Trauma Nursing Core Course Certification Exam (Version
2)– Emergency Trauma Nursing Assessment (TNCC EXAM)
Updated and Latest Questions and Correct Answers with
Rationale
1. What is the priority intervention for a trauma patient presenting with catastrophic
external hemorrhage?
A. Perform a jaw-thrust maneuver to secure the airway
B. Establish two large-bore intravenous lines
C. Administer high-flow oxygen via a non-rebreather mask
D. Apply direct pressure or a tourniquet to the bleeding site
Ans: D
Rationale: In trauma care, the sequence of assessment often follows the C-ABCDE approach when
massive hemorrhage is present. Life-threatening bleeding can lead to exsanguination much faster than an
airway obstruction can cause death. Direct pressure is the first line of defense for controlling external
bleeding in an extremity. If direct pressure is insufficient, a tourniquet should be applied immediately to
stop the blood loss. This intervention is part of the circulation component but takes precedence in ‘C-ABC’
scenarios. After the bleeding is controlled, the nurse must then proceed to assess the airway and
breathing. Failure to stop catastrophic bleeding renders later resuscitation efforts, like fluid replacement,
largely ineffective. Addressing the source of blood loss early increases the patient’s chances of survival
significantly.
,2. Which physical finding is most indicative of a tension pneumothorax?
A. Muffled heart sounds and hypertension
B. Bilateral breath sounds and crackles
C. Paradoxical chest wall movement
D. Tracheal deviation and absent breath sounds on one side
Ans: D
Rationale: A tension pneumothorax is a life-threatening condition where air enters the pleural space but
cannot escape. This leads to increased intrapleural pressure, which compresses the lung and shifts the
mediastinum. Tracheal deviation is a late but classic sign indicating a significant mediastinal shift away
from the affected side. Absent or significantly diminished breath sounds on the side of the injury are
common indicators. Patients often display severe respiratory distress and signs of obstructive shock due
to decreased venous return. Immediate needle decompression is required to relieve the pressure before
it causes cardiovascular collapse. Monitoring for these specific physical signs allows for rapid
intervention in the primary survey. Understanding the pathophysiology helps the nurse distinguish this
from a simple pneumothorax or hemothorax.
,3. What is the primary goal of the ‘E’ component in the primary survey?
A. Ensure the patient is fully exposed while preventing hypothermia
B. Evaluate the patient’s neurological status using GCS
C. Establish a definitive airway for ventilation
D. Examine the posterior surfaces for hidden injuries
Ans: A
Rationale: The ‘E’ in the A-B-C-D-E primary survey stands for Exposure and Environmental Control. It is
essential to remove all clothing to identify every possible injury the patient may have sustained.
However, removing clothing places the patient at a high risk for developing hypothermia. Hypothermia is
a part of the ‘lethal triad’ in trauma, alongside acidosis and coagulopathy. Therefore, the nurse must use
warm blankets and increase the room temperature once the assessment is done. Keeping the patient
warm helps maintain normal coagulation and metabolic processes. The nurse must balance the need for a
thorough physical exam with the need for heat retention. This step is critical for preventing secondary
complications that can worsen the patient’s prognosis.
, 4. When assessing the ‘D’ (Disability) in the primary survey, which assessment tool is most
commonly utilized?
A. The Visual Analog Scale (VAS)
B. The Revised Trauma Score (RTS)
C. The Glasgow Coma Scale (GCS)
D. The Apgar Score
Ans: C
Rationale: The ‘D’ component focuses on the patient’s neurological status and level of consciousness. The
Glasgow Coma Scale is the standard tool used to objectively measure eye opening, verbal response, and
motor response. A lower score on the GCS indicates a more severe impairment of brain function. This
assessment helps identify potential intracranial injuries or the need for airway protection if the score is 8
or less. The nurse also checks pupil size and reactivity to light during this phase. Assessing for gross
motor movement in all extremities provides additional data on spinal cord integrity. Rapidly identifying
neurological deficits allows for early neurosurgical consultation or imaging. Consistent monitoring of the
GCS is vital for detecting subtle changes in the patient’s condition over time.
