TNCC Pre-Course Study Guide Exam Questions & Answers 2026–2027 |
Trauma Nursing Core Course Practice Test & Verified Solutions
1. Why is it important to understand biomechanics as it relates to energy forces
and MOI?
A. It helps diagnose infections faster
B. It helps anticipate trauma effects on the body
C. It reduces need for imaging
D. It replaces physical assessment
Correct Answer: B
Rationale:
Understanding biomechanics allows clinicians to predict injury patterns based on energy transfer
and mechanism of injury (MOI). This improves early recognition of internal injuries. The other
options are incorrect because biomechanics does not replace assessment or imaging and is not
related to infection diagnosis.
2. What are common mechanisms of injury (MOI) that result in trauma?
A. Chemical, metabolic, infectious
B. Blunt, penetrating, blast
C. Acute, chronic, congenital
D. Thermal, electrical, radiation
Correct Answer: B
Rationale:
Blunt, penetrating, and blast injuries are the primary MOIs in trauma. The other options describe
unrelated classifications.
3. Which injury is associated with the PRIMARY phase of a blast injury?

A. Fractures from body displacement
B. Burns from heat exposure
C. Pulmonary barotrauma
D. Penetrating injuries from debris
Correct Answer: C
Rationale:
Primary blast injuries are caused by pressure waves affecting gas-filled organs (lungs, ears, GI
tract), leading to barotrauma. Secondary injuries involve debris, tertiary involve body
displacement, and quaternary involve burns.
4. Why is a systematic approach important in trauma assessment?
A. Reduces documentation time
B. Prevents need for labs
C. Identifies all injuries and improves outcomes
D. Eliminates need for reassessment
Correct Answer: C
Rationale:
A structured approach ensures no life-threatening injuries are missed and improves patient
outcomes. Trauma care requires continuous reassessment, not elimination of it.
5. What must the nurse do after any intervention during the primary survey?
A. Document only
B. Move to next patient
C. Reassess the patient
D. Call the physician
Correct Answer: C
Rationale:
Reassessment ensures the intervention was effective and identifies any changes in patient status.
Documentation and provider notification may occur, but reassessment is immediate priority.
