What indicates the separation of the placenta during childbirth?

• A. Presence of contractions
• B. A change in the uterine contour
• C. Maternal blood pressure drop
• D. Visible umbilical cord lengthening

Answer: (B)

The separation of the placenta during childbirth is indicated by a change in the uterine contour. When the placenta begins to detach from the uterine wall, the shape of the uterus changes, often becoming more globular as the fundus rises and the uterus contracts. This change in contour is a key sign that the placenta is separating and is about to be delivered. While other signs and symptoms may accompany the delivery of the placenta, such as the presence of contractions and visible umbilical cord lengthening, they do not directly indicate the separation itself. Additionally, a sudden drop in maternal blood pressure can occur for various reasons and is not a reliable indicator of placental separation. Therefore, observing the change in the uterine contour is the most direct and reliable sign of placental separation during the third stage of labor.
