Advanced Trauma Life Support (ATLS) 11th
Edition QUESTIONS AND DETAILED
SOLUTIONS JUST RELEASED.pdf

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
Rationale: The 11th Edition introduces "x" for control of exsanguinating external hemorrhage, addressed
before the traditional A (Airway with cervical spine protection) .




2. What does the "x" in the xABCDE sequence represent?
A) X-ray imaging
B) eXsanguinating hemorrhage control
C) eXtremity examination
D) eXposure
Answer: B
Rationale: "x" stands for exsanguinating hemorrhage control, prioritizing life-threatening external
bleeding before airway management .




3. A patient arrives with a gunshot wound to the right thigh and 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
Rationale: In the xABCDE algorithm, control of life-threatening external hemorrhage takes priority over
airway and breathing .




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
Rationale: The "A" represents airway maintenance while simultaneously protecting the cervical spine; all
trauma patients should be assumed to have a C-spine injury until proven otherwise .




5. What is the minimum GCS score that indicates a need for endotracheal intubation?
A) 12
B) 8
C) 10
D) 6
Answer: B
Rationale: GCS ≤8 indicates the patient cannot protect their airway and requires a definitive airway .




6. What is the maximum time for a single intubation attempt in a trauma patient?
A) 15 seconds
B) 30 seconds
C) 45 seconds
D) 60 seconds
Answer: B

,Rationale: Intubation attempts should be limited to 30 seconds to avoid prolonged hypoxia .




7. The gold standard for confirming correct endotracheal tube placement is:
A) Auscultation of bilateral breath sounds
B) End-tidal CO₂ detection (capnography)
C) Chest X-ray
D) Condensation in the tube
Answer: B
Rationale: Capnography is the gold standard for confirming endotracheal tube placement .




8. 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
Rationale: A definitive airway is a cuffed tube placed in the trachea, secured, and connected to oxygen-
enriched ventilation .




9. 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
Rationale: Controlling exsanguinating external hemorrhage is the number one priority, even before
assessing the airway .

, 10. According to ATLS 11th Edition, hypotension in an adult trauma patient is defined as systolic
BP:
A) <100 mmHg
B) <90 mmHg
C) <80 mmHg
D) <70 mmHg
Answer: B
Rationale: Systolic BP <90 mmHg defines hypotension and requires immediate intervention for
hemorrhagic shock until proven otherwise .




11. What triggers a repeat of 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
Rationale: The primary survey is not a one-time event; any deterioration in vital signs, mental status, or
new bleeding warrants reassessment .




12. The "B" in the xABCDE primary survey stands for:
A) Bleeding
B) Breathing and ventilation
C) Blood pressure
D) Brain
Answer: B
Rationale: "B" represents breathing and ventilation, including assessment for life-threatening thoracic
conditions.
