Final answer:
For a severely sprained ankle or wrist, immobilizing the joint, elevating it, and applying a cold compress is recommended as per the RICE technique. Additional treatments may include using a brace or cast, taking anti-inflammatory medication, and adhering to a physical therapy plan.
Step-by-step explanation:
The appropriate treatment for a person with a severely sprained ankle or wrist is to immobilize the joint, elevate it, and apply a cold compress. This follows the RICE technique which stands for Rest, Ice, Compression, and Elevation. Additionally, one may use a brace or cast to reduce the joint's mobility and, in cases of wrist tendinitis, icing, using non-steroidal anti-inflammatory medication, and complete rest are recommended. For muscle strains, adding protection and compression can help minimize damage and swelling. In physical therapy, heat packs, exercises at home, and icing may be part of the appropriate physical therapy plan to enhance healing and decrease inflammation. Orthopedists specializing in sports medicine may suggest treatments ranging from exercise to surgery for injuries like sprained ankles.
