Answer to Question 2

B
Keep the injured part immobilized and in alignment. Movement can cause further injury to strains, sprains, or fractures. Cold should be applied directly over the injury. Extreme temperatures can cause tissue damage. After 15 to 20 minutes (or as ordered by the physician), apply clean gloves, remove the compress or pad, and gently dry off any moisture.
