TNCC 9th Edition Exam Prep (2026)
| Verified Questions, Answers &
Rationales
Ace your Trauma Nursing Core Course (TNCC) 9th Edition Exam with
confidence! This comprehensive study resource is meticulously designed to
help emergency and trauma nurses master critical trauma care concepts
and pass the final assessment on the first attempt.
Whether you are preparing for initial certification or renewing your
credentials, this guide provides a clear, structured blueprint of the core
competencies tested in the 2026 curriculum.
What’s Included:
• Authentic Practice Questions: High-yield questions mirroring the
structure, style, and complexity of the actual TNCC 9th Edition exam.
• Verified Accurate Answers: Save time cross-referencing materials
with direct, precise answers for rapid review.
• Comprehensive Rationales: In-depth explanations for both correct
and incorrect options to solidify your clinical judgment and
understanding of the Trauma Nursing Process (TNP).
Core Topics Covered:
• The Trauma Nursing Process (A–I Assessment)
• Airway, Ventilation, and Shock Management
• Thoracic, Abdominal, and Maxillofacial Trauma
• Brain, Craniofacial, and Spinal Cord Injuries
• Special Populations (Pediatric, Geriatric, and Bariatric Trauma)
• Disaster Management and Psychosocial Aspects of Trauma Care
1. Which intervention is recommended regarding the use of drug-
assisted intubation and rapid sequence intubation?
1
, •
• Answer: Pre-oxygenate to prolong the time to hypoxia
• Rationale: Pre-oxygenation replaces the nitrogen nitrogen-oxygen mixture in the
patient's functional residual capacity with 100% oxygen. This creates an "oxygen
reservoir" that delays the onset of oxygen desaturation and hypoxia during the apneic
phase of rapid sequence intubation (RSI), maximizing the safe apnea time for the
clinician to secure the airway.
•
2. Which normal anatomic or physiologic change in an older adult place
them at a higher risk for aspiration?
•
• Answer: Relaxed muscles of the oropharynx
• Rationale: Aging is associated with progressive sarcopenia and loss of muscle tone
throughout the body, including the oropharyngeal and esophageal musculature. This
relaxation impairs the swallowing reflex, delays upper esophageal sphincter opening, and
decreases the effectiveness of protective airway reflexes (like coughing), significantly
increasing the risk of aspiration.
•
3. A patient has been diagnosed with an incomplete spinal cord injury at
L1. Which finding would indicate sacral sparing?
•
• Answer: Voluntary anal sphincter tone
• Rationale: Sacral sparing refers to the preservation of motor or sensory function at the
lowest sacral segments (S4–S5) after an incomplete spinal cord injury. Finding voluntary
contraction of the anal sphincter or intact perianal sensation proves that the long tracts of
the spinal cord are partially intact, which carries a much better prognosis for neurological
recovery.
•
4. An adult patient weighing 75 kg sustained partial and full thickness
burns to 32% of their body 2 hours prior to arrival. Intravenous fluid
resuscitation was calculated to be 400 mL/hour. The urine output over
the last hour was 15mL. What intervention should the nurse anticipate?
2
, •
• Answer: Increase isotonic crystalloid infusion rate
• Rationale: In an adult burn patient, standard fluid resuscitation aims to maintain a target
urine output of 0.5 to 1.0 mL/kg/hour (which would be roughly 37.5–75 mL/hour for a 75
kg patient). A urine output of 15 mL indicates inadequate organ perfusion and under-
resuscitation, necessitating an upward adjustment of the isotonic crystalloid (e.g.,
Lactated Ringer's) infusion rate.
•
5. A patient is diagnosed with a T12 spinal cord injury following a 20-
foot fall. Which finding is consistent with spinal shock?
•
• Answer: Loss of reflexes
• Rationale: Spinal shock is a temporary physiological response that occurs immediately
following a traumatic spinal cord injury. It is characterized by the temporary loss of all
reflex, motor, and sensory function below the level of the injury. Flaccid paralysis and
absent deep tendon reflexes are hallmark signs.
•
6. A patient is brought to the emergency department following a motor
vehicle rollover and is complaining of left upper abdominal pain and left
shoulder pain. This presentation is most consistent with an injury to
which organ?
•
• Answer: Spleen
• Rationale: Left upper quadrant pain following blunt abdominal trauma strongly points to
a splenic injury. The accompanying left shoulder pain is known as Kehr’s sign, a classic
example of referred pain caused by diaphragmatic irritation from free blood pooling in
the peritoneal cavity.
•
7. An adult patient is brought to the emergency department following a
motor vehicle collision with complaints of neck pain. They have
identified as a person in the process of transitioning from male to female.
What effect of hormone therapy should be considered when planning
care for this patient?
