A nurse is teaching a twelve-year-old boy with a casted left leg about cast care. The nurse determines that the child understands the teaching if the child states which of the following?
  1. “I need to avoid my cast getting wet.”
  2. “I can use a hair dryer on warm setting to relieve skin itching.”
  3. “I can use a ruler to scratch the itch underneath the cast.”
  4. “I should cover my casted leg with warm blankets.”
Explanation
Answer: A - The cast must remain dry to prevent it from breaking down and to reduce the risk of infection. A hair dryer on cool setting can relieve the itch. Nothing should ever be placed inside the cast. The air must circulate freely around the cast to keep it dry; therefore, the casted leg should not be covered with blankets.
