After several hours of labor, the electronic fetal monitor (EFM) shows repetitive variable decelerations in the fetal heart rate. The nurse would interpret the decelerations to be consistent with:
1. Breech presentation.
2. Uteroplacental insufficiency.
3. Compression of the fetal head.
4. Umbilical cord compression.
4
Rationale 1: Breech presentations by themselves do not cause decelerations.
Rationale 2: Uteroplacental insufficiency causes late decelerations.
Rationale 3: Early decelerations occur with fetal head compression.
Rationale 4: Variable decelerations occur when there is umbilical cord compression.
