You are a nurse caring for a 10-year-old child diagnosed with Duchenne Muscular Dystrophy (DMD). The child is experiencing difficulty with walking and frequent falls. What is the most appropriate nursing intervention to promote mobility and prevent falls for this patient?

Choice A rationale While wheelchairs offer mobility assistance, their continuous use can lead to muscle atrophy and further deconditioning in individuals with Duchenne Muscular Dystrophy. Promoting some level of independent movement, even with assistive devices, is crucial for maintaining existing muscle function and delaying disease progression. Over-reliance on a wheelchair might prematurely reduce weight-bearing activities vital for bone health and circulation. Choice B rationale Regular physical therapy, specifically focusing on strengthening exercises adapted for Duchenne Muscular Dystrophy, is paramount. This helps maintain existing muscle strength, slow the progression of muscle weakness, improve joint flexibility, and enhance overall functional mobility. Tailored exercises can also address compensatory movements and improve balance, thereby reducing the risk of falls and promoting ambulation for as long as possible. Choice C rationale While calcium and vitamin D are essential for bone health, their direct impact on improving muscle strength in the context of Duchenne Muscular Dystrophy is limited. DMD is a genetic disorder characterized by the absence of dystrophin, a protein vital for muscle fiber integrity. Supplementation may support bone density, but it does not address the underlying muscular dystrophy pathology or directly enhance muscle contractility. Choice D rationale Limiting physical activity excessively in Duchenne Muscular Dystrophy can lead to disuse atrophy, contractures, and a more rapid decline in mobility. A balanced approach is necessary, encouraging appropriate levels of activity to maintain muscle function without causing excessive fatigue or injury. Over-restriction can negatively impact both physical and psychological well-being, accelerating the progression of immobility.
