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 C
Explanation
Choice A rationale
Keeping four side rails up is a safety measure to prevent falls, but it is not specific to the care of a client in active labor. It is a general safety precaution used for clients who are at risk of falling or have impaired mobility.
Choice B rationale
Inserting an indwelling urinary catheter is not a routine action for a client in active labor. Catheterization is typically reserved for specific medical indications, such as urinary retention or the need for accurate urine output measurement in certain high-risk situations.
Choice C rationale
Checking the cervix prior to administering medication is crucial in active labor. This ensures that the medication is appropriate for the stage of labor and helps avoid complications such as administering pain relief too early or too late, which could affect labor progression and fetal well-being.
Choice D rationale
Monitoring the fetal heart rate (FHR) every hour is important, but it may not be frequent enough in active labor. Continuous or more frequent monitoring is often required to promptly detect any signs of fetal distress and take appropriate actions.
Correct Answer is A
Explanation
Choice A rationale
Monitoring the fetal heart rate is the next appropriate action. The fetal heart rate provides crucial information about the fetus’s well-being and can help identify any potential issues that may need further intervention.
Choice B rationale
Monitoring uterine contractions is important, but in this scenario, the client’s vital signs are stable, and there is no indication of labor. Therefore, monitoring the fetal heart rate takes precedence.
Choice C rationale
Amniotic fluid levels are important to monitor, but they are typically assessed through ultrasound rather than immediate bedside monitoring. The fetal heart rate provides more immediate information about the fetus’s condition.
Choice D rationale
Cervical dilation is relevant during labor, but there is no indication that the client is in labor based on the provided vital signs. Monitoring the fetal heart rate is more pertinent in this situation.
