NCC Certified Electronic Fetal Monitoring (C-EFM) Practice Exam

What is the significance of recurrent late decelerations in EFM tracing?

1. Normal fetal response

2. Indicates possible fetal distress

3. Requires immediate delivery

4. Indicates fetal well-being

The correct answer is: Indicates possible fetal distress

Recurrent late decelerations in electronic fetal monitoring (EFM) tracings are significant because they suggest possible fetal distress. Late decelerations are characterized by a decrease in the fetal heart rate that begins after a contraction has started and returns to baseline only after the contraction has ended. This pattern typically indicates that there may be insufficient oxygen available to the fetus, often due to uteroplacental insufficiency, which can compromise fetal well-being. The presence of recurrent late decelerations prompts closer monitoring and further evaluation of both the mother and fetus, as it can indicate that the fetus is experiencing stress or compromised blood flow. While not all cases necessitate immediate delivery, their presence can lead to more urgent interventions depending on the severity and accompanying findings, such as the overall fetal heart rate pattern and maternal condition. Thus, identifying this pattern is crucial in managing labor and ensuring the safety of both the mother and child.
