What characteristic manifestation does the nurse caring for a child with Duchenne's muscular dystrophy document?

A. Delayed fine-motor development is not typically an early or defining feature of Duchenne's muscular dystrophy (DMD); gross motor delays are more characteristic. B. In DMD, the calf muscles may appear enlarged (pseudohypertrophy) due to fat and connective tissue replacing muscle, not true atrophy in early stages. C. Holding onto furniture is more characteristic of toddlers with normal or delayed gross motor development, not specific to DMD. D. Frequent falls and clumsiness are hallmark early signs of DMD, reflecting progressive muscle weakness, especially in the pelvic and thigh muscles.
