What is the difference between a fracture and a dislocation?
- AA fracture affects only children, a dislocation only adults
- BA dislocation is a break in the bone
- CThey are the same condition
- DA fracture is a break in the bone; a dislocation is when a bone is displaced from a joint✓
Answer: A fracture is a break in the bone structure. A dislocation is when a bone is forced out of its normal position in a joint.
What are the signs of a suspected fracture?
- ARedness, heat and swelling only, with completely normal movement of the limb still possible
- BPain, swelling, deformity, inability to move, and crepitus (grinding sensation)✓
- CPale skin only
- DOnly severe pain
Answer: Signs include pain, swelling, deformity, inability to move the limb, bruising, and sometimes a grinding sensation (crepitus).
What is RICE treatment for sprains and strains?
- ARest, Immobilise, Compress, Exercise
- BRestrict, Ice, Cool, Extend
- CRaise, Ice, Cool, Elevation
- DRest, Ice, Compression, Elevation✓
Answer: RICE stands for Rest (stop activity), Ice (apply for 15-20 minutes), Compression (support bandage), and Elevation (raise the limb).
What is the correct way to apply ice to a sprain?
- AWrap ice in a cloth and apply for 15-20 minutes, remove, and reapply if needed✓
- BApply very hot water to the sprain instead, to relax the muscles around the joint
- CDo not apply anything cold at all, because cooling a sprain slows the healing process
- DApply ice directly to the skin and hold it there for as long as the casualty can tolerate it
Answer: Wrap ice in a cloth or use an ice pack and apply for 15-20 minutes. Do not apply ice directly to skin as it can cause ice burn.
How should you immobilise a suspected arm fracture?
- AApply a sling to support the arm against the body✓
- BLeave it freely moveable
- CEncourage movement to prevent stiffness
- DWrap it tightly with elastic bandage only
Answer: Use a sling to support the injured arm against the body, preventing movement and reducing pain. This can be made from a triangular bandage.
What should you do for a suspected spinal injury?
- APerform CPR immediately
- BImmobilise the spine and avoid unnecessary movement; only move if there is immediate danger✓
- CGently stretch and straighten the spine to realign the vertebrae before the casualty is moved anywhere
- DMove the casualty immediately
Answer: Do not move a casualty with suspected spinal injury unless there is immediate danger. Immobilise and support the head and neck.
What are the signs of a dislocated joint?
- AA dislocation shows no visible signs and can only be confirmed by an X-ray at hospital
- BMild pain only, with the joint still moving through its normal range
- CRedness only
- DDeformity, severe pain, loss of function, swelling, and bruising✓
Answer: A dislocated joint shows obvious deformity (the bone appears out of place), severe pain, swelling, bruising, and inability to move the joint.
What should you do if you encounter a dislocated joint?
- AGive pain relief and exercise the joint
- BApply heat to the joint
- CAttempt to realign the joint immediately, before the muscles around it go into spasm
- DImmobilise in the position found, apply ice, and call 999✓
Answer: Do not attempt to realign a dislocated joint. Immobilise it in the position found, apply ice (wrapped), and seek medical help.
What is the difference between a strain and a sprain?
- AThe terms mean the same thing
- BA strain is damage to muscle or tendon; a sprain is damage to ligaments✓
- COnly sprains require treatment
- DA sprain is damage to muscle; a strain is damage to ligaments
Answer: A strain is damage to a muscle or tendon (muscle pull). A sprain is damage to a ligament (joint twist).
What is the proper sling position for an arm fracture?
- AArm bent at approximately 90 degrees and supported against the body✓
- BArm raised above the level of the heart and held there to reduce the swelling
- CArm held straight down by the side of the body and bandaged firmly to the chest
- DArm folded behind the back and held there with a bandage passed around the chest
Answer: The arm should be bent at approximately 90 degrees at the elbow and supported in a sling against the body to prevent movement.
How can you tell if a fracture is open or closed?
- AA closed fracture has no wound; an open fracture has a wound and possible bone protruding✓
- BFractures are never open, because the skin always remains intact over the site of the break itself
- CEvery fracture is an open fracture, because a broken bone always tears through the skin above it
- DAn open fracture has no wound; the term simply means the bone has broken into two separate pieces
Answer: A closed fracture has no wound. An open (compound) fracture has a wound and possibly bone protruding through the skin.
What is the primary concern with an open fracture?
- AThere are no special concerns beyond those of any other broken bone
- BInfection due to the open wound and possible severe bleeding✓
- CPreventing movement of the joints above and below the break, which is the only real concern
- DPain management only, since an open fracture heals in the same way as a closed one
Answer: Open fractures have a high risk of infection and may have severe bleeding. Treat the wound, control bleeding, immobilise, and seek urgent medical help.
How should you treat a casualty with a suspected pelvis fracture?
- AApply a compression bandage and elevate the legs
- BKeep them lying flat with support under the knees, immobilise, and call 999✓
- CHelp them walk
- DMassage the area
Answer: Keep the casualty lying flat with support under the knees, avoid movement, and call 999 immediately. Pelvic fractures can cause severe internal bleeding.
What complications can arise from a fracture?
- AOnly pain
- BOnly bruising
- CShock, damage to blood vessels and nerves, fat embolism, and infection✓
- DThere are never any complications once the bone has been immobilised properly
Answer: Serious complications can include shock, blood vessel/nerve damage, fat embolism, and infection (especially with open fractures).
How should you support a suspected leg fracture?
- AUse pillows or padding to support the leg in a comfortable position and prevent movement✓
- BApply a very tight bandage around the whole leg to hold the broken ends of the bone firmly together
- CEncourage the casualty to exercise the leg gently so that the joint does not stiffen up while waiting
- DLeave the leg completely unsupported so that the casualty can find the position that hurts them least
Answer: Support the injured leg with pillows or padding to keep it comfortable and prevent movement. This reduces pain and prevents further injury.
What is compartment syndrome?
- AA mental health disorder
- BA type of headache
- CIt never arises in first aid situations because swelling inside a limb always settles on its own
- DA serious condition where swelling within a muscle compartment cuts off blood supply✓
Answer: Compartment syndrome occurs when swelling within a fascial compartment increases pressure and cuts off blood supply. It causes severe pain and requires urgent intervention.
How long should ice be applied to an acute soft tissue injury?

Answer: Apply ice for 15-20 minutes to acute soft tissue injuries. This can be repeated if needed, allowing the skin to warm between applications.
What should be done for a casualty with a knee injury?
- AImmobilise, apply ice, elevate, and seek medical advice for severe injuries✓
- BForce the knee through its full range of movement to check whether it is broken
- CKeep the leg straight

How should you handle a casualty with a rib fracture?
- AApply heat to the chest wall and strap the ribs tightly with a broad bandage so that they cannot move at all
- BSupport the chest with padding or a bandage, encourage gentle breathing, and seek medical advice✓
- CImmobilise the chest completely by binding both arms tightly across it and taping them down firmly
- DEncourage deep breathing and movement
Answer: Support the chest with padding or a support bandage, encourage gentle breathing to prevent pneumonia, and seek medical advice. Avoid complete immobilisation.
