1. During the secondary survey of a trauma patient, the nurse notes tracheal deviation to the right. Which condition does this most likely indicate? → Left-sided tension pneumothorax
2. How many editions of the TNCC course have been released to date (as of the 8th edition era)? → 8
3. How does the TNCC program reinforce critical thinking in trauma care? → Through hands-on simulations and case study discussions
4. Which cervical spine injury pattern is most associated with a diving accident mechanism? → Axial compression (burst) fracture at C4-C5
5. A 3-year-old is brought in after a motor vehicle crash. Which anatomical feature makes pediatric airway management uniquely challenging compared to adults? → Proportionally larger occiput causing neck flexion when supine
6. A patient arrives after a fall from 30 feet with absent breath sounds on the right and dullness to percussion. BP is 90/60. What injury is most likely? → Massive hemothorax
7. A patient with a gunshot wound entering the left upper quadrant has a BP of 70/40 despite 2L of crystalloid. What is the most appropriate next intervention? → Immediate operative intervention (exploratory laparotomy)
8. The Trauma Nursing Process Model uses the mnemonic 'I PREPARE' for history gathering. What does the 'I' stand for? → Injuries sustained
9. Which finding on the neurovascular assessment of an injured extremity requires the MOST urgent intervention? → Absent distal pulse with pallor and paralysis
10. Obstructive shock from tension pneumothorax is BEST distinguished from other shock types by the presence of: → Absent breath sounds and tracheal deviation
11. Which of the following best describes the TNCC written exam content? → Knowledge of trauma nursing assessment, pathophysiology, and evidence-based interventions
12. Which of the following is the PRIMARY mechanism of shock in a patient with a massive pulmonary embolism? → Obstruction of right ventricular outflow causing obstructive shock
13. Which type of pelvic fracture is associated with the highest risk of life-threatening hemorrhage? → Anterior-posterior compression fracture
14. A hospital seeking verification as a Level I trauma center by the American College of Surgeons (ACS) must ensure nursing staff meet which TNCC requirement? → A defined percentage of trauma nurses must hold TNCC certification
15. How does TNCC certification benefit a nurse professionally when applying for trauma unit positions? → It signals specialized trauma competency that distinguishes the applicant
16. The Cushing's triad is a late sign of increased ICP. Which combination correctly identifies all three components? → Hypertension, bradycardia, irregular respirations
17. Which assessment finding most reliably distinguishes tension pneumothorax from simple pneumothorax? → Tracheal deviation and hemodynamic instability
18. When performing BVM ventilation in an apneic trauma patient, the recommended tidal volume is approximately: → 500-600 mL or enough to produce visible chest rise
19. What role does ethics play in Burn Management practice? → It guides professional conduct and protects stakeholders
20. Why is continuing education important in Musculoskeletal Trauma? → To stay current with evolving standards and practices
21. A patient presents with JVD, muffled heart sounds, and hypotension after a penetrating chest wound. This triad is known as: → Beck's triad
22. The 'F' in the SAMPLE history mnemonic stands for: → Last food or fluid intake
23. What is the immediate intervention for suspected tension pneumothorax in a rapidly deteriorating patient? → Needle decompression at the second intercostal space, midclavicular line
24. What preparation is recommended before attending the TNCC course? → Completing the pre-course study materials provided by ENA
25. A burn patient's urine output drops to 0.3 mL/kg/hr despite adequate fluid resuscitation. The most appropriate intervention is: → Increase IV fluid rate to achieve target output of 0.5–1 mL/kg/hr
26. When assessing circulation in the primary survey, which finding indicates Class III hemorrhagic shock? → 30–40% blood loss with hypotension, tachycardia, and confusion
27. A patient with a head injury has a PaCO2 of 55 mmHg. What is the most likely effect on cerebral blood flow? → Increased CBF due to vasodilation
28. Why is reading the question carefully important? → To avoid misinterpreting what is being asked
29. Mafenide acetate (Sulfamylon) differs from silver sulfadiazine primarily because it: → Provides broader gram-negative coverage and penetrates eschar
30. What is the relationship between theory and practice in Pediatric Trauma? → Theory provides the foundation; practice applies it to real situations
