25
What is a hemopneumothorax?
When both blood and air are filling the pleural space
26
What is paper bag syndrome?
When air fills lung during a collision and causes the lung to pop, creating a pneumothorax
27
When does traumatic asphyxia occur?
Sudden severe compression someone's chest producing a rapid increase in pressure. Characterized by distended neck veins, cyanosis in the face and neck, and hemorrhage in sclera.
28
What is commotio cordis?
Injury caused by a sudden, direct blow to chest during a critical portion of the heartbeat may result in immediate arrest v-fib responds to defibrillation within first two minutes of the injury
29
Should you attempt to put intestines back into abdominal cavity during an abdominal evisceration?
No.
30
What should be done during an abdominal evisceration?
keep pt warm cover with moist dressing, then a dry dressing, then an occlusive dressing and seal. keep dressings somewhat loose.
31
How should pelvic injuries be assessed during physical examination? If unstable, what should be done.
push down on either side. If pelvis feels unstable, secure with a bedsheet.
32
What should hip fractures be treated with? What sort of stretcher should be used with these sorts of pts?
in order to keep feet apart (abducted), do not use bed sheet. Instead tie using towels or blankets to tie legs together. Use scoop stretcher
33
What is a common visual indicator of a mid-shaft femur fracture? What sort of splint should be used for this condition?
One leg is shorter than the other, and there is tenderness in the area. traction splint
34
When can you use a hare traction splint?
isolated, closed, mid-shaft femur fracture
35
What is splinting by fixation?
preventing broken bone from jostling.
36
what is a greenstick fracture? comminuted? pathologic?
greenstick: incomplete fracture that passes only partway through the shaft of bone. comminuted: fracture in which bone is broken into more than two fragments pathologic: a fracture of weakened or diseased bone
37
What is an oblique fracture? transverse? spiral? incomplete?
oblique: bone broken at an angle across the bone spiral: a type of oblique caused by a twisting force transverse: a fracture that occurs straight across the bone incomplete: a fracture that does not run completely through the bone
38
What is the general management for extremity injuries?
1. Manual stabilization 2. Assessment of distal neurological function and circulation 3. Application of splint 4. Reassessment of distal neurovascular function 5. apply cold pack 6. transport (preferably to trauma facilities with orthopedic element)
39
When is fixation used vs traction splint?
traction is for isolated mid shaft femur fracture. Fixation is everything else
40
How should long bone fractures be treated?
1. if extremity is either absent of distal pulse OR angulated you may attempt to realign to normal anatomical position 1 time 2. if extremity possesses distal pulse and is not angulated, splint in place GO TO TRAUMA CENTER
41
How should joint fractures be treated
1. if extremity is either absent of distal pulse you may attempt to realign to normal anatomical position 1 time 2. if extremity possesses distal pulse, splint in place GO TO TRAUMA CENTER IF REALIGNMENT DOES NOT WORK
42
What is the difference between a sprain and a strain?
sprain: ligament (bone to bone) strain: muscle and tendon (muscle to bone)
43
What the tendons and ligaments that connect to the patella?
quadriceps tendon and patellar ligament
44
What should be done with patella dislocation?
put patella back into position, if dislocation is obvious. Check protocols in region to see if OLMC should be contacted first
45
Describe the process of patellar relocation
gradually extend knee, while at same time, a second provider applies pressure on patella towards midline. when straight, place entire knee joint in a knee immobilizer or splint
46
What is compartment syndrome characterized by?
pain that is out of proportion to injury pain on passive stretching of muscles withing compartment pallor swelling decreased sensation and power
47
Can anything be done in prehospital syndrome for compartment syndrome?
Besides mentioning suspect CS to ER staff, no
48
What stretchers should for pts laying supine or prone after a collision?
long board or scoop stretcher due to suspected spinal injury
49
Can spine immobilization be achieved in seated position?
no, must be in supine position. head of stretcher must be elevated <30 degrees
50
What are the four techniques for controlling bleeding?
1. focused direct pressure 2. dressing wound (hemostatic dressing if applicable) 3. pressure bandages 4. Tourniquet (if extremity wound)
51
If a wound is not amenable to a tourniquet what should be considered?
packing in the axillary and groin
52
What are the techniques for treating amputations?
1. aggressive bleeding control 2. wrap amputated area with moist dressing 3. place amputated part in bag 4. place into second bag with ice or cold packs
53

A 17-year-old male was shot in the right anterior chest during an altercation with a gang member. As your partner is applying 100% oxygen, you perform a rapid secondary assessment and find an open chest wound with a small amount of blood bubbling from it. You should:
apply an occlusive dressing to the wound and continue your assessment
58
Functions of dressings and bandages include all of the following, EXCEPT: control of external hemorrhage protection from further injury immobolization of injury preventionn of contamination
immobolization of injury
59
Burns are classified according to:
depth and extent
