Multiple Choice Questions &
Answers/Trauma Nursing Core Course
Practice Test & Verified solutions.
SECTION 1: MECHANISM OF INJURY & BIOMECHANICS
Q1. Why is it important to understand biomechanics as it relates to types of
energy forces and MOI?
A) To document the accident scene accurately
B) To anticipate effects of trauma on the body and predict injury patterns
C) To determine legal liability in motor vehicle crashes
D) To complete the primary survey faster
Correct Answer: B
Rationale: Understanding how energy forces affect the human body allows providers to
anticipate injury patterns and severity before completing the full assessment. This guides
the trauma nursing process and prioritization of care.
Q2. Which of the following is NOT a common mechanism of injury resulting in
trauma?
A) Blunt trauma
B) Penetrating trauma
C) Thermal trauma
D) Blast trauma
Correct Answer: C
,Rationale: The three common MOIs resulting in trauma are blunt, penetrating, and blast
injuries. Thermal injuries (burns) are a type of injury, not a mechanism of injury per the
TNCC framework.
Q3. A patient involved in an explosion presents with tympanic membrane rupture
and pulmonary barotrauma. These injuries are characteristic of which blast phase?
A) Secondary blast injury
B) Tertiary blast injury
C) Primary blast injury
D) Quaternary blast injury
Correct Answer: C
Rationale: Primary blast injuries result from the direct effects of the blast overpressure
wave on gas-containing organs. Tympanic membrane rupture, pulmonary barotrauma,
and abdominal hemorrhage are hallmark findings.
Q4. A patient from an explosion has a penetrating eye injury from flying debris.
This is classified as:
A) Primary blast injury
B) Secondary blast injury
C) Tertiary blast injury
D) Quinary blast injury
Correct Answer: B
Rationale: Secondary blast injuries result from projectiles propelled by the explosion,
causing penetrating or blunt injuries. Eye penetration is a classic example.
Q5. A patient is thrown against a wall during an explosion and sustains a femur
fracture and traumatic amputation. These injuries are from which blast phase?
,A) Primary blast injury
B) Secondary blast injury
C) Tertiary blast injury
D) Quaternary blast injury
Correct Answer: C
Rationale: Tertiary blast injuries occur when the blast wind propels the victim into
stationary objects, causing blunt injuries, fractures, traumatic amputations, and TBI.
Q6. A patient from an explosion has smoke inhalation and burn injuries. These are
classified as:
A) Primary blast injury
B) Secondary blast injury
C) Tertiary blast injury
D) Quaternary blast injury
Correct Answer: D
Rationale: Quaternary blast injuries include all other explosion-related injuries from heat,
flames, fumes, and combustion, including burns, crush injuries, and exacerbation of
chronic conditions.
Q7. A patient from an explosion is exposed to radiation or chemical agents. This is
categorized as:
A) Primary blast injury
B) Secondary blast injury
C) Quaternary blast injury
D) Quinary blast injury
Correct Answer: D
Rationale: Quinary blast injuries are specific to hazardous material exposure including
bacteria, radiation, or chemicals from the blast environment.
, Q8. How does understanding kinematic concepts assist the trauma care provider?
A) By determining the patient's Glasgow Coma Scale score
B) By anticipating the types of injuries that may be present
C) By identifying the need for surgical intervention
D) By calculating the exact severity of injuries
Correct Answer: B
Rationale: Kinematic concepts and mechanism of injury help providers anticipate injury
patterns and evaluate the need for specific diagnostic tests, even before the complete
physical exam is performed.
SECTION 2: TRAUMA NURSING PROCESS (TNP)
Q9. The Trauma Nursing Process (TNP) is a systematic approach to trauma care.
What is the correct sequence of steps?
A) Assessment, Planning, Implementation, Evaluation, Diagnosis
B) Assessment, Diagnosis, Planning, Implementation, Evaluation
C) Diagnosis, Assessment, Planning, Implementation, Evaluation
D) Planning, Assessment, Diagnosis, Implementation, Evaluation
Correct Answer: B
Rationale: The TNP follows the same sequence as the nursing process: Assessment (rapid
identification of life threats), Diagnosis (identifying actual/potential problems), Planning
(prioritizing interventions), Implementation (executing the plan), and Evaluation
(determining effectiveness).
Q10. The trauma nursing process differs from the traditional nursing process in
which way?
