Introduction
The PHTLS (Prehospital Trauma Life Support) 10th Edition examination
evaluates the knowledge, clinical reasoning, and field decision-making skills
required for emergency medical personnel managing trauma patients in the
prehospital environment. The exam assesses mastery of trauma assessment, airway
management, hemorrhage control, shock treatment, spinal and neurological injury
care, and trauma system utilization. Questions are presented in multiple-choice
format and frequently incorporate realistic emergency scenarios requiring rapid
prioritization and clinical judgment. Candidates must demonstrate the ability to
apply evidence-based trauma principles, perform structured patient assessments,
identify life-threatening conditions, and make appropriate transport and treatment
decisions under prehospital conditions.
,Section 1: Questions 1–35
1. A paramedic arrives at a motor vehicle collision scene. What is the FIRST
priority according to PHTLS principles?
A. Assess airway
B. Begin hemorrhage control
C. Determine transport destination
D. Ensure scene safety
Rationale: Scene safety must be confirmed before any patient contact to prevent
harm to rescuers and additional casualties.
2. The primary goal of the PHTLS approach to trauma care is to:
A. Provide definitive hospital treatment in the field
B. Rapidly identify and treat life-threatening conditions
C. Perform detailed physical examinations
D. Stabilize all fractures prior to transport
Rationale: PHTLS focuses on identifying and managing life-threatening injuries
quickly while minimizing on-scene time.
3. Which mechanism of injury has the highest risk of significant internal
trauma?
, A. Ground-level fall
B. Bicycle fall at low speed
C. High-speed motor vehicle collision
D. Minor sports injury
Rationale: High-energy mechanisms transfer large forces and significantly
increase risk for internal injuries.
4. During the primary survey, airway assessment occurs during which step?
A. Circulation
B. Airway with cervical spine protection
C. Disability
D. Exposure
Rationale: The first step in the ABCDE approach is airway assessment with spinal
protection.
5. Which sign indicates immediate airway compromise?
A. Tachycardia
B. Gurgling respirations
C. Minor facial bruising
D. Mild headache
