Which assessments are included in the fetal biophysical profile (BPP)? (Select all that apply.)

Choice A reason: This statement is incorrect, as it is not the definition of polyhydramnios, but rather a possible cause of it. Polyhydramnios is a condition where the amniotic fluid volume exceeds 2,000 mL at term, or the amniotic fluid index (AFI) is greater than 25 cm. Polyhydramnios can occur in multiple pregnancies, as the fetuses produce more urine and fluid than a single fetus.

Choice B reason: This statement is incorrect, as it is not the definition of polyhydramnios, but rather a possible complication of it. Polyhydramnios can cause fetal anomalies, such as esophageal atresia, anencephaly, or neural tube defects, which impair the swallowing or absorption of the amniotic fluid. Polyhydramnios can also cause fetal growth restriction or distress, as the excess fluid can compress the umbilical cord or the placenta, and reduce the blood flow and oxygen delivery to the fetus.

Choice C reason: This statement is correct, as it is the definition of polyhydramnios, which is a condition where the amniotic fluid volume exceeds 2,000 mL at term, or the amniotic fluid index (AFI) is greater than 25 cm. Polyhydramnios can be diagnosed by ultrasound, and it can cause maternal and fetal complications, such as preterm labor, premature rupture of membranes, placental abruption, or cord prolapse.

Choice D reason: This statement is incorrect, as it is not the definition of polyhydramnios, but rather a marker of fetal anomalies. Alpha-fetoprotein (AFP) is a protein that is produced by the fetus, and it can be measured in the maternal serum or the amniotic fluid. An elevated level of AFP in the amniotic fluid can indicate fetal anomalies, such as neural tube defects, abdominal wall defects, or renal anomalies, which can cause polyhydramnios.

Choice A reason: Primigravida in spontaneous labor with preterm twins is not at the greatest risk for early postpartum hemorrhage, as preterm births are associated with lower blood loss and smaller placentas. However, this client may have other complications, such as preterm labor, premature rupture of membranes, or fetal growth restriction.

Choice B reason: Primiparous woman (G 2, P 1-0-0-1) being prepared for an emergency cesarean birth for fetal distress is not at the greatest risk for early postpartum hemorrhage, as cesarean births are associated with higher blood loss and larger incisions. However, this client may have other complications, such as infection, wound dehiscence, or thromboembolism.

Choice C reason: Multiparous woman (G 3, P 2-0-0-2) with an 8-hour labor is at the greatest risk for early postpartum hemorrhage, as multiparity and rapid labor are both risk factors for uterine atony, which is the most common cause of early postpartum hemorrhage. Uterine atony is a condition where the uterus fails to contract and retract after delivery, and can cause excessive bleeding and hypovolemic shock.

Choice D reason: Woman with severe preeclampsia on magnesium sulfate whose labor is being induced is not at the greatest risk for early postpartum hemorrhage, as preeclampsia and magnesium sulfate are both risk factors for late postpartum hemorrhage, which occurs after 24 hours of delivery. However, this client may have other complications, such as eclampsia, HELLP syndrome, or placental abruption.
