FHR Monitoring V2 Practice Test

The choice indicating the action that is not appropriate for addressing a late deceleration pattern is correct because leaving the mother in the supine position can exacerbate the situation. Late decelerations indicate potential fetal distress, often related to uteroplacental insufficiency. The supine position can compress major blood vessels like the inferior vena cava, potentially reducing blood flow to the uterus and placenta, thereby worsening the fetal heart rate pattern.

In contrast, the other interventions listed—repositioning the mother, increasing IV fluids, and administering oxygen to the mother—are all aimed at improving uteroplacental circulation and enhancing fetal well-being. Repositioning the mother can relieve pressure on blood vessels, increasing blood flow. Increasing IV fluids helps to ensure adequate hydration and uteroplacental perfusion, while administering oxygen to the mother enhances oxygen delivery to the fetus. Each of these interventions serves to mitigate the risk associated with late decelerations, making them appropriate responses to the situation.
