Which method of medical induction involves rupturing the membranes artificially?

• A. Intercourse
• B. Balloon dilators
• C. Nipple stimulation
• D. Artificial rupture of membranes

Answer: (D)

The key idea is that some induction methods directly break the amniotic sac. Amniotomy, or artificial rupture of membranes, is the approach that intentionally opens the amniotic sac to release fluid. This can help labor progress more predictably and allows for internal fetal monitoring, and it’s often used to augment labor when contractions need a boost or when monitoring requires it, usually with oxytocin support. The other options don’t involve breaking the membranes. Intercourse can stimulate labor through prostaglandins and reflex oxytocin release but doesn’t rupture the membranes. Balloon dilators mechanically soften and open the cervix without breaking the membranes. Nipple stimulation raises oxytocin to strengthen contractions but again does not rupture the membranes.
