The nurse is caring for a neonate with congenital clubfoot. The child has a cast to correct the defect. Before discharge, what should the nurse tell the parents ？（）
A．"The cast will be removed in 6 weeks. "
B．"A new cast is needed every 1 to 2 weeks. "
C．"A short leg cast is applied when the baby is ready to walk. "
D．"The cast will be removed when the baby begins to crawl. "
参考答案：B
解析：
Because a neonate grows so quickly, the cast may need to be changed as often as every 1 to 2 weeks. A cast for congenital clubfoot isn't left on for 6 weeks because of the rapid rate of the infant's growth. By the time a baby is crawling or ready to walk, the final cast has long since been removed. After the cast is permanently removed, the baby may wear a Denis Browne splint until he is 1 year old.
