Which presentation describes the fetus entering the birth canal buttocks or feet first instead of the head?

• A. Cephalic presentation
• B. Breech presentation
• C. Transverse presentation
• D. Shoulder presentation

Answer: (B)

Fetal presentation describes which part of the fetus enters the birth canal first. When the buttocks or feet present first, that is breech presentation. This is in contrast to cephalic presentation, where the head is presenting first. Transverse presentation means the fetus lies sideways, so the shoulder would be the presenting part, not the head or buttocks. Shoulder presentation refers specifically to a transverse lie where the shoulder presents first. Breech can be classified as frank, complete, or footling, depending on how the legs and feet are positioned. Breech deliveries carry higher risk for complications and are often managed by cesarean delivery or with methods like external cephalic version if safe and feasible. Therefore, describing the fetus entering the birth canal buttocks or feet first aligns with breech presentation.
