Advanced Trauma Life
Support (ATLS) 11th Edition
with Questions and straight
correct answers
Mission: is document checks
core principles from the American
College of Surgeons Committee
on Trauma (ACS COT) manual,
standard trauma protocols, and
critical care management
guidelines.
150 practice questions designed to reflect the scope and rigorous clinical standards of the
current ATLS 11th Edition curriculum.
Part 1: Initial Assessment, Preparation, and
Triage (Q1–Q30)
1. Q: What does the mnemonic ABCDE stand for in the initial assessment
of a trauma patient?
A: Airway with simultaneous cervical spine protection, Breathing,
Circulation with hemorrhage control, Disability (neurologic status), and
Exposure/Environment.
,2. Q: What is the primary objective of the primary survey in ATLS?
A: To identify and immediately treat life-threatening conditions.
3. Q: In the 11th edition of ATLS, what intervention has been elevated
and integrated into the "C" step alongside conventional hemorrhage
control?
A: Early identification and control of catastrophic external hemorrhage
prior to addressing the airway (shifting traditional ABC to C- ABCin
massive bleeding scenarios).
4. Q: What is the normal physiological response to acute blood loss
categorized as Class I hemorrhage (up to 15% blood volume loss)?
A: Minimal physiological changes; heart rate is normal or minimally
elevated, and blood pressure is unchanged.
5. Q: At what blood loss percentage (Class III hemorrhage) do signs of
inadequate perfusion (such as tachycardia, tachypnea, and confusion)
typically become clinically apparent?
A: 30% to 40% of total blood volume.
6. Q: What is the immediate life threat associated with a tension
pneumothorax?
A: Compression of mediastinal structures leading to decreased venous
return, obstructive shock, and cardiovascular collapse.
7. Q: What are the classic clinical signs of a tension pneumothorax?
A: Absent breath sounds, hyperresonance to percussion, tracheal
deviation away from the affected side, respiratory distress, and
hemodynamic instability.
8. Q: What is the immediate emergency treatment for a suspected
tension pneumothorax?
A: Immediate needle decompression (or finger thoracostomy) followed
by chest tube insertion.
9. Q: Where is the traditional landmark for emergency needle
decompression of a tension pneumothorax using the 11th edition
guidelines?
A: The 2nd intercostal space at the midclavicular line or the 4th/5th
intercostal space at the anterior/mid-axillary line.
10. Q: What is a massive hemothorax defined as in an adult?
A: Rapid accumulation of ≥ 1,500 mLof blood in the chest cavity.
11. Q: What is the immediate treatment for a massive hemothorax?
A: Insertion of a large-bore chest tube (typically 28–32 Fr) coupled with
, aggressive volume resuscitation and preparation for urgent
thoracotomy.
12. Q: What defines an open pneumothorax ("sucking chest
wound")?
A: A large defect in the chest wall that allows air to pass freely
between the pleural space and the atmosphere.
13. Q: What is the initial emergency field and trauma bay
management for an open pneumothorax?
A: Application of a sterile occlusive dressing taped on three sides to
act as a one-way valve.
14. Q: What defines flail chest?
A: Fractures of three or more adjacent ribs in two or more places,
resulting in a free-floating segment of the chest wall causing
paradoxical breathing.
15. Q: What is cardiac tamponade characterized by in trauma
(Beck's triad)?
A: Hypotension, distended neck veins, and muffled heart sounds.
16. Q: What is the preferred rapid bedside diagnostic test used to
evaluate cardiac tamponade and hemoperitoneum in the trauma bay?
A: Focused Assessment with Sonography for Trauma (FAST).
17. Q: What is the definitive treatment for cardiac tamponade?
A: Surgical decompression via pericardiocentesis or median
sternotomy / subxiphoid pericardial window.
18. Q: What is the primary physiological mechanism of obstructive
shock in tension pneumothorax and cardiac tamponade?
A: Impairment of diastolic filling and venous return to the heart.
19. Q: During the secondary survey, when does it begin?
A: Only after the primary survey is completed, life-threatening injuries
are addressed, and the patient's vital signs are stabilized.
20. Q: What does the secondary survey entail?
A: A head-to-toe evaluation of the patient, including a complete history
( AMPALE) and physical examination.
21. Q: What does the acronym AMPALE stand for in taking a trauma
history?
A: Allergies, Medications currently used, Past illnesses/Pregnancy, Last
meal, Events/Environment related to the injury.
