PHTLS 10TH EDITION POST TEST
QUESTIONS AND ANSWERS 2027
1. What is the primary goal of the initial assessment in trauma patients?
A. Perform a head-to-toe physical examination
B. Obtain a complete medical history
C. Identify and treat life-threatening conditions
D. Establish definitive airway control
Answer: C
Conceptual Explanation: The primary goal of the initial assessment is to quickly identify
and manage immediate life-threatening conditions using the XABCDE approach.
2. Which of the following is the first step in the XABCDE trauma assessment sequence?
A. Airway
B. Exsanguinating hemorrhage
C. Breathing
D. Circulation
Answer: B
,Conceptual Explanation: Exsanguinating hemorrhage (X) takes precedence over airway
in the modern PHTLS protocol to control massive external bleeding first.
3. What is the most common cause of airway obstruction in an unconscious trauma patient?
A. Blood clots
B. Foreign bodies
C. Laryngeal fracture
D. The tongue
Answer: D
Conceptual Explanation: In an unconscious trauma patient, the loss of muscle tone causes
the tongue to fall back and obstruct the pharynx.
4. Which type of shock is most commonly observed in trauma patients?
A. Cardiogenic shock
B. Hypovolemic shock
C. Neurogenic shock
D. Septic shock
Answer: B
Conceptual Explanation: Hypovolemic shock, resulting from acute blood loss, is the most
common form of shock seen in trauma patients.
, 5. When is a tension pneumothorax typically diagnosed?
A. Based on clinical findings and physical examination
B. Based strictly on chest x-ray findings
C. After laboratory blood gas analysis
D. Only after cardiac arrest occurs
Answer: A
Conceptual Explanation: Tension pneumothorax is a clinical diagnosis based on signs like
respiratory distress, absent breath sounds, and hemodynamic instability.
6. What is the definitive prehospital treatment for a tension pneumothorax?
A. High-flow oxygen administration
B. Needle decompression or finger thoracostomy
C. Endotracheal intubation
D. Aggressive fluid resuscitation
Answer: B
Conceptual Explanation: Needle decompression or finger thoracostomy relieves the
pressure in the pleural space and is the life-saving prehospital treatment.
7. Which of the following findings is most indicative of increased intracranial pressure (ICP)?
A. Hypotension and tachycardia
