Define "nuchal cord".

Nuchal cord refers to the condition where the umbilical cord is wrapped around the fetus's neck. This occurrence can happen during pregnancy or delivery and is significant because it can lead to potential complications, such as restricted blood flow and oxygen supply to the fetus. While many births with nuchal cords proceed without serious issues, it is important for healthcare providers to be aware of the presence of a nuchal cord, as it can necessitate closer monitoring or specific interventions during labor and delivery.

Understanding this term is crucial for anyone involved in obstetrics and pediatrics, as it helps in identifying potential risks associated with childbirth. The other options provided do not pertain to the umbilical cord's position relative to the fetus and thus do not accurately reflect the definition of a nuchal cord.
