In an obstetric scenario, which condition necessitates placing the provider's hand in the vagina to relieve fetal distress?

• A. Nuchal cord
• B. Prolapsed cord
• C. Shoulder dystocia
• D. Cephalad presentation

Answer: (B)

Relieving cord compression from a prolapsed umbilical cord is the action being tested. When the cord slips ahead of the presenting part into the birth canal, it can be pressed by the presenting part, leading to fetal hypoxia and distress. The most immediate and life-saving step is to insert a gloved hand into the vagina and gently lift the presenting part away from the cord, keeping the cord from being compressed. This manual elevation buys time for stabilization and delivery, usually by emergent cesarean section if vaginal delivery isn’t rapidly achievable. After doing this, position the patient to relieve pressure on the cord, administer oxygen, and call for urgent help to expedite delivery.

Nuchal cord involves the cord around the baby’s neck and is managed differently, often by reducing the cord over the head if possible or delivering with careful maneuvers. Shoulder dystocia centers on freeing the anterior shoulder with maneuvers rather than vaginally elevating a presenting part to relieve cord compression. Cephalad presentation refers to head-first delivery, which is the normal presentation and does not require this maneuver.
