TNCC 9TH EDITION RENEWAL CLINICAL SCENARIO-
BASED PRACTICE QUESTIONS WITH CORRECT
RATIONALES |MOST RECENT AND A+ GUARANTEED.
INTRODUCTION
This comprehensive clinical scenario-based question bank is designed for trauma nurses
preparing for the Trauma Nursing Core Course (TNCC) 9th Edition Renewal Exam. Unlike
traditional knowledge-based questions, these clinical scenarios require you to apply the
Trauma Nursing Process (TNP), prioritize interventions, recognize subtle clinical findings,
and make critical decisions in realistic trauma situations. Each scenario is followed by
multiple-choice questions that test your ability to synthesize information, identify life-
threatening conditions, and implement evidence-based trauma care according to ENA
guidelines. This resource is intended to help candidates develop clinical reasoning skills,
identify knowledge gaps, and strengthen their preparation for the renewal certification
examination.

SECTION 1 – AIRWAY & BREATHING CLINICAL SCENARIOS
Scenario 1:
A 45-year-old male is brought to the emergency department by ambulance following a motor
vehicle collision. He was the restrained driver of a car that struck a tree at approximately 45
mph. On arrival, he is alert and oriented, but is speaking in short phrases and appears anxious.
His voice is hoarse, and he has swelling noted around his neck. SpO2 is 88% on room air. RR is
32 breaths/min, HR 110 bpm, BP 142/88 mmHg.
1. What is the priority intervention for this patient?
A) Apply a non-rebreather mask at 15 L/min
B) Prepare for immediate endotracheal intubation
C) Apply a cervical collar
D) Obtain a chest X-ray
Correct Answer: B
Rationale: The patient is exhibiting signs of impending airway compromise: hoarseness, neck
swelling, tachypnea, and anxiety. These findings suggest possible airway edema or hematoma
formation. Immediate endotracheal intubation is indicated to secure the airway before it
becomes completely obstructed. Do not wait for deterioration.
Scenario 2:
A 32-year-old female is brought to the ED after a high-speed MVC. She is intubated and being
ventilated. ETCO2 is 28 mmHg. SpO2 is 100% on 100% FiO2. HR 130 bpm, BP 88/52 mmHg.
The patient is on a backboard with a cervical collar in place. Lung sounds are diminished on the
left side. The provider orders a bolus of 1 liter of normal saline.

2. Which intervention should be performed FIRST?
A) Chest X-ray
B) Needle decompression of the left chest
C) FAST exam
D) Administer the fluid bolus as ordered
Correct Answer: B
Rationale: The patient has hypotension, tachycardia, diminished left breath sounds, and low
ETCO2 despite adequate oxygenation. The finding of diminished breath sounds with
hemodynamic instability suggests tension pneumothorax. Needle decompression (or finger
thoracostomy) should be performed immediately to relieve the tension. Do not delay for
imaging or other interventions.
Scenario 3:
A 28-year-old male presents with a gunshot wound to the right chest. He is awake and talking but
has difficulty breathing. You note a 2 cm wound on the right chest with air bubbling from the
wound. RR 36 breaths/min, SpO2 90% on room air, HR 118 bpm, BP 100/68 mmHg.
3. What is the most appropriate immediate intervention?
A) Apply an occlusive dressing taped on three sides
B) Insert a chest tube
C) Administer a fluid bolus
D) Obtain a chest X-ray
Correct Answer: A
Rationale: This is an open pneumothorax (sucking chest wound). The priority is to apply an
occlusive dressing taped on three sides (flutter valve) to prevent air from entering the chest
cavity while allowing trapped air to escape. Chest tube insertion will be needed but is not the
immediate priority.
Scenario 4:
A 55-year-old female with a history of COPD is involved in a fall from standing height. She is in
respiratory distress with use of accessory muscles. She is unable to speak in full sentences. RR
, Page 4 of 46
36 breaths/min, SpO2 88% on 2 L/min via nasal cannula, HR 118 bpm. Lung sounds reveal
distant breath sounds and diffuse wheezing. ETCO2 is 52 mmHg.
4. Which intervention is most appropriate?
A) Increase supplemental oxygen to 15 L/min via non-rebreather mask
B) Prepare for non-invasive positive pressure ventilation (BiPAP)
C) Administer albuterol nebulizer treatment
D) Prepare for endotracheal intubation
Correct Answer: D
Rationale: The patient has respiratory failure with hypercapnia (ETCO2 52 mmHg) and is
unable to protect her airway. The combination of respiratory distress, inability to speak in full
sentences, and elevated CO2 indicates the need for immediate intubation. BiPAP may be
considered in some cases, but this patient's presentation suggests the need for definitive
airway management.
Scenario 5:
A 22-year-old male is brought in after a motorcycle collision. He is combative and confused.
There is an open deformity to his left femur. He is speaking but is difficult to understand. HR
122 bpm, RR 28 breaths/min, SpO2 94% on room air, BP 102/70 mmHg. He has a large
hematoma to his forehead.
5. What is the priority intervention?
A) Apply a tourniquet to the left leg
B) Assess for a cause of confusion and combative behavior
C) Apply a cervical collar
D) Administer 2 L of normal saline
Correct Answer: B
Rationale: The patient is confused and combative, which may indicate hypoxia,
hypoperfusion, or head injury. The priority is to assess for the underlying cause of the altered
mental status. This should be done during the primary survey. While cervical spine
immobilization is important, the change in mental status requires immediate evaluation.
