What characterizes a complete breech presentation?

• A. Baby's feet are closest to the birth canal
• B. Baby's knees are bent with feet and bottom closest to the birth canal
• C. Baby's head is down with buttocks first
• D. Baby's foot is closest to the birth canal

Answer: (B)

A complete breech presentation is characterized by the fetus being positioned in such a way that the buttocks are oriented toward the birth canal, while the knees are flexed, and both feet are positioned near the bottom. In this position, the baby essentially sits in a cross-legged position, with the buttocks presenting first and the legs bent at the knees, making option B the correct description.

This positioning is distinct from other types of breech presentations, such as footling breech, where one or both feet are positioned towards the birth canal, or frank breech, where the legs are extended straight up with the feet close to the head. Understanding these variations is crucial for anticipating potential complications during delivery and choosing the appropriate management strategies.
