Section 1: Primary Survey & xABCDE
Questions 1–50
1. What is the correct sequence of the ATLS 11th Edition
primary survey?
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 “x” to represent control of
exsanguinating external hemorrhage, which takes priority over the
traditional A (airway with cervical spine protection). The sequence
is x-ABCDE (eXsanguination, Airway, Breathing, Circulation,
Disability, Exposure).
,2. A patient arrives with a gunshot wound to the right thigh
and an arterial fountain of blood. Your first action should be:
a) Jaw thrust
b) Tourniquet 2–3 inches proximal to the wound
c) Intubate
d) 1 liter of Lactated Ringer's solution
Answer: b) 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 above the wound to
stop the bleeding.
3. Which of the following is a definitive airway?
a) Oropharyngeal airway
b) Nasopharyngeal airway
c) Endotracheal tube with cuff inflated
d) Bag-valve-mask ventilation
Answer: c) Endotracheal tube with cuff inflated
Rationale: A definitive airway is a cuffed tube placed in the
trachea, secured, and connected to oxygen-enriched ventilation.
Oropharyngeal and nasopharyngeal airways are adjuncts, not
definitive airways.
,4. In the x-ABCDE approach, what does the “x” specifically
represent?
a) X-ray
b) Exsanguinating hemorrhage
c) Extremity injury
d) Exposure
Answer: b) Exsanguinating hemorrhage
Rationale: “x” stands for exsanguinating hemorrhage. The priority
is to stop life-threatening external bleeding before proceeding to
the standard ABCDE survey.
5. According to the 11th Edition, which of the following is a
trigger to repeat the full xABCDE survey?
a) Drop in blood pressure or oxygen saturation
b) Change in GCS or pupils
c) New bleeding or swelling
d) All of the above
Answer: d) All of the above
Rationale: The primary survey is not a one-time event. Signs to
trigger a repeat full xABCDE include a drop in BP or SpO₂, change
in GCS or pupils, or new bleeding/swelling.
, 6. The ONLY new letter in the 11th-edition primary survey is:
a) Z for Zone-1 REBOA
b) x for exsanguinating hemorrhage
c) W for whole blood
d) G for glucose check
Answer: b) x for exsanguinating hemorrhage
Rationale: The primary survey is now xABCDE, with “x”
representing rapid control of exsanguinating external
hemorrhage.
7. A patient with a stab wound to the left chest has blood
spurting from the wound. What is the FIRST action?
a) Open the airway
b) Direct pressure + occlusive seal
c) Intubate the patient
d) Administer 1 Liter of Lactated Ringer’s
Answer: b) Direct pressure + occlusive seal
Rationale: According to the 11th edition’s xABCDE algorithm,
controlling exsanguinating external hemorrhage is the number-
one priority, even before assessing the airway.
8. A patient with a GCS of 14 and a large scalp laceration has
blood pooling in the oropharynx. What is the priority action?
a) Apply oxygen via non-rebreather mask
b) Suction the oropharynx
