A 2-year-old child with developmental dysplasia of the hip has a spica cast applied. the mother asks the nurse how to keep the cast clean. how should the nurse respond?

Managed easily with lotion or oil. Some degree of discomfort is expected after cast application. Warm toes indicate intact circulation to the lower extremities. Peeling skin (desquamation) is the result of inadequate skin care. The child should receive a cool mist because it facilitates reduction of mucosal edema.
