Which device is used to support an arm injury?

• A. Pelvic Binder
• B. Swathe
• C. Sling
• D. Vacuum Splint

Answer: (C)

Immobilizing an arm injury hinges on providing direct support to the arm so it can hang or rest without moving the shoulder and elbow. A sling accomplishes this by suspending the forearm from the shoulder, which unloads weight from the injured tissues and minimizes movement that could worsen pain or damage. It’s the simplest, most immediate way to immobilize an arm and give the patient relief.

A swathe can be used in conjunction with a sling to secure the arm to the chest or to stabilize the sling itself, but it is not the primary support for the arm. A vacuum splint offers rigid immobilization by molding around the limb, but it’s more time-consuming to apply and is typically reserved for more complex fractures. A pelvic binder is unrelated to arm injuries, as it’s used to stabilize the pelvis.

So, the sling is the device most specifically designed to support an arm injury by suspending and stabilizing the arm to reduce movement and pain.
