TNCC FINAL EXAM TEST BANK 2026 – VERIFIED QUESTIONS, ANSWERS & EXPERT
RATIONALE (A+ GRADED STUDY GUIDE)
This test bank contains 300 verified multiple-choice questions designed to prepare
you for the TNCC (Trauma Nursing Core Course) final exam. Read each question
carefully, attempt an answer before checking the highlighted correct option, and
study the EXPERT RATIONALE to reinforce your clinical reasoning.
QUESTION 1 A trauma nurse is assessing a patient who was involved in a high-
speed motor vehicle collision. Which of the following is the FIRST priority in the
primary survey?
A. Control of external hemorrhage
B. Assessment of neurological status
C. A – Airway maintenance with cervical spine protection
D. Breathing and ventilation
E. Exposure and environmental control
CORRECT ANSWER: C – Airway maintenance with cervical spine
protection EXPERT RATIONALE: The primary survey follows the ABCDE
approach. Airway with simultaneous cervical spine protection is always the first
priority, as an obstructed airway can cause death within minutes.
QUESTION 2 During the primary survey, a patient has absent breath sounds on the
left side with tracheal deviation to the right. What is the MOST likely diagnosis?
A. Hemothorax
B. Flail chest
C. Cardiac tamponade
D. Tension pneumothorax
,E. Open pneumothorax
CORRECT ANSWER: D – Tension pneumothorax EXPERT RATIONALE:
Tension pneumothorax presents with absent breath sounds on the affected side,
tracheal deviation away from the affected side, hypotension, and respiratory
distress. Immediate needle decompression is required.
QUESTION 3 Which of the following assessment findings is MOST consistent with
cardiac tamponade?
A. Tracheal deviation and absent breath sounds
B. Paradoxical chest wall movement
C. Muffled heart sounds, hypotension, and distended neck veins
D. Hyperresonance on percussion
E. Subcutaneous emphysema
CORRECT ANSWER: C – Muffled heart sounds, hypotension, and
distended neck veins EXPERT RATIONALE: Beck's triad — muffled heart
sounds, hypotension, and jugular venous distension — is the classic presentation of
cardiac tamponade. Immediate pericardiocentesis is the intervention.
QUESTION 4 A patient arrives with a gunshot wound to the abdomen. The nurse
notes evisceration of bowel. What is the PRIORITY nursing intervention?
A. Attempt to replace the bowel into the abdominal cavity
B. Apply a dry, sterile dressing
C. Prepare the patient for immediate surgery
D. Cover the evisceration with a moist sterile dressing
E. Insert a nasogastric tube
CORRECT ANSWER: D – Cover the evisceration with a moist sterile
dressing EXPERT RATIONALE: Eviscerated organs should never be pushed
,back. The correct intervention is to cover them with a moist, sterile dressing to
prevent drying and further contamination while preparing for surgery.
QUESTION 5 Which Glasgow Coma Scale (GCS) score indicates severe traumatic
brain injury?
A. 13–15
B. 12–14
C. 10–12
D. 9–11
E. 3–8
CORRECT ANSWER: E – 3–8 EXPERT RATIONALE: A GCS score of 3–8
indicates severe TBI. Scores of 9–12 indicate moderate TBI, and 13–15 indicate mild
TBI. Severe TBI requires aggressive airway management including early intubation.
QUESTION 6 A trauma patient has a blood pressure of 80/50 mmHg, heart rate of
128 bpm, and cool clammy skin. Which class of hemorrhagic shock does this MOST
likely represent?
A. Class I
B. Class II
C. Class III
D. Class IV
E. Neurogenic shock
CORRECT ANSWER: C – Class III EXPERT RATIONALE: Class III
hemorrhagic shock involves loss of 30–40% of blood volume (1500–2000 mL),
presenting with marked hypotension, tachycardia, decreased urine output, and
altered mental status. Aggressive fluid resuscitation and blood transfusion are
required.
, QUESTION 7 Which of the following is the MOST reliable early indicator of
hemorrhagic shock?
A. Decreased blood pressure
B. Altered mental status
C. Tachycardia
D. Decreased urine output
E. Cool clammy skin
CORRECT ANSWER: C – Tachycardia EXPERT RATIONALE: Tachycardia
is the earliest and most sensitive compensatory mechanism in hemorrhagic shock.
Blood pressure may remain normal until approximately 30% of blood volume is lost
due to compensatory vasoconstriction.
QUESTION 8 A patient arrives after a fall from height. The nurse observes
paradoxical chest wall movement. This finding is MOST consistent with:
A. Tension pneumothorax
B. Hemothorax
C. Pulmonary contusion
D. Open pneumothorax
E. Flail chest
CORRECT ANSWER: E – Flail chest EXPERT RATIONALE: Flail chest
occurs when three or more consecutive ribs are fractured in two or more places,
causing a free-floating segment that moves paradoxically — inward during
inspiration and outward during expiration.
QUESTION 9 A patient with a suspected spinal cord injury at C4 is at risk for which
life-threatening complication?
