale
The “Psyche” refers to the psychological state of the mother, including her stress levels and emotional well-being. While important, the primary concern in this scenario is the physical factors related to the fetus, which are categorized under the "Passenger"4.
