What is a common sign of labor progression during the second stage?

During the second stage of labor, the process of delivering the baby is underway, and a common and notable change is rectal bulging. This occurs as the fetal head descends deeper into the pelvis and exerts pressure on the rectum. This distension is an important indicator that the baby is moving down the birth canal, creating the need for the mother to bear down during contractions. The presence of rectal bulging is a clear sign that the baby is in the process of being delivered, making it an essential observation for healthcare providers monitoring labor progression.

In contrast, the other options do not accurately represent signs of labor progression during the second stage. For example, while fetal heart rate (FHR) may be monitored throughout labor, a progressive increase in its location may not necessarily correlate with true labor progression, especially in the second stage. Additionally, a change in the positioning of the fetal head to one side is not a definitive indicator of labor progression, as fetal positioning can be influenced by various factors, including uterine contractions and the shape of the maternal pelvis. Lastly, a decrease in bloody show would not be associated with labor progression; rather, an increase in bloody show is typically expected as the cervix continues to efface and dilate
