A child is diagnosed with Legg-Calvé-Perthes disease. The nurse knows that a key focus of nursing care for this child is:

Choice A rationale Legg-Calvé-Perthes disease involves avascular necrosis of the femoral head, requiring strict adherence to prescribed treatment, such as bracing or limited weight-bearing, to promote revascularization and prevent femoral head deformity. Non-compliance significantly increases the risk of long-term osteoarthritis and functional limitations. Choice B rationale Legg-Calvé-Perthes disease is not a terminal illness. While it can lead to chronic hip problems if not properly managed, it is a self-limiting condition where the bone eventually regenerates, albeit sometimes with residual deformity. Choice C rationale While pain management may be necessary, antibiotics are not a primary treatment for Legg-Calvé-Perthes disease as it is an aseptic necrosis, not an infection. The focus is on preserving the femoral head and restoring its blood supply. Choice D rationale Rehabilitation to regain mobility might be part of the long-term management after the acute phase or surgery, but the initial and key focus is on preventing further damage to the femoral head and ensuring proper healing, which often involves activity restriction.
