Final answer:
Oligohydramnios can cause various fetal anomalies, such as renal agenesis, spina bifida, and hydrocephalus.
Step-by-step explanation:
Oligohydramnios, which refers to too little amniotic fluid, can lead to various fetal anomalies. One of the fetal anomalies that the nurse should expect in a client with oligohydramnios is renal agenesis, which is the absence of one or both kidneys. Another fetal anomaly that can arise due to oligohydramnios is spina bifida, a birth defect that occurs when the neural tube does not close completely, leading to the emergence of meninges and neural tissue through the vertebral column. Hydrocephalus, a condition characterized by the buildup of fluid in the brain, can also be a fetal anomaly associated with oligohydramnios.
