Why is it important to understand biomechanics as it relates to
types of energy forces and MOI?
Understanding how energy forces affect the human body is
useful for better anticipating effects of trauma on a person
What are common MOIs that result in trauma
blunt, penetrating, blast
What injuries are expected in each stage of a blast (explosion)
Primary (direct blast effects) - pulmonary barotrauma, tympanic
membrane rupture, abdominal hemorrhage/perforation, globe
rupture, mild TBI
Secondary (projectiles) - penetrating or blunt injuries, eye
penetration
,Page 2 of 40
Tertiary (propulsion of body onto hard surface) -
blunt/penetrating injury, fracture, traumatic amputation,
closed/open TBI
Quaternary (heat/fume/combustion) - burns, crush injury,
asthma, COPD, angina, hyperglycemia, hypertension
Quinary (hazardous materials) - depends on agent (bacteria,
radiation, chemical etc)
Why is it important to use a systemic approach to the initial
assessment of a trauma patient?
To maximize outcomes and reduce the risk of undiscovered
injuries.
What is included in the preparation for a trauma patient?
Activate the Trauma Team and assign roles
Prepare the room/equipment
Don PPE
Consider safety threats
Decontamination
,Page 3 of 40
What information is obtained in the general impression
overall status and identification of hemorrhage; identify all life
threatening injuries; APVU
What does the A-J mnemonic stand for?
A - airway/alertness
B - breathing/ventilation
C - circulation, control of hemorrhage
D - disability (neuro status)
E - exposure and environmental control
F - full set of vitals/family presence
G - get adjusts/give comfort
L - labs
M - monitor cardiac status
N - nasogastric/orogastric
O - oxygenation
P - pain
H - history/head to toe
I - inspect posterior
J - just keep reevaluating
, Page 4 of 40
What does alertness include in airway assessment?
APVU
When an intervention is taken during the primary survey, what
must the nurse do after the intervention?
reassess
What are componants of secondary survey?
history
head to toe assessment
inspect posterior surfaces
reassessment
What should nurse reevaluate?
all aspects of the primary and secondary assessments
V - vitals
I - injuries/interventions
P - primary survey
