A Nurse Plans to Teach a 4-Year-Old About What to Expect

A nurse plans to teach a 4-year-old about what to expect after his broken arm has been casted by:

A) bringing a doll and casting materials to the room, showing the casting materials and actually casting the doll's arm, and explaining the purpose of the cast.
B) telling the child that while he is asleep, the doctor will take off his arm and wrap it up.
C) breaking up the teaching sessions into two separate 5-minute sessions.
D) being treated as an adult because this approach helps the child to feel "grown up."
