The nurse is working with a child who has a diagnosis of Duchenne muscular dystrophy. While assessing the motor development of a 6-year- old child, the nurse is most likely to find Gower's sign. This is evident when the child:

Demonstrates cog-wheeling in arm movements and in walking and shows a characteristic shuffling gait when walking

Walks flat footed with a duck-like walk, although the child will not walk unless someone insists and makes the child walk

Uses a series of maneuvers and walks the hands up the legs in order to rise from a sitting to a standing position

Grabs onto furniture or people in order to get from any position to a standing position
