A nurse is caring for a client who was admitted to the maternity unit at 38 weeks of gestation and who is experiencing polyhydramnios. The nurse should understand that this diagnosis means which of the following?

Choice A rationalePolyhydramnios is characterized by excessive amniotic fluid, exceeding 24 cm in amniotic fluid index. This can cause uterine distension and complicate labor and delivery.Choice B rationaleFetal congenital anomalies, growth restriction, or distress are possible complications of polyhydramnios, but they are not definitive diagnoses for the condition itself.Choice C rationaleCarrying more than one fetus is associated with increased amniotic fluid levels, but polyhydramnios specifically refers to the excess fluid, not the number of fetuses.Choice D rationaleElevated alpha-fetoprotein (AFP) levels can indicate neural tube defects or other fetal anomalies, but it is not a direct cause or indicator of polyhydramnios.
