Which sign indicates placental separation during labor?

The correct indication of placental separation during labor is the lengthening of the cord. This phenomenon occurs when the placenta detaches from the uterine wall, causing the umbilical cord to appear to lengthen as the placenta drops lower into the birth canal. This is often a tangible sign for the healthcare provider to assess that the expulsion of the placenta is imminent.

The lengthening of the cord is typically observed in practice and signals that the placenta is preparing to be delivered, which is critical for the management of the third stage of labor. Recognizing this sign helps ensure proper interventions are in place to facilitate the safe delivery of the placenta and to monitor for any complications, such as retained placenta.

The other signs mentioned, while they may be relevant in different contexts, do not specifically indicate placental separation. For example, fetal heart rate may change due to various factors during labor and does not directly reflect placental separation. Decreased uterine tone may occur due to other factors and does not serve as a reliable indicator of placental status. Moreover, reduced maternal blood pressure can result from various physiological changes during labor and does not have a direct correlation with placental separation. Understanding these distinctions is crucial for assessing the labor process effectively and ensuring maternal and
