Section 1: Scene Safety & Assessment (XABCDE Framework) (Q1-
10)
Q1. According to the PHTLS 8th Edition XABCDE framework, what does the "X" stand
for and why is it prioritized first?
A. X-ray imaging to identify injuries
B. Exsanguination (massive hemorrhage) control as the first priority before airway
C. Exposure to assess for additional injuries
D. Examination of the extremities
Rationale: The XABCDE framework places exsanguination (massive external
hemorrhage) as the first priority, recognizing that uncontrolled bleeding is the most
common cause of preventable death in trauma. Airway comes after life-threatening
bleeding is addressed. X-ray, exposure, and extremity examination are not the "X"
priority.
Correct Answer: B
Q2. During scene size-up, a 32-year-old male was involved in a high-speed MVC with
significant front-end damage. He is ambulatory at the scene. Which mechanism of injury
finding most strongly indicates the need for transport to a trauma center?
A. Minor scratches on the arms
B. Intrusion of greater than 12 inches into the occupant compartment
C. Deployment of airbags only
D. Patient self-extricated without difficulty
Rationale: Significant intrusion (>12 inches into occupant compartment, or >18 inches
anywhere) is a CDC Field Triage Decision Scheme criterion for transport to a trauma
center. It indicates high-energy transfer and potential for serious internal injuries.
,Airbag deployment alone and self-extrication are not high-risk criteria.
Correct Answer: B
Q3. A patient involved in a motorcycle crash was thrown 20 feet from the bike. Using
the PHTLS kinetic energy principles, which statement best describes the energy
transfer?
A. Energy transfer is minimal because the patient was thrown clear
B. Energy transfer was significant because the patient was thrown, indicating high-
energy mechanism
C. Energy transfer only occurs if the patient strikes the ground
D. The helmet absorbed all energy
Rationale: Being thrown from a motorcycle (or any vehicle) indicates a high-energy
mechanism because the patient's body had to absorb enough kinetic energy to be
ejected. The distance thrown correlates with energy transfer. Helmets protect against
head injury but do not prevent energy transfer to the body.
Correct Answer: B
Q4. What is the primary purpose of the "D" (Disability) component in the XABCDE
assessment?
A. To determine the patient's insurance status
B. To rapidly assess neurologic function using AVPU and pupillary response
C. To perform a detailed neuro exam
D. To check for spinal fractures
Rationale: The disability assessment in XABCDE is a rapid screen for neurologic
function, typically using AVPU (Alert, Voice, Pain, Unresponsive) and pupillary response.
It is not a detailed neuro exam (performed later) and does not address insurance or
isolated spinal assessment.
Correct Answer: B
, Q5. A trauma patient is found lying in a snowbank at night. After addressing
exsanguination, airway, and breathing, what is the next priority regarding
environmental management?
A. Complete the secondary survey first
B. Remove all clothing to assess for injuries, then cover with warm blankets
C. Prevent hypothermia by minimizing exposure time and using active warming
measures
D. Move the patient to the ambulance before any exposure
Rationale: The "E" in XABCDE includes exposure (removing clothing to assess for
injuries) AND environmental control (preventing hypothermia). In cold environments,
exposure time should be minimized and active warming measures used. Hypothermia
worsens coagulopathy and increases mortality in trauma patients.
Correct Answer: C
Q6. Which of the following is NOT a component of the CDC Field Triage Decision Scheme
(Step One - Physiologic Criteria)?
A. Glasgow Coma Scale <14
B. Systolic blood pressure <90 mmHg
C. Respiratory rate <10 or >29 breaths per minute
D. Heart rate >120 bpm
Rationale: Step One physiologic criteria include: GCS <14, SBP <90 mmHg, and RR <10
or >29 (or need for ventilatory support). Heart rate is not a Step One criterion, though
tachycardia is an important sign of shock. These vital sign thresholds identify patients
who need trauma center care.
Correct Answer: D
Q7. A patient has a GCS score of 8 (E2, V2, M4). Which description matches this finding?
