TNCC Final Exam Practice Questions With
Answers & Rationales
Below is the same former format: A–D choices, the correct answer immediately after each
question, and a detailed rationale. These are original TNCC-style practice questions, not the
actual TNCC final exam or a reproduced answer key.
1. What is the primary purpose of the initial trauma
assessment?
A. Obtain a complete medical history
B. Identify and treat immediate life threats
C. Complete all diagnostic testing
D. Determine the patient's discharge needs
Correct correct answer with Rationale: B. Identify and treat immediate life
threats
Rationale: The initial assessment focuses on rapidly identifying and managing conditions that
can immediately threaten life. Treatment of life-threatening problems takes priority over
obtaining a complete history.
2. In the primary survey, which assessment is performed
first?
A. Circulation
B. Disability
C. Airway
D. Exposure
Correct correct answer with Rationale: C. Airway
Rationale: The primary survey systematically evaluates immediate threats. Airway assessment
is performed early because an obstructed airway can rapidly result in hypoxia and death.
3. A trauma patient has a suspected cervical spine injury.
What is the priority during airway management?
,A. Hyperextend the neck
B. Maintain cervical spine precautions
C. Place the patient in Trendelenburg position
D. Delay airway assessment
Correct correct answer with Rationale: B. Maintain cervical spine precautions
Rationale: Patients with mechanisms suggesting cervical injury should have spinal precautions
maintained while the airway is assessed and managed.
4. Which finding is most concerning for an immediately
compromised airway?
A. Mild headache
B. Hoarse voice with increasing respiratory distress
C. Bruising on the lower leg
D. Mild abdominal tenderness
Correct correct answer with Rationale: B. Hoarse voice with increasing
respiratory distress
Rationale: Hoarseness, stridor, swelling, and increasing respiratory effort may indicate airway
injury or obstruction. Progressive airway edema can make later airway management more
difficult.
5. Which finding most strongly indicates inadequate
oxygenation?
A. SpO₂ of 98%
B. Cyanosis and altered mental status
C. Warm skin
D. Respiratory rate of 16/min with normal effort
Correct correct answer with Rationale: B. Cyanosis and altered mental status
Rationale: Cyanosis and altered mental status are concerning findings that may accompany
significant hypoxemia. The trauma nurse should rapidly assess and intervene.
,6. A patient with chest trauma develops severe respiratory
distress and hypotension. Which condition should be
considered?
A. Tension pneumothorax
B. Simple ankle fracture
C. Isolated abdominal contusion
D. Mild concussion
Correct correct answer with Rationale: A. Tension pneumothorax
Rationale: Severe respiratory distress, hypotension, and significant chest trauma can indicate
tension pneumothorax, an immediately life-threatening condition requiring urgent intervention.
7. Which assessment finding is characteristic of a tension
pneumothorax?
A. Improved breath sounds bilaterally
B. Severe respiratory distress with unilateral decreased breath sounds
C. Bradycardia with normal breathing
D. Isolated wrist pain
Correct correct answer with Rationale: B. Severe respiratory distress with
unilateral decreased breath sounds
Rationale: A tension pneumothorax can cause respiratory compromise and obstruct venous
return. Unilateral diminished or absent breath sounds may occur.
8. Which condition involves blood accumulating in the
pleural space?
A. Hemothorax
B. Pneumothorax
C. Cardiac tamponade
D. Pulmonary embolism
Correct correct answer with Rationale: A. Hemothorax
, Rationale: A hemothorax is accumulation of blood within the pleural cavity, commonly
resulting from chest trauma.
9. Which finding is associated with cardiac tamponade?
A. Hypotension and muffled heart sounds
B. Increased urine output
C. Bilateral clear breath sounds with hypertension
D. Isolated leg swelling
Correct correct answer with Rationale: A. Hypotension and muffled heart sounds
Rationale: Cardiac tamponade results from pressure around the heart that impairs cardiac filling.
Hypotension and muffled heart sounds can be associated findings.
10. Which type of shock is most commonly associated with
significant blood loss?
A. Neurogenic
B. Hemorrhagic/hypovolemic
C. Septic
D. Anaphylactic
Correct correct answer with Rationale: B. Hemorrhagic/hypovolemic
Rationale: Trauma-related blood loss decreases circulating blood volume and can produce
hemorrhagic shock.
11. Which assessment finding can be an early sign of shock?
A. Tachycardia
B. Severe bradycardia in every patient
C. Increased urine output
D. Warm, dry skin in all cases
Correct correct answer with Rationale: A. Tachycardia
