Which finding is most indicative of fetal distress?

Which finding is most indicative of fetal distress?

• A. Late decelerations only
• B. Abnormal fetal heart rate with repetitive variable decelerations
• C. Increased fetal movement
• D. Normal fetal heart rate with reassuring tracing

Answer: (B)

The main idea is how fetal heart rate patterns reflect oxygen delivery to the fetus during labor. When the tracing is abnormal and decelerations occur repeatedly, this points to ongoing hypoxia from compromised placental or cord function. Recurrent variable decelerations, which are abrupt drops in heart rate that keep occurring, are most strongly associated with cord compression and persistent fetal distress. While late decelerations can signal uteroplacental insufficiency, they are less specific when they occur alone and without other concerning features. An increased fetal movement and a normal reassuring tracing are not signs of distress, but rather of stability.
