The obstetrician is caring for a client with gestational hypertension. She 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?

Choice A rationaleMRI is not typically used for assessing placental perfusion or IUGR. It provides detailed imaging but is not the primary tool for evaluating fetal growth.Choice B rationaleDoppler Flow Studies are used to assess placental and fetal blood flow, making them crucial for evaluating placental perfusion and diagnosing IUGR in gestational hypertension.Choice C rationaleAmniocentesis is used for genetic testing and assessing fetal lung maturity, not for evaluating placental perfusion or diagnosing IUGR in gestational hypertension.Choice D rationaleChorionic Villus Sampling (CVS) is for early genetic testing and not suitable for assessing placental perfusion or IUGR, which requires evaluation of blood flow.
