Advanced Trauma Life Support (ATLS)
11th Edition Test Bank: 150 Questions &
Answers (Verified Answers) With
Detailed Rationales || Complete A+
Guide
Question 1:
The ONLY new letter in the 11th Edition primary survey is:
A. Z (Zero tolerance for errors)
B. x (Exsanguinating hemorrhage)
C. W (Whole blood resuscitation)
D. G (Goal-directed therapy)
Correct Answer: B. x (Exsanguinating hemorrhage)
Rationale: The 11th Edition introduced "x" at the beginning of the primary survey to
prioritize control of life-threatening external hemorrhage before airway management.
The ACS Committee on Trauma stated: "For certain patients, rapid control of
exsanguinating external hemorrhage is lifesaving" .
Question 2:
A patient arrives with a gunshot wound to the thigh with an arterial fountain of blood
on arrival. What is the FIRST action?
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 x-ABCDE algorithm, control of life-threatening external hemorrhage
takes priority over airway and breathing. A tourniquet should be applied immediately 2-
3 inches proximal to the wound to stop the bleeding. Hemorrhage control before airway
reflects evidence that exsanguination kills faster than hypoxia .
Question 3:
The "A" in xABCDE stands for:
A. Assessment
B. Airway maintenance with Cervical SPINE protection
C. Airway and breathing
D. Alertness
Correct Answer: B. Airway maintenance with Cervical SPINE protection
Rationale: The "A" represents Airway maintenance while simultaneously protecting the
cervical spine. All trauma patients should be assumed to have a cervical spine injury until
proven otherwise .
Question 4:
In the x-ABCDE approach, what does the "D" stand for?
A. Disability (neurological status)
B. Diagnostic imaging
C. Drug administration
D. Decompression
Correct Answer: A. Disability (neurological status)
Rationale: The "D" step includes assessment of Glasgow Coma Scale (GCS), pupillary
size and reactivity, and any focal neurological deficits. This provides a baseline for
detecting changes in neurological status .
,Question 5:
The ATLS 11th Edition recommends the communication model S-xABCDE-BAR. What
does "S" stand for?
A. Safety
B. Situation
C. Site
D. Symptoms
Correct Answer: B. Situation
Rationale: The S-xABCDE-BAR model ensures structured and safe case
handover: Situation, xABCDE, Background, Assessment, Recommendation .
Question 6:
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. This ensures dynamic reassessment of the trauma patient .
Question 7:
What is the "Golden 20 Minutes" concept in the 11th Edition?
, A. The maximum time to apply a tourniquet
B. The critical time window from ED arrival to achieving hemorrhage control
C. The time limit for completing the primary survey
D. The window for administering antibiotics
Correct Answer: B. The critical time window from emergency department arrival to
achieving hemorrhage control
Rationale: The Golden 20 Minutes encompasses the critical time window from
emergency department arrival to achieving hemorrhage control, which includes time to
tourniquet application, time to administration of whole blood, and time to operating
room for definitive surgical control .
Question 8:
The "Exposure" portion of the primary survey includes:
A. Removing all clothing to examine the patient
B. Maintaining normothermia (preventing hypothermia)
C. Log roll to examine the back
D. All of the above
Correct Answer: D. All of the above
Rationale: Exposure involves completely undressing the patient, performing a log roll to
examine the back, and maintaining normothermia. Hypothermia prevention is critical in
trauma patients .
Question 9:
What is the minimum acceptable systolic blood pressure in an adult trauma patient?
A. 80 mmHg
B. 90 mmHg
