Dislocations occur when bones pop out of their regular socket in a joint.

• A. Sprains
• B. Dislocations
• C. Fractures
• D. Concussions

Answer: (B)

Dislocations happen when a bone is forced out of its normal position in the joint socket, so the ends of the bones no longer line up. That loss of alignment is what makes the joint look deformed, hurt intensely, and limit movement. This matches the idea being tested: the term describes a bone that has popped out of place at a joint. It’s different from a sprain, which is damage to ligaments around the joint but the bones remain in place; different from a fracture, which is a break in the bone itself; and different from a concussion, which is an injury to the brain from a blow. In a dislocation, the key feature is the misalignment of the joint surfaces. If you encounter this, keep the person still, immobilize the limb without trying to push the bone back in, apply ice for swelling, and seek urgent medical care to reduce and stabilize the joint.
