What is the purpose of an amnioinfusion for a client diagnosed with oligohydramnios?

Amnioinfusion is a medical procedure where a sterile fluid is introduced into the amniotic cavity through the cervix during labor. This intervention is particularly beneficial for clients diagnosed with oligohydramnios, which is characterized by a lower than normal volume of amniotic fluid. The primary purpose of performing an amnioinfusion is to increase the volume of amniotic fluid, thereby improving fetal well-being and reducing the risks associated with oligohydramnios.

In this context, raising the amniotic fluid index to more than 15 cm is relevant because it helps cushion the umbilical cord and may alleviate pressure or compression that could lead to fetal distress. This increase in fluid can stabilize the fetal environment, reduce the chance of umbilical cord compression, and subsequently mitigate potential complications during labor.

While other options relate to aspects of fetal heart rate and management of fetal distress, they do not encapsulate the main goal of the procedure as accurately as the increase in amniotic fluid index does. Therefore, the purpose of an amnioinfusion is principally aimed at enhancing amniotic fluid levels, promoting a safer environment for the fetus during the birthing process.
