The labor and delivery nurse is assigned to four patients in early labor. Which electronic fetal monitoring finding would require immediate intervention?
1. Early decelerations with each contraction
2. Variable decelerations that recover to the baseline
3. Late decelerations with minimal variability
4. Accelerations
3
Rationale 1: Early decelerations are usually benign.
Rationale 2: Variable decelerations indicate cord compression, but those that recover to the baseline indicate that the fetus is tolerating the decelerations.
Rationale 3: Late decelerations are considered a nonreassuring fetal heart rate (FHR) pattern, and therefore require immediate intervention.
Rationale 4: Accelerations of the fetal heart rate indicate good oxygen reserve.
