Based on ENA Trauma Nursing Core Course (TNCC) 8th Edition Guidelines

Instructions: Read each question carefully. The correct answer is highlighted in bold cyan. Each question includes a
rationale with clinical references.
DOMAIN 1: Trauma Nursing Process & Initial Assessment
1. According to the ENA TNCC 8th Edition, what is the correct sequence of the trauma nursing
process?
A. B.
Intervention, Assessment,
assessment, intervention,
evaluation, evaluation,
reassessment reassessment
C. D.
Evaluation, Reassessment,
assessment, intervention,
intervention, assessment,
reassessment evaluation
Correct Answer: B. Assessment, intervention, evaluation, reassessment
Rationale: The ENA TNCC 8th Edition defines the trauma nursing process as a systematic approach following the
sequence: assessment, intervention, evaluation, and reassessment. This cyclical process ensures that life-threatening
conditions are identified rapidly, interventions are performed, their effectiveness is evaluated, and the patient is
continuously reassessed for changes in condition. The other sequences are incorrect because assessment must always
precede intervention to avoid inappropriate or harmful actions.

Correct Answer: B. Ensure personal safety and scene security
Rationale: Per ENA TNCC and PHTLS guidelines, the first priority at any trauma scene is ensuring personal safety
and scene security. A nurse who becomes a victim cannot help others. Scene safety includes assessing for hazards such
as fire, traffic, electrical lines, chemical exposure, and structural instability. Triage and patient care begin only after
the scene is declared safe. This is a fundamental principle emphasized in both TNCC and ATLS.
3. Which type of mechanism of injury is most associated with deceleration forces and injuries to solid
organs such as the liver and spleen?
A. B. Blast
Penetrating injury
trauma from from an
a stab explosion
wound
C. Blunt D.
trauma Thermal
from a injury
motor from a
vehicle house

with rapid
deceleration
Correct Answer: C. Blunt trauma from a motor vehicle collision with rapid deceleration
Rationale: Blunt trauma from rapid deceleration, such as in a motor vehicle collision, is most commonly associated
with injuries to solid organs like the liver and spleen. During deceleration, organs continue to move forward while the
body decelerates, causing shearing forces at attachment points. The liver and spleen are particularly vulnerable
because of their size and ligamentous attachments. Penetrating trauma typically follows the path of the injuring object,
and blast injuries cause a combination of primary, secondary, tertiary, and quaternary effects.

4. During START triage, a patient is found breathing at 36 breaths per minute with absent radial
pulses. What is the correct triage category?
A. Green B. Yellow (Delayed)
(Minor)
C. Red D. Black
(Immediate) (Expectant/Deceased)
Correct Answer: C. Red (Immediate)
Rationale: In START (Simple Triage and Rapid Treatment) triage, patients are first assessed for ability to walk, then
for respirations, perfusion, and mental status. A patient breathing more than 30 breaths per minute is triaged as Red
(Immediate) because tachypnea indicates hypoperfusion or respiratory distress. Absent radial pulses further confirm
shock. Green patients can walk; Yellow patients are ambulatory but have injuries requiring care within hours; Black
patients are deceased or have nonsurvivable injuries. This protocol follows the MCI framework endorsed by TNCC.
5. A patient presents after a fall from a two-story building. The initial hands-off assessment reveals no
obvious external bleeding, but the patient is pale and diaphoretic. What is the most likely cause of
these findings?
A. Spinal B. Internal
cord injury hemorrhage
with causing
neurogenic compensated
shock shock
C. D. Fat
Traumatic embolism
brain syndrome
injury with
increased
ICP
Correct Answer: B. Internal hemorrhage causing compensated shock
Rationale: Pale, cool, diaphoretic skin in a trauma patient with a significant mechanism of injury (fall from height) is
the classic presentation of compensated hemorrhagic shock. The patient may maintain a normal blood pressure initially
due to compensatory vasoconstriction and tachycardia, but end-organ perfusion is already compromised. The ENA
TNCC emphasizes that internal bleeding may not be visible externally, and a high index of suspicion based on
mechanism of injury is critical. Neurogenic shock presents with warm, dry skin and bradycardia, which is a distinctly
different presentation.
6. A nurse performing a hands-off initial assessment of a trauma patient identifies a large contusion to
the left upper quadrant of the abdomen and deformity of the left forearm. Which of these findings
should be addressed FIRST according to TNCC priorities?

Correct Answer: C. Neither finding should be addressed until the primary survey (ABCDE) is
complete
Rationale: The ENA TNCC teaches that the hands-off initial assessment (also called the initial impression) is used to
identify obvious life threats and form a general impression, but definitive management must wait until the primary
survey (ABCDE) is complete. The ABCDE approach ensures that the most life-threatening conditions—catastrophic
hemorrhage, airway compromise, breathing problems, circulatory failure, and disability—are addressed before any
secondary injuries. Addressing either the abdominal contusion or forearm deformity before completing the primary
survey could delay treatment of a more critical problem.
DOMAIN 2: Primary Survey (ABCDE) & Resuscitation Priorities
7. During the primary survey of a trauma patient with a suspected cervical spine injury, which airway
maneuver should the nurse use to open the airway?
