Which term best matches a solid device immobilizing a limb?

• A. Soft Splint
• B. Vacuum Splint
• C. Swathe
• D. Rigid Splint

Answer: (D)

Solid, nonflexible support is key for immobilizing a limb when there’s a fracture risk. A rigid splint provides that level of stabilization because it resists bending and movement, helping to keep the limb in proper alignment. It’s applied as a stiff, hard aid that extends beyond the injured segment to the joints above and below, which minimizes motion at the fracture site and protects soft tissues during transport until definitive care can be provided.

Soft splints are pliable and cushion the limb but don’t offer the same degree of rigid immobilization, so they’re less reliable for maintaining alignment. Vacuum splints can mold to the limb and become fairly firm, but their rigidity isn’t as consistently solid as a true rigid splint. A swathe is a wrap used to support or compress, which can aid immobilization but isn’t a rigid immobilizer itself.
