A laboring patient at 6 cm dilation has a baseline fetal heart rate of 110 bpm with a variability of 16-18 bpm. These findings are most indicative of what?

• A. Fetal well-being
• B. Head compression
• C. Umbilical cord compression
• D. Uteroplacental insufficiency

Answer: (A)

Interpreting fetal heart rate in labor relies on baseline rate and beat-to-beat variability. A baseline around 110 bpm is within the normal range (about 110–160 bpm), and a variability of 16–18 bpm is moderate and reassuring. Together, these findings suggest the fetus is well-oxygenated with intact autonomic control. In labor, patterns like head compression cause early decelerations that mirror contractions; umbilical cord compression causes abrupt, variable decelerations; uteroplacental insufficiency leads to late decelerations after the contraction peak. Since no distress patterns are described and the baseline and variability are normal, this is most indicative of fetal well-being.
