EMT Signs and Symptoms Practice Test

The main idea is recognizing typical signs of a fracture versus clues that suggest a problem elsewhere. A fractured limb usually shows deformity from bone misalignment, intense localized pain, and crepitus if you feel or hear a crackling sensation as the bone ends rub together. Movement is generally painful and limited, and the limb may be swollen or tender to touch.

The finding of comfort and ease in moving the limb does not fit with a fracture, because genuine fractures almost always cause pain and guarding that limit movement. Deformity, pain, and crepitus all align with a fracture, whereas easy, painless movement suggests another issue or a less severe injury.
