The mother of a child with cerebral palsy (CP) asks the nurse if her child's impaired movements will worsen as the child grows. Which response provides the best explanation?

A. Cerebral palsy is caused by brain injury or abnormal development, but the damage itself does not worsen over time. The severity of symptoms can vary as the child grows, but it is not progressive. B. While CP is a permanent disability, this response does not address the client’s concern about the progression of symptoms. C. The brain lesion in CP does not continue to develop in most cases, so this explanation would not provide accurate information. D. Severe motor dysfunction does not solely determine the child’s outcome, as therapy and early interventions can significantly improve functional abilities.
