What is the priority intervention for a nurse when assessing moderate fetal distress in a woman at 32 weeks' gestation?

Administering oxygen with a face mask at 7 to 10 L/min is the priority intervention in response to moderate fetal distress. This action helps increase the amount of oxygen available to the fetus, which is crucial when there are signs of fetal distress such as variable decelerations or other concerning fetal heart rate patterns. By enhancing the maternal oxygen supply, this intervention aims to improve fetal oxygenation and reduce potential complications related to hypoxia.

In the context of moderate fetal distress, it is critical to respond quickly to protect the well-being of the fetus. While initiating an IV line for fluids may be important for overall maternal hydration and circulation, immediate oxygen supplementation directly addresses the urgent need to improve fetal oxygen levels. Although calling the obstetrician is important for further evaluation and management, the fetal distress must be managed first to stabilize the situation. Performing a fetal heart rate monitor assessment is also relevant, yet the priority is to provide oxygen to correct any hypoxic conditions before further assessments or interventions.
