questions and answers
Why is it important to understand biomechanics as it relates to
types of energy forces and MOI? -
correct answer ✅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 -
correct answer ✅blunt, penetrating, blast
What injuries are expected in each stage of a blast (explosion) -
correct answer ✅Primary (direct blast effects) - pulmonary
barotrauma, tympanic membrane rupture, abdominal
hemorrhage/perforation, globe rupture, mild TBI
Secondary (projectiles) - penetrating or blunt injuries, eye
penetration
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)

questions and answers
Why is it important to use a systemic approach to the initial
assessment of a trauma patient? -
correct answer ✅To maximize outcomes and reduce the risk of
undiscovered injuries.
What is included in the preparation for a trauma patient? -
correct answer ✅Activate the Trauma Team and assign roles
Prepare the room/equipment
Don PPE
Consider safety threats
Decontamination
What information is obtained in the general impression -
correct answer ✅overall status and identification of hemorrhage;
identify all life threatening injuries; APVU
What does the A-J mnemonic stand for? -
correct answer ✅A - airway/alertness
B - breathing/ventilation
C - circulation, control of hemorrhage
D - disability (neuro status)

L - labs
M - monitor cardiac status
N - nasogastric/orogastric
O - oxygenation
P - pain
H - history/head to toe

What does alertness include in airway assessment? -
correct answer ✅APVU
When an intervention is taken during the primary survey, what
must the nurse do after the intervention? -
correct answer ✅reassess

questions and answers
What are componants of secondary survey? -
correct answer ✅history
head to toe assessment
inspect posterior surfaces
reassessment
What should nurse reevaluate? -
correct answer ✅all aspects of the primary and secondary
assessments
V - vitals
I - injuries/interventions
P - primary survey
P - pain
What are the differences in ventilation, diffusion and perfusion? -
correct answer ✅ventilation - mechanical process of breathing
diffusion - movement of gases (higher to lower concentration)
perfusion - movement of blood through circulatory system
