True or false: Early decelerations occur simultaneously with contractions and are considered a normal finding.

• A. True
• B. False
• C. True, but only if FHR does not return to baseline
• D. False under any circumstance

Answer: (A)

Early decelerations are a type of fetal heart rate pattern often observed during labor. They occur as a direct response to uterine contractions and are considered a normal physiological finding. The mechanism behind early decelerations is typically related to head compression as the fetus descends through the birth canal.

As the contraction begins, increased pressure on the fetal head leads to reflexive vagal stimulation, causing a temporary decrease in heart rate that mirrors the contraction. Importantly, these decelerations usually resolve as the contraction ends, with the fetal heart rate returning to its baseline level.

In contrast, late or variable decelerations are associated with potential fetal distress, and early decelerations do not indicate a compromised fetal well-being, which is why their occurrence is generally regarded as a reassuring sign during labor.
