Which device is used to immobilize an injured limb and prevent further injury?

• A. Splint
• B. Brace
• C. Radiograph
• D. EMG

Answer: (A)

Immobilizing an injured limb is achieved with a splint. A splint restricts movement of the affected area, protecting bones, joints, and soft tissues from further damage and making it safer to transport the person to care. It can be rigid or soft and is applied to immobilize the joint above and below the injury without forcing movement. After applying a splint, check that circulation and sensation remain intact distal to the injury. A brace can provide ongoing support, but in the immediate care of an acute injury, a splint is the device used to prevent further injury. Radiographs are imaging tests, and EMG measures muscle activity, neither of which immobilize.
