ATLS 11TH EDITION POST-TEST 2026
PRACTICE EXAMINATION COMPLETE (100)
CURRENT TESTING QUESTIONS AND
CORRECT ANSWERS WITH DETAILED
EXPLANATIONS|GUARANTEED PASS.
ATLS
Prepare with confidence using this ATLS 11th Edition Post-Test
Practice Examination, designed to assess advanced trauma life
support knowledge and clinical decision-making skills. It focuses on
primary and secondary trauma surveys, airway management,
hemorrhage control, shock recognition, resuscitation strategies, and
injury-specific interventions. The exam strengthens critical thinking
and rapid response abilities in emergency trauma care. Suitable for
healthcare professionals and providers completing ATLS 11th Edition
training and certification preparation.
MULTIPLE CHOICE.
Subsection 1: Primary Survey & xABCDE (Questions 1–10)
1. What is the correct sequence of the ATLS 11th Edition
primary survey?
A. A-B-C-D-E
B. C-A-B-D-E
, Page 2 of 50
C. x-A-B-C-D-E
D. B-A-C-D-E
Answer: C. x-A-B-C-D-E
Explanation: The 11th Edition introduces the letter “x” to
represent control of exsanguinating external hemorrhage. This
is now prioritized before the traditional A (Airway with cervical
spine protection) because uncontrolled external hemorrhage is
the most preventable cause of early trauma death. The
sequence is now x-ABCDE (eXsanguination, Airway, Breathing,
Circulation, Disability, Exposure).
2. Which of the following is the ONLY new letter added to the
primary survey in the 11th Edition?
A. Z (zero-degree Celsius blood storage)
B. x (exsanguinating hemorrhage)
C. W (wound packing)
D. G (Glasgow Coma Scale reassessment)
Answer: B. x (exsanguinating hemorrhage)
Explanation: According to the ACS Brief (September 16, 2025),
“For certain patients, rapid control of exsanguinating external
hemorrhage is lifesaving.” The letter “x” is now placed before the
traditional ABCDE sequence to emphasize this critical first step.
3. A 29-year-old male arrives with a stab wound to the left
chest with bright red blood spurting from the wound. What is
your FIRST action?
, Page 3 of 50
A. Open the airway
B. Direct pressure + occlusive seal
C. Intubate the patient
D. Administer 1 L of Lactated Ringer’s solution
Answer: B. Direct pressure + occlusive seal
Explanation: In the x-ABCDE algorithm, control of life-
threatening external hemorrhage takes priority over airway and
breathing. Direct pressure should be applied immediately,
followed by an occlusive seal to prevent air entry and potential
tension pneumothorax.
4. 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
Explanation: A definitive airway is a cuffed tube placed in the
trachea, secured in place, and connected to oxygen-enriched
ventilation. Oropharyngeal and nasopharyngeal airways are
adjuncts, not definitive. Bag-valve-mask ventilation is a
temporizing measure.
5. What is the minimum acceptable systolic blood pressure
in an adult trauma patient?
A. 80 mmHg
B. 90 mmHg
, Page 4 of 50
C. 100 mmHg
D. 110 mmHg
Answer: B. 90 mmHg
Explanation: Systolic BP <90 mmHg defines hypotension in
adult trauma patients and requires immediate intervention.
6. In the 11th Edition communication model, the structured
handover format is S-xABCDE-BAR. What does “S” stand for?
A. Safety
B. Situation
C. Site
D. Symptoms
Answer: B. Situation
Explanation: The S-xABCDE-BAR model ensures structured and
safe case handover: Situation, xABCDE, Background,
Assessment, Recommendation.
7. TCA (trauma center arrival) less than 10 minutes, torso
GSW → what is the operating room step #1?
A. CPR → epinephrine
B. Bilateral finger thoracostomy + Zone-1 REBOA
C. Pericardiocentesis
D. Laparotomy
Answer: B. Bilateral finger thoracostomy + Zone-1 REBOA
Explanation: The new ATLS 11 trauma center arrival (TCA)
algorithm prioritizes rapid decompression of tension
