ATLS POST TEST ADVANCED TRAUMA
LIFE SUPPORT QUESTIONS WITH
VERIFIED ANSWERS
1. What is the primary goal of the initial assessment in the primary survey of a trauma
patient?
A. To obtain a detailed past medical history
B. To establish definitive surgical plans
C. To perform a complete head-to-toe physical examination
D. To identify and immediately treat life-threatening conditions
Answer: D
Conceptual Explanation: The primary survey focuses on identifying and immediately
treating life-threatening conditions using the ABCDE approach.
2. Which of the following is the most reliable method of confirming endotracheal tube
placement in a normotensive patient?
A. End-tidal CO2 detection
B. Observation of chest wall movement
C. Auscultation of breath sounds
,D. Presence of condensation in the tube
Answer: A
Conceptual Explanation: End-tidal CO2 monitoring (capnography or colorimetric devices)
is the most reliable confirmation of correct endotracheal tube placement in patients with
adequate perfusion.
3. What is the initial fluid bolus volume recommended for an adult trauma patient in
hemorrhagic shock?
A. 1000 mL of 5% Dextrose in Water
B. 10 mL/kg of Colloids
C. 1 to 2 liters of warmed isotonic crystalloid solution
D. Exact volume replacement with free water
Answer: C
Conceptual Explanation: ATLS guidelines recommend an initial restricted/judicious bolus
of 1 to 2 liters of warmed isotonic crystalloids, transitioning early to blood products.
4. Which physical finding distinguishes a tension pneumothorax from a simple
pneumothorax?
A. Absent breath sounds
B. Hemodynamic instability and tracheal deviation
C. Chest pain upon inspiration
, D. Subcutaneous emphysema
Answer: B
Conceptual Explanation: Tension pneumothorax causes physiological collapse,
hypotension, and tracheal deviation away from the affected side, requiring immediate
needle decompression.
5. What is the immediate treatment for a tension pneumothorax?
A. Chest tube insertion in the 5th intercostal space
B. Immediate intubation and mechanical ventilation
C. Emergency pericardiocentesis
D. Needle decompression in the 2nd intercostal space mid-clavicular line
Answer: D
Conceptual Explanation: Needle decompression is an immediate, life-saving intervention
performed before definitive chest tube insertion when tension pneumothorax is suspected.
6. Beck’s triad consists of which of the following signs?
A. Tachycardia, diaphoresis, and confusion
B. Hypertension, bradycardia, and irregular respirations
C. Tracheal deviation, absent breath sounds, and shock
D. Hypotension, muffled heart sounds, and distended neck veins
