What stage of labor begins with the birth of the infant and ends with the delivery of the placenta?

The stage of labor that begins with the birth of the infant and ends with the delivery of the placenta is the third stage. This stage is characterized by the physiological processes that occur following the birth of the baby, during which the placenta detaches from the uterine wall and is expelled from the body. This stage typically lasts a few minutes to half an hour, and it is crucial for ensuring that the uterus contracts properly to minimize bleeding and reduce the risk of complications.

The first stage of labor involves cervical dilation and the progression of labor to the point of delivery. The second stage follows, focusing on the expulsive phase where the infant is born. The fourth stage refers to the initial postpartum period, where the mother and infant are monitored closely after delivery to ensure their well-being. Understanding these stages helps in managing labor and delivery effectively, ensuring both mother and infant receive optimal care.
