Question

A. Genu varum
B. Tibial torsion
C. Subluxation of the femur
D. Separation of the pubic bones

Answer 1

The cause of a waddling gait in a newborn with exstrophy of the bladder is separation of the pubic bones.

Step-by-step explanation:

The nurse would tell the mother that the cause of a waddling gait in a newborn with exstrophy of the bladder is separation of the pubic bones. Exstrophy of the bladder is a condition in which the bladder is outside the body. This can affect the normal alignment of the hips and pelvis, leading to an unusual walking pattern. The separation of the pubic bones can result in instability and a waddling gait when the child starts to walk.
