Question 1
Why is it important to understand biomechanics as it relates to types
of energy forces and MOI?
A) To predict the exact outcome of every trauma patient
B) To better anticipate the effects of trauma on the human body
C) To determine the patient's insurance coverage
D) To document injuries for legal purposes
Answer: B) To better anticipate the effects of trauma on the human
body
Rationale: Understanding biomechanics and energy forces allows
healthcare providers to anticipate potential injury patterns based on the
mechanism of injury (MOI). This knowledge helps clinicians maintain a high
index of suspicion for specific injuries, guide assessment priorities, and
improve outcomes through early recognition and intervention.
Question 2
Which of the following are common mechanisms of injury (MOIs) that
result in trauma?
A) Blunt, penetrating, and thermal
B) Blunt, penetrating, and blast
C) Thermal, chemical, and electrical
D) Falls, MVCs, and stabbings
,Answer: B) Blunt, penetrating, and blast
Rationale: The three common MOIs that result in trauma are blunt,
penetrating, and blast injuries. Each mechanism produces distinct injury
patterns and requires specific assessment and management approaches.
While thermal injuries (burns) can occur, they are not classified as a primary
MOI category in this context.
Question 3
A patient arrives after an explosion. Which injury would be expected
from the primary phase of a blast injury?
A) Penetrating trauma from flying debris
B) Fractures from being thrown against a wall
C) Pulmonary barotrauma and tympanic membrane rupture
D) Burns from thermal effects
Answer: C) Pulmonary barotrauma and tympanic membrane rupture
Rationale: Primary blast injuries result from the direct effects of the blast
wave overpressure on the body. The most common injuries include
pulmonary barotrauma, tympanic membrane rupture, abdominal
hemorrhage/perforation, globe rupture, and mild TBI. These occur due to
pressure changes affecting air-filled organs.
Question 4
During which stage of a blast injury would you expect penetrating or
blunt injuries from projectiles?
A) Primary
B) Secondary
, C) Tertiary
D) Quaternary
Answer: B) Secondary
Rationale: Secondary blast injuries occur when projectiles (debris, shrapnel,
glass) are propelled by the explosion and cause penetrating or blunt
injuries. Eye penetration is a specific concern in this phase. Each blast phase
produces characteristic injury patterns that guide assessment and
treatment priorities.
Question 5
A patient involved in an explosion has burns, crush injuries, and
exacerbation of asthma. Which stage of blast injury does this
represent?
A) Primary
B) Secondary
C) Tertiary
D) Quaternary
Answer: D) Quaternary
Rationale: Quaternary blast injuries include all other explosion-related
injuries not classified in the first three phases. These include burns from
heat/fumes/combustion, crush injuries from structural collapse, and
exacerbations of chronic conditions such as asthma, COPD, and angina.
Hyperglycemia and hypertension may also occur.
