What is the appropriate nursing action when late deceleration is observed on a fetal monitor tracing?

When late decelerations are observed on a fetal monitor tracing, placing the client in a lateral position is the appropriate nursing action. This position helps alleviate pressure on the umbilical cord and improves placental blood flow, which can enhance fetal oxygenation. Late decelerations are indicative of potential fetal distress, often related to uteroplacental insufficiency, and changing the position can effectively support fetal well-being.

Other interventions, such as administering oxygen or increasing IV fluids, are important in managing fetal distress, but the immediate action to improve blood flow and reduce pressure is to reposition the mother. Monitoring the client closely while in the lateral position allows for better assessment of the fetal heart rate pattern and maternal response. Positioning the client supine is counterproductive as it can exacerbate pressure on major blood vessels, potentially worsening the fetal condition.
