ATLS 11th Edition Exam 2026/2027 – 200 Questions &
Answers with Detailed Rationales | Latest Advanced
Trauma Life Support Practice Test & Study Guide
SECTION I — INITIAL ASSESSMENT & xABCDE
1.
In ATLS 11, what is the first priority when a trauma patient has massive external
hemorrhage?
A. Obtain a complete medical history
B. Control the exsanguinating external hemorrhage
C. Perform a secondary survey
D. Obtain a chest radiograph
Answer: B
Rationale: ATLS 11 places immediate control of life-threatening external hemorrhage at the
beginning of the xABCDE approach because uncontrolled exsanguination can cause death
within minutes.
2.
,The primary purpose of the primary survey is to:
A. Establish the patient's final diagnosis
B. Identify and immediately treat life-threatening conditions
C. Complete a detailed neurologic examination
D. Obtain definitive imaging
Answer: B
Rationale: The primary survey rapidly identifies immediately life-threatening problems so
treatment can begin without waiting for a complete diagnosis.
3.
A trauma patient arrives with uncontrolled pulsatile bleeding from a thigh wound. What
should occur first?
A. Apply a tourniquet
B. Obtain a CT scan
C. Insert a urinary catheter
D. Perform a complete secondary survey
Answer: A
Rationale: A properly applied tourniquet is an immediate method of controlling life-
threatening extremity hemorrhage when direct pressure is insufficient or impractical.
4.
Which sequence best represents the ATLS 11 initial assessment framework?
,A. ABCDE
B. CABDE
C. xABCDE
D. BACDE
Answer: C
Rationale: ATLS 11 refined the traditional approach to xABCDE by adding an initial focus on
catastrophic external hemorrhage.
5.
During the primary survey, the trauma team should:
A. Correct life threats as they are identified
B. Wait until all diagnostic studies are complete
C. Complete the secondary survey before treatment
D. Obtain a detailed past medical history first
Answer: A
Rationale: ATLS emphasizes simultaneous assessment and treatment of immediately life-
threatening conditions.
6.
Which finding most strongly suggests airway obstruction?
A. Clear speech
B. Stridor
, C. Normal respiratory rate
D. Warm extremities
Answer: B
Rationale: Stridor indicates turbulent airflow through a narrowed upper airway and is an
important warning sign of airway obstruction.
7.
A patient with facial trauma has blood and vomitus obstructing the oropharynx. The
immediate priority is to:
A. Obtain a cervical CT
B. Clear the airway
C. Obtain an abdominal ultrasound
D. Start oral fluids
Answer: B
Rationale: An obstructed airway is an immediate threat to life and must be cleared before
less urgent diagnostic procedures.
8.
In a trauma patient, the airway should be assessed while:
A. Ignoring the cervical spine
B. Assuming there is no spinal injury
C. Protecting the cervical spine when indicated
D. Performing the secondary survey
