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 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).
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.
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: “For certain patients, rapid control of exsanguinating external hemorrhage is
lifesaving.” The primary survey is now xABCDE.
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
c) Start an IV with normal saline
d) Obtain a CT scan of the head
Answer: b) Suction the oropharynx
Rationale: The most common cause of difficult airway in trauma is blood, vomitus, or
debris in the oropharynx. Clearing the airway with suction is the priority.
9. During intubation of a trauma patient, what is the maximum time that should be spent
on a single intubation attempt?
a) 15 seconds
, 4|Page
b) 30 seconds
c) 45 seconds
d) 60 seconds
Answer: b) 30 seconds
Rationale: Intubation attempts should be limited to 30 seconds to avoid prolonged
hypoxia. Between attempts, the patient should be ventilated with bag-valve-mask to
maintain oxygen saturation >90%.
10. The 11th Edition recommends video laryngoscopy as:
a) A rescue device after failed direct laryngoscopy
b) The preferred primary intubation tool
c) Contraindicated in cervical spine injury
d) Only for pediatric patients
Answer: b) The preferred primary intubation tool
Rationale: Video laryngoscopy is now preferred as a primary intubation tool for trauma
patients, offering better visualization and first-pass success rates.
11. 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.
12. The gold standard for confirming correct endotracheal tube placement in a trauma
patient is:
a) Auscultation of bilateral breath sounds
b) End-tidal CO₂ detection (capnography)
c) Chest X-ray
d) Condensation in the tube
