What describes an incomplete breech presentation?

• A. Both knees bent, feet and bottom closest
• B. One knee bent, foot and bottom closest
• C. Feet down, head up
• D. Head down, buttocks up

Answer: (B)

An incomplete breech presentation is characterized by one knee bent and the foot and bottom being the parts closest to the birth canal. This position means that while the baby's bottom is presenting, one leg is flexed with the foot positioned lower, which can complicate delivery compared to other breech presentations.

In breech presentations, the configuration of the body can change delivery dynamics. For example, complete breech involves both legs flexed with the feet and buttocks closest to the birth canal, while a footling breech, where one or both feet present, would not fit the definition of incomplete breech exactly as described. The correct description captures the essence of an incomplete breech, which is crucial for understanding delivery management for this presentation.
