What is the term for when a baby lies sideways across the womb?

• A. Vertical position
• B. Transverse position
• C. Oblique position
• D. Breech position

Answer: (B)

When a baby lies sideways across the womb, it is referred to as the transverse position. This positioning indicates that the long axis of the baby's body is perpendicular to the long axis of the mother's body. It is significant because the transverse position presents challenges for delivery, as it is not an optimal presentation for vaginal birth.

In contrast, the vertical position generally indicates that the baby is either head-down or feet-down, while the oblique position refers to a diagonal lie of the fetus, where the baby is situated at an angle instead of in the transverse or vertical position. The breech position, on the other hand, is when the baby is positioned with the buttocks or feet down, further highlighting the distinction among these terms. Therefore, the transverse position is specifically associated with a sideways orientation of the baby in the womb.
