TNCC Written Exam 2026/2027 | 300+ Practice Questions,
Correct Answers & Detailed Rationales | 9th Edition
Section 1: Trauma Nursing Process & Preparation
1. What is the primary purpose of the Trauma Nursing Process (TNP)?
A. To establish a definitive diagnosis before treatment
B. To provide a systematic approach to trauma assessment and
management
C. To replace physician assessment
D. To determine the patient's final disposition
Answer: B
Rationale: The TNP provides a systematic framework for rapidly
identifying and treating life-threatening problems while continuously
reassessing the patient.
2. What should occur before the arrival of a trauma patient?
A. Complete the secondary survey
B. Prepare the room, equipment, personnel, and PPE
C. Obtain a complete medical history
D. Perform a neurological examination
Answer: B
Rationale: Preparation is the first component of the TNP and ensures
personnel and resources are ready before patient arrival.
3. Which action is most important when receiving a prehospital
trauma notification?
A. Delay preparation until the patient arrives
B. Activate the appropriate trauma response
,C. Obtain consent for treatment
D. Begin discharge planning
Answer: B
Rationale: Early activation allows the trauma team to prepare
equipment, roles, medications, and interventions.
4. Why are assigned team roles important during trauma
resuscitation?
A. They eliminate the need for communication
B. They reduce duplication and improve coordination
C. They allow one person to perform all interventions
D. They prevent reassessment
Answer: B
Rationale: Clearly defined roles improve teamwork and reduce delays
and duplication.
5. Which PPE consideration is especially important during trauma
resuscitation?
A. Infection and body-fluid exposure
B. Patient comfort only
C. Noise reduction
D. Medication identification
Answer: A
Rationale: Trauma care frequently involves blood and other body fluids,
requiring appropriate protection.
6. What does mechanism of injury (MOI) help the trauma nurse
determine?
A. The patient's insurance status
B. Potential patterns of injury
,C. The patient's discharge date
D. The exact diagnosis
Answer: B
Rationale: Understanding the mechanism helps the team anticipate
possible injuries and prioritize assessment.
7. A patient involved in a high-energy collision should be assessed
based primarily on:
A. Mechanism alone
B. Clinical findings and mechanism together
C. Age alone
D. Pain score alone
Answer: B
Rationale: MOI helps guide suspicion, but clinical assessment
determines immediate priorities.
8. Which finding requires immediate attention during the initial
impression?
A. Mild ankle pain
B. Uncontrolled external hemorrhage
C. Small superficial abrasion
D. Chronic back pain
Answer: B
Rationale: Uncontrolled life-threatening hemorrhage can rapidly cause
death and requires immediate intervention.
9. Which change may cause the trauma team to use a C-ABC
approach?
A. Mild nausea
B. Catastrophic external bleeding
, C. Stable blood pressure
D. Minor extremity bruising
Answer: B
Rationale: Catastrophic hemorrhage takes priority before airway
assessment when immediately life-threatening.
10. What is the purpose of the initial impression?
A. To establish the final diagnosis
B. To rapidly identify immediately life-threatening problems
C. To complete the entire physical examination
D. To determine insurance coverage
Answer: B
Rationale: The initial impression provides a rapid overview and
identifies conditions requiring immediate intervention.
11. Which patient should generally receive the highest priority?
A. Stable patient with an isolated finger fracture
B. Patient with uncontrolled hemorrhage
C. Patient with mild headache
D. Patient with a superficial abrasion
Answer: B
Rationale: Uncontrolled hemorrhage is an immediate threat to life.
12. Which principle is central to trauma care?
A. Complete diagnosis must precede treatment
B. Life threats are treated as they are identified
C. Secondary survey always comes first
D. Pain management must wait until discharge
Answer: B
