Discuss first aid treatment for sprains and strains.

First aid for sprains (injury to a ligament) and strains (injury to a muscle or tendon) follows the RICE method: 1. Rest: stop the activity and rest the injured part. 2. Ice: apply an ice pack wrapped in a cloth for 15 to 20 minutes, several times a day. 3. Compression: bandage the part firmly but not tightly to reduce swelling. 4. Elevation: raise the injured part above the level of the heart. 5. Consult a doctor if the pain or swelling persists.
