week 7 - trauma

Question 1

Define MOI

Answer 1

is the process by which forces are exchanged between a person and an energy source > producing injury

• the greater the energy/ force = the greater the injury

Question 2

MOI - Blunt injury

- types of mechansims

Answer 2

• MVA
• Falls
• assult
• contact sports
• often involves multipule other injuries

Question 3

MOI - Blunt injury

- what is it caused by?

Answer 3

caused by a change in energy (velocity or sudden force)

- energy is distributed over a larger area than penertrating injury

Question 4

MOI - Blunt injury

- what can it result in?

Answer 4

results in damage to underlying tissue, sometimes without obvious damage to this skin

Question 5

MOI - penetrating injury

Answer 5

occurs where the skin is penertrated resulting in damage to the underliying tissues and organs

• results in damage along the path of penetration

Question 6

MOI - penetrating injury

- what does the extent of the injury depend on?

Answer 6

• energy behind the object
• length of object
• angle of entry

Question 7

MOI - penetrating injury

- indication of damage?

Answer 7

appearance of the wound at the skin is not an indicator of damage to the underlying structures

• visceral damage occurs in 30% of stab wounds

Question 8

Mild Trauma - 3 characteristics

Answer 8

• usually single system
• not life threatening
• not limb threatening

Question 9

Major Trauma - 3 characteristics

Answer 9

• life or limb threatening
• requires immediate interventions
• may be multipule injuries

Question 10

Major Trauma - MOI

Answer 10

• MVA >30km/h
• vechile roll over
• ejection from vechile
• fall over 3 m
• explosion

Question 11

Major Trauma - potential injuries

Answer 11

• suspected spinal cord injury
• # pelvis
• pulseless limb
• dislocation with vascular compromise
• blast injuries
• severe crush injuries
• burns > 20% TBSA

Question 12

Major Trauma - signs (vital signs)

Answer 12

• SBP < 14
• 02 < 90%
• RR < 10 or > 30
