Final answer:
It's true that a dislocated hip is more likely in a footling breech birth due to the baby's legs extending towards the birth canal, which puts additional stress on the hip joints. The fetus is pushed out by uterine contractions, and the umbilical cord is usually cut after the baby starts breathing on its own. Displacement is equal regardless of the path taken in the described scenario.
Step-by-step explanation:
It is true that a dislocated hip is more likely to occur in a footling breech birth. During a footling breech delivery, one or both of the baby's feet come out first, which can increase the risk of hip dislocation among other complications. Unlike in a complete or frank breech, where the hips and knees are bent and the baby emerges buttocks first or with feet near the head respectively, the legs in a footling breech are extended towards the birth canal. This position can put additional stress on the baby's hip joints during delivery.
The fetus is typically pushed out of the uterus during birth by contractions of the uterine muscles.
The umbilical cord is cut after a newborn has started to breathe on its own to ensure that the baby is adequately oxygenated through their own lungs.
In the question of displacement, the statement is false. Displacement is a vector quantity that has both magnitude and direction, and is independent of the path taken. Therefore, walking 2 blocks east and 5 blocks north or 5 blocks north and then two blocks east results in the same displacement.
