First Aid FREE First Aid Bone, Muscle, and Joint Injuries Questions and Answers 3

Question 1

During a sporting event, an athlete's knee bends sideways and they cannot bear weight. Which structure is most likely injured?

Accepted Answer

Ligament

Answer

Sideways force on the knee that causes instability and inability to bear weight is classic for a ligament sprain or tear, such as an MCL or ACL injury.

Question 2

When applying ice for a musculoskeletal injury, what precaution must you take to prevent frostbite?

Accepted Answer

Place a cloth or towel between the ice pack and the skin

Answer

Always wrap ice packs in a cloth barrier to prevent frostbite; direct application can freeze and damage skin tissue.

Question 3

Which of the following is a classic sign of a fracture that distinguishes it from a bruise or sprain?

Accepted Answer

Point tenderness directly over the bone

Answer

Point tenderness localized directly over a bone is a reliable indicator of a fracture, unlike the diffuse tenderness seen with sprains or bruises.

Question 4

A construction worker falls and has an angulated (bent at odd angle) forearm with intact skin. What is the first aid priority?

Accepted Answer

Splint the arm in the position found and activate EMS

Answer

Angulated fractures should be splinted in the position found because attempting to straighten them can worsen bone, vessel, or nerve damage.

Question 5

What is the correct way to check circulation after applying a splint to a fractured extremity?

Accepted Answer

Assess capillary refill, pulse, sensation, and movement distal to the splint

Answer

Checking capillary refill time, distal pulse, sensation, and movement confirms that the splint is not too tight and circulation remains intact.
