First Aid Bone, Muscle, and Joint Injuries 4

Question 1

A football player is tackled and his knee bends inward. He feels a 'pop' and cannot bear weight. Which structure is most likely injured?

Accepted Answer

Medial collateral ligament (MCL) or ACL

Answer

A valgus (inward) force with a pop and inability to bear weight classically suggests MCL or ACL injury.

Question 2

Which of the following is NOT a sign of a fracture?

Accepted Answer

Skin flushed and hot to touch without injury mechanism

Answer

Hot, flushed skin without trauma is not a fracture sign and may suggest infection or inflammation unrelated to fracture.

Question 3

After applying a splint to an arm fracture, you notice the fingers become blue and cold. You should:

Accepted Answer

Loosen or remove the splint immediately

Answer

Blue, cold fingers after splinting indicate the splint is too tight and is cutting off circulation; it must be loosened immediately.

Question 4

A victim is found with a bone protruding from a wound. The correct first aid is to:

Accepted Answer

Cover with a moist, sterile dressing without pressing on the bone

Answer

Protruding bone should be covered gently with a moist sterile dressing; never push it back or remove fragments.

Question 5

A muscle cramp (charley horse) in the calf can be relieved by:

Accepted Answer

Gently stretching the calf by dorsiflexing the foot

Answer

Dorsiflexing the foot (pulling toes upward) stretches the calf muscle and helps relieve the spasm.
