The umbilical cord is wrapped around the neck once, and there is no way to correct it; it cannot be rectified by changing position or through medication.

The umbilical cord being wrapped around the neck once can be due to the umbilical cord being relatively long, or the fetus having a large range of movement within the womb. During pregnancy, as the fetal movements change, it might wrap around twice or even three times, although it's also possible that there will be no wrapping of the umbilical cord around the neck by the end.

There is no need to panic if the umbilical cord is wrapped around the neck once. Pay attention to fetal movements and attend regular prenatal check-ups. If there is an increase or decrease in fetal movements, it is important to visit the hospital promptly to have an ultrasound, listen to the fetal heartbeat, and check for any signs of fetal hypoxia. If fetal hypoxia is present, oxygen therapy should be administered, and pregnancy termination may be necessary if required.
