A football player is tackled and his knee bends inward. He feels a 'pop' and cannot bear weight. Which structure is most likely injured?
Answer: Medial collateral ligament (MCL) or ACL
A valgus (inward) force with a pop and inability to bear weight classically suggests MCL or ACL injury.
Which of the following is NOT a sign of a fracture?
Answer: Skin flushed and hot to touch without injury mechanism
Hot, flushed skin without trauma is not a fracture sign and may suggest infection or inflammation unrelated to fracture.
After applying a splint to an arm fracture, you notice the fingers become blue and cold. You should:
Answer: Loosen or remove the splint immediately
Blue, cold fingers after splinting indicate the splint is too tight and is cutting off circulation; it must be loosened immediately.
A victim is found with a bone protruding from a wound. The correct first aid is to:
Answer: Cover with a moist, sterile dressing without pressing on the bone
Protruding bone should be covered gently with a moist sterile dressing; never push it back or remove fragments.
A muscle cramp (charley horse) in the calf can be relieved by:
Answer: Gently stretching the calf by dorsiflexing the foot
Dorsiflexing the foot (pulling toes upward) stretches the calf muscle and helps relieve the spasm.
Which joint is most frequently dislocated in the body?
Answer: Shoulder (glenohumeral)
The shoulder is the most commonly dislocated joint because its shallow socket allows wide range of motion but provides less stability.
The 'E' in RICE stands for Elevation. The injured limb should be elevated:
Answer: Above the level of the heart
Elevating the injured limb above heart level uses gravity to reduce swelling by promoting fluid drainage.
