What initial actions should a nurse take upon noticing repetitive late decelerations on a fetal heart monitor?

When a nurse observes repetitive late decelerations on a fetal heart monitor, it is indicative of uteroplacental insufficiency, which can compromise fetal oxygenation. The initial actions taken should prioritize improving blood flow and oxygen delivery to the fetus.

Repositioning the client is vital because changing their position can help relieve pressure on the umbilical cord or improve placental perfusion. Applying oxygen is another crucial step, as it enhances the amount of oxygen available to the fetus. Additionally, increasing IV fluids can help improve maternal hydration and circulation, which may support fetal well-being by promoting better placental blood flow.

These actions are foundational in a clinical response to late decelerations because they directly address the potential causes of decreased fetal heart rate patterns. Hence, implementing them at the onset of such findings helps to stabilize the situation and may prevent further fetal distress.
