Which factor is NOT associated with increased risk of cord prolapse?

A normal fetal position is indeed associated with a reduced risk of cord prolapse. In a typical vertical or vertex presentation, the fetus is well-fitted into the pelvic cavity, which minimizes the likelihood of the umbilical cord slipping past the presenting part during labor. This positioning allows for optimal engagement of the fetus in the birth canal and helps to maintain the integrity of the umbilical cord's position.

In contrast, conditions such as polyhydramnios, breech presentation, and multiple gestation lead to increased risk factors for cord prolapse. Polyhydramnios can allow for excessive fetal movement and space, increasing the chances of cord displacement. Breech presentation creates a situation where the presenting part does not fit snugly into the pelvis, again increasing the risk of the cord prolapsing. Multiple gestations may involve positioning challenges and a higher likelihood of irregular presentations, further elevating the risk of cord prolapse. Hence, recognizing that a normal fetal position significantly diminishes the risk of cord prolapse helps clarify why it is the correct answer in this context.
