ATLS 11TH EDITION POST-TEST: 200
MULTIPLE CHOICE QUESTIONS WITH
ANSWERS AND RATIONALES
---
SECTION 1: PRIMARY SURVEY & xABCDE APPROACH (Questions 1-
30)
---
Question 1
What is the correct sequence of the primary survey in the ATLS 11th
Edition?
A) A-B-C-D-E
B) C-A-B-C-D-E
C) x-A-B-C-D-E
D) B-A-C-D-E
Answer: C) x-A-B-C-D-E
,Rationale: The 11th Edition introduces the letter "x" to represent control of
exsanguinating external hemorrhage, which must be addressed before the
traditional A (Airway with cervical spine protection). The sequence is now x-
ABCDE (eXsanguination, Airway, Breathing, Circulation, Disability,
Exposure). This change reflects evidence that exsanguination kills faster
than hypoxia.

Question 2
The "x" in the xABCDE primary survey stands for:
A) X-ray examination
B) Exsanguinating hemorrhage control
C) Extremity assessment
D) eXposure
Answer: B) Exsanguinating hemorrhage control
Rationale: The "x" specifically represents control of exsanguinating external
hemorrhage. This is the only new letter added to the primary survey in the
11th Edition, emphasizing that life-threatening external bleeding must be
controlled before airway assessment.

,Question 3
A patient arrives with a gunshot wound to the right thigh with an arterial
fountain of blood. What is your FIRST action?
A) Jaw thrust to open airway
B) Apply a tourniquet 2-3 inches proximal to the wound
C) Intubate the patient
D) Administer 1 liter of Lactated Ringer's solution
Answer: B) Apply a tourniquet 2-3 inches proximal to the wound
Rationale: In the x-ABCDE algorithm, control of life-threatening external
hemorrhage takes priority over airway and breathing. A tourniquet should
be applied immediately 2-3 inches proximal to the wound to stop the
bleeding. Hemorrhage control before airway reflects that exsanguination
kills faster than hypoxia.

Question 4
The "A" in the xABCDE primary survey stands for:
A) Assessment
, B) Airway maintenance with Cervical SPINE protection
C) Airway and breathing
D) Alertness
Answer: B) Airway maintenance with Cervical SPINE protection
Rationale: The "A" represents Airway maintenance while simultaneously
protecting the cervical spine. All trauma patients should be assumed to
have a cervical spine injury until proven otherwise. This is a critical concept
in the initial assessment.
---
Question 5
What is the minimum GCS score that indicates a need for endotracheal
intubation?
A) 12
B) 8
C) 10
D) 6
Answer: B) 8
