What does an early deceleration in fetal heart rate indicate?

• A. Uterine hyperstimulation
• B. Cord compression
• C. Fetal head compression
• D. Placenta previa

Answer: (C)

An early deceleration in fetal heart rate is primarily associated with fetal head compression, which occurs during contractions when the fetal head presses down against the cervix. This pressure can trigger a reflex that results in a decrease in the fetal heart rate, typically mirroring the contraction pattern. Early decelerations are generally seen as a benign finding during labor, indicating that the fetal heart is responding appropriately to the physical stresses related to the birth process. In the context of the other options, uterine hyperstimulation usually leads to variable declerations rather than early ones, as it can cause changes in fetal oxygenation. Cord compression is usually associated with variable decelerations, which occur when the umbilical cord is compressed, affecting blood flow and oxygen delivery to the fetus but not specifically leading to early decelerations. Lastly, placenta previa involves complications related to the placenta's location and does not typically present with early decelerations in fetal heart rate.
