The nurse is caring for a newborn who was delivered by cesarean birth. Which of the following is the most important reason this infant must be even more closely monitored than a newborn following a vaginal delivery?
 
  A) The newborn's oxygen lifeline is cut off when the umbilical cord is clamped, resulting in oxygen levels falling and carbon dioxide rising.
  B) The newborn will have more fluid in her lungs, making respiratory adaptation more challenging.
  C) Fetal lungs are uninflated and full of amniotic fluid that must be absorbed.
  D) Much of the fetal lung fluid is squeezed out as the fetus moves down the birth canal.
