TNCC SKILLS DEMONSTRATION EXAM 300 ACTUAL
TESTBANK QUESTIONS AND CORRECT ANSWERS WITH
RATIONALE LATEST 2026 ALREADY GRADED A+ ASSURED
PASS
This comprehensive 300-question examination bank is specifically designed
for the TNCC Skills Demonstration exam, covering the full spectrum of
trauma nursing from primary and secondary surveys to definitive
interventions. Each question presents a unique clinical scenario involving
penetrating or blunt trauma, with a focus on critical decision-making,
prioritization, and life-saving procedures. Topics include tension
pneumothorax, cardiac tamponade, hemorrhagic shock, pelvic fractures,
spinal cord injuries, traumatic brain injury with ICP management, chest tube
complications, FAST exam interpretation, and massive transfusion protocols.
No question is repeated, ensuring complete and thorough preparation for the
trauma certification examination.
1. A patient arrives after a motor vehicle crash with a suspected tension
pneumothorax. Which finding during the primary survey is most indicative of this
diagnosis?
A) Absent breath sounds on the left side with hyperresonance
B) Jugular venous distention with hypotension and tracheal deviation
C) Subcutaneous emphysema over the chest wall
D) Bruising over the sternum
Answer: B
Rationale: Tension pneumothorax presents with hypotension, jugular venous
distention, tracheal deviation away from the affected side, and absent breath
sounds. Subcutaneous emphysema is not specific to tension, and hyperresonance
may be seen but is not the most definitive sign. Tracheal deviation is a late but
critical sign requiring immediate needle decompression.
2. During the primary survey, a trauma patient has a patent airway but is breathing
at 32 breaths per minute with shallow effort. What is the priority intervention?
A) Apply a non-rebreather mask at 15 L/min
B) Prepare for endotracheal intubation
C) Place the patient in a supine position
D) Insert a nasopharyngeal airway
Answer: B
,Rationale: A respiratory rate greater than 30 with shallow breathing indicates
respiratory fatigue and impending failure. Endotracheal intubation is the priority to
secure the airway and provide mechanical ventilation. A non-rebreather mask may
temporize but does not address the underlying failure.
3. A patient with a blunt abdominal injury has a positive Focused Assessment with
Sonography for Trauma (FAST) exam. Which finding on the FAST exam indicates
intra-abdominal free fluid?
A) Absence of pericardial effusion
B) Anechoic (black) stripe in the hepatorenal space
C) Hyperechoic bowel loops
D) Shadowing behind the ribs
Answer: B
Rationale: A positive FAST exam is indicated by the presence of anechoic (black)
fluid in dependent areas such as the hepatorenal space (Morison pouch),
splenorenal space, or pelvic view. This free fluid suggests hemoperitoneum from
solid organ injury. The other findings are normal or non-specific.
4. A patient sustains a gunshot wound to the right chest. The chest tube drainage
system has 200 mL of blood in the first hour. What is the most appropriate nursing
action?
A) Document the output and continue monitoring
B) Clamp the chest tube and notify the provider
C) Notify the trauma team of ongoing hemorrhage
D) Increase the suction pressure
Answer: C
Rationale: Output of more than 200 mL per hour or 500 mL in the first 2 hours
indicates significant hemorrhage requiring surgical intervention. The trauma team
must be notified immediately. Clamping a chest tube is contraindicated in this
situation.
5. A patient involved in a fall from height has a Glasgow Coma Scale score of 6.
The nurse should prepare for which immediate intervention?
A) Insert a nasogastric tube
B) Obtain a CT scan of the head
C) Endotracheal intubation
D) Apply cervical collar only
Answer: C
,Rationale: A GCS of 6 is consistent with severe traumatic brain injury and coma.
The patient cannot protect the airway, so endotracheal intubation is the priority. A
CT scan and NG tube are important but secondary to securing the airway.
6. A patient with a pelvic fracture has a hemodynamically unstable pelvic ring
disruption. Which adjunct is most appropriate for temporary stabilization?
A) Skeletal traction
B) Pelvic binder
C) Long leg splint
D) Sandbags around the pelvis
Answer: B
Rationale: A pelvic binder is the standard immediate intervention to reduce pelvic
volume, tamponade bleeding, and provide temporary stabilization in unstable
pelvic fractures. Traction and splints are not appropriate for acute stabilization.
7. A patient presents with a flail chest segment. During the secondary survey,
which finding confirms the diagnosis?
A) Paradoxical chest wall movement during inspiration
B) Absent breath sounds on one side
C) Subcutaneous emphysema over the ribs
D) Tracheal deviation to the contralateral side
Answer: A
Rationale: Flail chest occurs when two or more adjacent ribs are fractured in two
or more places, creating a free-floating segment that moves paradoxically (inward
during inspiration, outward during expiration). This is the hallmark finding.
8. During the primary survey, a patient has a heart rate of 130 and a blood pressure
of 85/60. The nurse administers 1 liter of warmed isotonic crystalloid. The blood
pressure increases to 95/70 but drops again after 15 minutes. What is the most
likely cause?
A) The patient is in neurogenic shock
B) Ongoing hemorrhage
C) The fluid was not warmed enough
D) The patient has a cardiac contusion
Answer: B
Rationale: A transient response to a fluid bolus (blood pressure rises then falls)
indicates ongoing hemorrhage. This is a class III or IV hemorrhagic shock that
requires blood product transfusion and likely operative intervention. Neurogenic
shock would not transiently respond.
, 9. A patient with a suspected spinal cord injury is being log-rolled. Which
statement correctly describes the log-rolling technique?
A) The patient is rolled as a unit while maintaining cervical spine alignment
B) The patient is lifted straight up by four people
C) The patient is rolled onto the side with the head extended
D) The patient is pulled up the bed using a draw sheet
Answer: A
Rationale: Log-rolling requires at least four people: one to maintain head and
cervical spine alignment, and three to roll the patient as a unit without twisting or
bending the spine. This prevents secondary spinal cord injury.
10. A patient arrives with a penetrating injury to the left upper chest and is in
cardiac arrest. Which intervention should the nurse anticipate first?
A) Bilateral needle decompression
B) Pericardiocentesis
C) Left anterolateral thoracotomy
D) Defibrillation
Answer: C
Rationale: In a patient with penetrating chest trauma who loses vital signs en route
or in the emergency department, an emergency department thoracotomy may be
indicated for signs of life. Pericardiocentesis is less definitive; thoracotomy allows
direct control of hemorrhage and relief of tamponade.
11. The primary survey reveals a patient with a patent airway, breathing at 18
breaths per minute, and a pulse of 120. The patient is confused and unable to
follow commands. Which component of the primary survey is being assessed here?
A) Airway with cervical spine protection
B) Breathing and ventilation
C) Circulation with hemorrhage control
D) Disability (neurologic status)
Answer: D
Rationale: Disability is the D of the primary survey and includes a rapid neurologic
assessment using AVPU (Alert, Verbal, Pain, Unresponsive) or GCS. Confusion
and inability to follow commands indicate an altered level of consciousness, which
falls under disability.
12. A patient with blunt abdominal trauma has a pelvic fracture and a positive
FAST. The nurse should prepare for which diagnostic or therapeutic intervention
next?
A) Diagnostic peritoneal lavage
