The nurse is teaching about congenital clubfoot in infants. The nurse evaluates the teaching as successful when the parent states that clubfoot is best treated:

Rationale: A. Treatment for congenital clubfoot should begin as soon as possible after diagnosis, often within the first few weeks of life. Early intervention improves the likelihood of successful correction with non-surgical methods like casting (Ponseti method). B. Waiting until 4–6 months delays treatment, which can lead to worsening deformity and more complex interventions. C. While treatment should be completed before walking begins, starting at 9–12 months is too late to begin initial correction. D. Treating after walking is established is not ideal and often requires more invasive procedures due to fixed deformity.
