The document describes the four stages of labor and delivery and associated nursing interventions: 1) First stage includes latent, active, and transition phases marked by cervical dilation and effacement. Nurses establish relationships, assess vital signs, provide comfort, and coach breathing. 2) Second stage is expulsion marked by urge to push. Nurses assist positions, coaching, and monitoring for delivery. 3) Third stage is placental delivery. Nurses observe for bleeding, examine placenta, provide postpartum care and newborn assessment. 4) Fourth stage is recovery. Nurses continue assessments, monitoring, and support for breastfeeding.
