Final answer:
Amniotomy, artificial rupture of membranes (AROM), and external cephalic version (ECV) are obstetric interventions that can contribute to cord prolapse, an emergency condition requiring prompt action to prevent fetal distress.
Step-by-step explanation:
The obstetric interventions that contribute to cord prolapse include amniotomy, artificial rupture of membranes (AROM), and external cephalic version (ECV). These procedures can alter the normal positioning of the fetus or the umbilical cord, increasing the risk of the cord slipping into the cervix or vaginal canal ahead of the baby during delivery, which is known as cord prolapse. It is an obstetric emergency which requires immediate attention to prevent fetal distress.
