TRAUMA QUESTIONS WITH ANSWERS &
RATIONALES | AMERICAN COLLEGE OF
SURGEONS (ACS) ATLS PREP
1. In the ATLS 11th Edition approach, what does the “x” in xABCDE emphasize?
A. Evaluation of cervical spine injury
B. Control of life-threatening external hemorrhage
C. Assessment of neurologic disability
D. Evaluation of abdominal trauma
Answer: B. Control of life-threatening external hemorrhage
Rationale: ATLS 11 refined the traditional ABCDE sequence to xABCDE. The “x”
emphasizes the rapid recognition and control of exsanguinating external hemorrhage when
present, because uncontrolled hemorrhage can cause rapid death.
2. A trauma patient arrives with massive bleeding from a lower-extremity wound. What
should be prioritized?
A. Obtain a CT scan
B. Complete the secondary survey
C. Control the external hemorrhage
D. Obtain a detailed medical history
Answer: C. Control the external hemorrhage
Rationale: Life-threatening external hemorrhage should be addressed immediately during the
“x” component of the primary survey. Definitive imaging and detailed history should not
delay hemorrhage control.
3. Which sequence represents the ATLS 11th Edition primary survey framework?
A. ABCDE
B. CABDE
C. xABCDE
D. BACDE
Answer: C. xABCDE
Rationale: ATLS 11 incorporates the “x” before ABCDE to highlight the importance of
rapidly identifying and controlling life-threatening external hemorrhage.
,4. Which finding most strongly indicates the need for immediate airway intervention in
a trauma patient?
A. Mild facial bruising
B. Ability to speak normally
C. Inability to maintain airway patency
D. Isolated closed forearm fracture
Answer: C. Inability to maintain airway patency
Rationale: Airway assessment and management are immediate priorities after addressing
exsanguinating external hemorrhage. Failure to maintain a patent airway requires prompt
intervention.
5. A patient with blunt chest trauma develops severe respiratory distress, hypotension,
and markedly decreased breath sounds on one side. Which condition should be
suspected?
A. Simple rib fracture
B. Tension pneumothorax
C. Pulmonary contusion only
D. Isolated clavicular fracture
Answer: B. Tension pneumothorax
Rationale: Severe respiratory compromise with hypotension and unilateral markedly
decreased breath sounds is highly concerning for tension pneumothorax, a life-threatening
condition requiring immediate treatment.
6. What is the principal objective of the primary survey?
A. Establish a complete diagnosis of every injury
B. Identify and immediately treat life-threatening conditions
C. Obtain a complete psychosocial history
D. Complete all definitive imaging studies
Answer: B. Identify and immediately treat life-threatening conditions
Rationale: The primary survey is designed to rapidly identify and manage immediately life-
threatening problems. A more detailed assessment follows once immediate threats are
addressed.
7. Which intervention is appropriate for a hemodynamically unstable trauma patient
with suspected pelvic-ring disruption?
A. Delay treatment until CT is completed
B. Apply an external pelvic compression device
C. Encourage the patient to walk
D. Perform a routine outpatient radiographic examination
, Answer: B. Apply an external pelvic compression device
*Rationale: Pelvic compression can help reduce pelvic volume and control hemorrhage
associated with unstable pelvic injury. ATLS 11 includes pelvic hemorrhage control among
its practical trauma-management skills. *
8. Which assessment is specifically used to evaluate neurologic status during the
primary survey?
A. Glasgow Coma Scale
B. Serum sodium alone
C. Abdominal ultrasound
D. Pelvic radiography
Answer: A. Glasgow Coma Scale
Rationale: The Glasgow Coma Scale is an important component of neurologic assessment
during the disability portion of the primary survey.
9. Why is prevention of hypothermia important in severely injured patients?
A. Hypothermia always improves coagulation
B. Hypothermia can contribute to physiologic deterioration
C. Hypothermia eliminates the need for transfusion
D. Hypothermia prevents all neurologic injury
Answer: B. Hypothermia can contribute to physiologic deterioration
Rationale: Trauma patients are vulnerable to heat loss. Preventing and treating hypothermia
is an important component of trauma resuscitation and exposure management.
10. Which of the following is an appropriate component of the secondary survey?
A. Complete history and detailed head-to-toe examination
B. Ignoring the primary survey findings
C. Delaying treatment of active hemorrhage
D. Performing elective procedures before stabilization
Answer: A. Complete history and detailed head-to-toe examination
Rationale: The secondary survey is performed after immediate life threats have been
identified and addressed. It involves a systematic history and comprehensive physical
examination.
11. A trauma patient remains hypotensive despite initial resuscitative measures. What
should the trauma team continually reassess?
A. Only the patient's temperature
B. Response to resuscitation and possible ongoing hemorrhage
