ATLS 11 Initial Assessment & xABCDE Study Guide |
Practice Questions, Answers & Detailed Rationales |
Exam Prep 2026/2027
Question 1: A patient arrives in the trauma bay with a spurting
arterial bleed from a left thigh wound. According to the ATLS 11th
Edition, what is the first priority?
A. Perform a jaw-thrust maneuver to open the airway
B. Apply direct pressure or a tourniquet to control the hemorrhage
C. Administer 1 liter of warmed crystalloid solution
D. Auscultate bilateral breath sounds
CORRECT ANSWER: B. Apply direct pressure or a tourniquet to
control the hemorrhage
Rationale: ATLS 11th Edition introduced the "x" in xABCDE to prioritize
control of exsanguinating external hemorrhage before airway management,
because exsanguination is the leading cause of preventable death in trauma
patients.
Question 2: The "x" in the ATLS 11th Edition xABCDE primary
survey stands for which of the following?
A. X-ray evaluation
B. Exsanguinating hemorrhage control
C. Extremity immobilization
D. eXposure of the patient
CORRECT ANSWER: B. Exsanguinating hemorrhage control
Rationale: The 11th Edition added "x" to represent rapid control of
catastrophic external hemorrhage, which must be addressed before airway
assessment.
Question 3: A 32-year-old male is brought in after a high-speed
motorcycle collision. He is unresponsive with snoring respirations.
After controlling any external hemorrhage, what is the next
priority?
A. Obtain a CT scan of the head
B. Establish two large-bore IVs
C. Open the airway while maintaining cervical spine protection
D. Perform a secondary survey
,CORRECT ANSWER: C. Open the airway while maintaining cervical
spine protection
Rationale: After "x" (hemorrhage control), the next step is "A" — airway
maintenance with simultaneous cervical spine protection.
Question 4: According to ATLS 11th Edition, which of the following
defines hypotension in an adult trauma patient?
A. Systolic BP < 100 mmHg
B. Systolic BP < 90 mmHg
C. Systolic BP < 80 mmHg
D. Mean arterial pressure < 65 mmHg
CORRECT ANSWER: B. Systolic BP < 90 mmHg
Rationale: Systolic blood pressure below 90 mmHg defines hypotension in
adult trauma patients and warrants immediate intervention for presumed
hemorrhagic shock.
Question 5: A patient has a GCS of 14 and a large scalp laceration
with blood pooling in the oropharynx. What is the priority action
during the airway assessment?
A. Apply high-flow oxygen via non-rebreather mask
B. Suction the oropharynx
C. Start an IV with normal saline
D. Obtain a CT scan of the head
CORRECT ANSWER: B. Suction the oropharynx
Rationale: The most common cause of a difficult airway in trauma is blood,
vomitus, or debris in the oropharynx. Clearing the airway with suction is
the immediate priority.
Question 6: 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
CORRECT ANSWER: C. x-A-B-C-D-E
,Rationale: The 11th Edition introduces "x" (exsanguinating hemorrhage
control) before the traditional ABCDE sequence.
Question 7: During intubation of a trauma patient, what is the
maximum time that should be spent on a single intubation
attempt?
A. 15 seconds
B. 30 seconds
C. 45 seconds
D. 60 seconds
CORRECT 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 above 90%.
Question 8: A patient with a gunshot wound to the right thigh has
an arterial fountain of blood. What is the first action?
A. Perform a jaw thrust to open the 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
CORRECT ANSWER: B. Apply a tourniquet 2–3 inches proximal to
the wound
Rationale: In the xABCDE algorithm, control of life-threatening external
hemorrhage takes priority over airway and breathing because
exsanguination kills faster than hypoxia.
Question 9: 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
CORRECT 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.
, Question 10: 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. Apply direct pressure and an occlusive seal
C. Intubate the patient
D. Administer 1 Liter of Lactated Ringer's
CORRECT ANSWER: B. Apply direct pressure and an 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.
Question 11: The ATLS 11th Edition recommends video
laryngoscopy as which of the following?
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
CORRECT 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.
Question 12: 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
CORRECT 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.
Question 13: What is the maximum volume of the initial crystalloid
fluid bolus recommended for an adult patient in hemorrhagic shock
according to ATLS?
