Long Beach Lifeguard EMR Practice Exam

When distinguishing a fracture from a mild sprain in the field, look for signs that involve bone and alignment. Fractures often show deformity or abnormal alignment of the limb, possible crepitus with movement, noticeable swelling, and an inability to move or bear weight. Sprains, on the other hand, usually cause pain and swelling but the limb remains in normal alignment without bone crepitus. Keep in mind that non-displaced fractures may not look deformed, so assess tenderness along the bone, and always check distal circulation, sensation, and movement. If deformity, inability to move, or suspected fracture is present, immobilize with a rigid splint and transport for medical care.
