In the event of an umbilical cord prolapse, the nurse should assist the client into which position?

In the case of umbilical cord prolapse, the knee-chest position is the most appropriate position for the client. This position helps to relieve pressure on the cord by encouraging fetal descent away from the pelvis, reducing compression of the umbilical cord. By keeping the mother's hips elevated and her upper body down, blood flow to the fetus can be increased, which is critical during a situation where the umbilical cord is at risk of becoming compressed.

This positioning also facilitates optimal conditions for potential emergency interventions to stabilize the fetal heart rate and maintain oxygenation until the situation is resolved, either through repositioning of the fetus or through delivery methods. In contrast, lying flat, sitting upright, or even a supine position does not provide the necessary relief from cord compression and can exacerbate the fetal distress caused by the prolapse. Thus, the knee-chest position serves a vital role in managing this obstetric emergency effectively.
