Question

a splint is a device that maintains an injured part in place if the person must be moved. to be effective, a splint for a suspected broken bone should—
be made of stiff wood or metal parts throughout.
be applied to a limb that has been moved to its normal position.
include the joints above and below the injury site.

Explanation:

A splint for a suspected broken bone should include the joints above and below the injury site. This helps to immobilize the entire area properly. Making it of stiff wood or metal throughout is not necessary as modern splints can be made of other materials. Moving the limb to its normal position before splinting can cause more damage if there is a fracture.

Answer:

Include the joints above and below the injury site.
