Stages and Process of Labor

Overview

Labor is the process by which the fetus, placenta, and membranes are expelled from the uterus. It is divided into four distinct stages, each requiring specific nursing assessments and interventions. The nurse’s primary role is to ensure the safety of the mother and fetus while providing physical and emotional support.

Key nursing concepts

• The first stage of labor includes the latent, active, and transition phases.
• Fetal heart rate accelerations are a reassuring sign of fetal well-being.
• Late decelerations signify uteroplacental insufficiency and require immediate action.
• Station describes the position of the fetal presenting part relative to the ischial spines.
• Effacement is the thinning and shortening of the cervix during labor.
• The four P's of labor are Passenger, Passageway, Powers, and Psyche.

Important nursing considerations

• Monitor fetal heart rate during and after rupture of membranes to rule out cord prolapse.
• Assess maternal contraction frequency, duration, and intensity via palpation or monitor.
• Perform sterile vaginal exams sparingly to reduce the risk of infection.
• Evaluate the color and odor of amniotic fluid for signs of meconium or infection.
• Provide comfort measures like position changes, breathing techniques, and back massage.
• Monitor for maternal hypotension after the administration of epidural anesthesia.

Patient teaching

• Encourage the patient to use focal points and controlled breathing to manage pain.
• Explain that the urge to push (Ferguson reflex) typically occurs at 10 cm dilation.
• Instruct the patient to change positions frequently to help the baby rotate and descend.
