With regard to musculoskeletal injuries, the zone of injury is defined as the:
- part of the body that sustained secondary injury.
- area of soft-tissue damage surrounding the injury.
- exact part of the bone or joint that was disrupted.
- area of obvious deformity over the site of impact. - Correct Answer-area of soft-tissue damage
surrounding the injury.
A supracondylar or intercondylar fracture is also known as a fracture of the:
- olecranon process.
- radial head.
- distal humerus.
- proximal radius. - Correct Answer-distal humerus.
In general, musculoskeletal injuries should be splinted before moving the patient unless:
- deformity and swelling are present.
- the patient is in severe pain.
- the patient is clinically unstable.
- transport time is less than 15 minutes. - Correct Answer-the patient is clinically unstable.
Which of the following statements regarding compartment syndrome is correct?
1|Page
,- In most cases, compartment syndrome develops within a few minutes after an injury.
- Most cases of compartment syndrome occur following a severe fracture of the pelvis.
- Compartment syndrome typically develops within 6 to 12 hours after an injury.
- Compartment syndrome occurs because of increased pressure within the bone cavity. - Correct
Answer-Compartment syndrome typically develops within 6 to 12 hours after an injury.
Skeletal muscle is attached to the bone by tough, ropelike, fibrous structures called:
- cartilage.
- fascia.
- tendons.
- ligaments. - Correct Answer-tendons.
The MOST significant hazard associated with splinting is:
- reduction in circulation distal to the injury site.
- aggravation of the injury or worsened pain.
- delaying transport of a critically injured patient.
- compression of nerves, tissues, and vasculature. - Correct Answer-delaying transport of a critically
injured patient.
When caring for a patient with a possible fracture of the scapula, the EMT should:
- carefully assess the patient for breathing problems.
- assume that minimal force was applied to the back.
- apply rigid board splints across the chest and back.
- recognize that scapular fractures are life threatening. - Correct Answer-carefully assess the patient for
breathing problems.
An open fracture is MOST accurately defined as a fracture in which:
- a bullet shatters the underlying bone.

,- a large laceration overlies the fracture.
- bone ends protrude through the skin.
- the overlying skin is no longer intact. - Correct Answer-the overlying skin is no longer intact.
A 17-year-old female dislocated her patella while playing soccer. Her knee is flexed and she complains of
severe pain. You should:
- keep her knee flexed and secure it with padded board splints.
- flex her knee slightly more and assess for distal circulation.
- make one attempt to return the patella to its normal position.
- gently straighten her knee and apply a padded board splint. - Correct Answer-keep her knee flexed and
secure it with padded board splints.
In which of the following situations should the EMT splint an injured limb in the position of deformity?
- When distal circulation and neurological functions are absent
- If transport time to the hospital is greater than 20 to 30 minutes
- If a traction splint will be used to immobilize the injured extremity
- If resistance is encountered or the patient experiences severe pain - Correct Answer-If resistance is
encountered or the patient experiences severe pain
A 22-year-old female was ejected from her car after striking a tree head-on. As you approach her, you
note obvious closed deformities to both of her femurs. She is not moving and does not appear to be
conscious. You should:
- apply manual stabilization to both of her femurs.
- administer oxygen and perform a rapid assessment.
- stabilize her head and perform a primary assessment.
- assess for a carotid pulse and assist her ventilations. - Correct Answer-stabilize her head and perform a
primary assessment.

, A 54-year-old male accidentally shot himself in the leg while cleaning his gun. Your assessment reveals a
small entrance wound to the medial aspect of his right leg. The exit wound is on the opposite side of the
leg and is actively bleeding. The patient complains of numbness and tingling in his right foot. You should:
- control the bleeding and cover the wound with a sterile dressing.
- assess distal pulses as well as sensory and motor functions.
- gently manipulate the injured leg until the numbness dissipates.
- manually stabilize the leg above and below the site of injury. - Correct Answer-control the bleeding and
cover the wound with a sterile dressing.
A fracture is MOST accurately defined as a(n):
- disruption in the midshaft of a bone.
- total loss of function in a bone.
- break in the continuity of the bone.
- abnormality in the structure of a bone. - Correct Answer-break in the continuity of the bone.
Crepitus and false motion are:
- positive indicators of a fracture.
- most common with dislocations.
- only seen with open fractures.
- indicators of a severe sprain. - Correct Answer-positive indicators of a fracture.
During your secondary assessment of a 30-year-old male who fell 25 feet, you note crepitus when
palpating his pelvis. Your partner advises you that the patient's blood pressure is 80/50 mm Hg and his
heart rate is 120 beats/min and weak. After completing your assessment, you should:
- log roll the patient onto a long backboard and transport at once.
- perform a focused physical exam with emphasis on the pelvis.
- defer spinal immobilization and transport to a trauma center.
