PHTLS 10th Edition Self-Test ()
Section I: Foundations, Philosophy, and Critical Thinking (Q1–Q10)
Q1. According to the PHTLS 10th Edition philosophy, what is the foundation of PHTLS?
A. Rigid adherence to protocol regardless of clinical circumstances
B. The belief that all trauma patients deserve the best possible care and that practitioners must
apply critical thinking to optimize outcomes
C. Rapid transport without any field intervention
D. Exclusive use of advanced invasive procedures
Correct Answer: B
Rationale: The PHTLS 10th Edition explicitly states that PHTLS is founded on the belief that all
trauma patients deserve the best possible care, and every practitioner has a duty to apply critical
thinking to optimize patient outcomes. PHTLS is not a rigid protocol system (A) but a framework
requiring clinical judgment. Option C incorrectly diminishes the role of field interventions, and
option D is wrong because PHTLS is designed for all prehospital providers, not just those performing
advanced procedures.
Q2. A prehospital provider prefers to apply a cervical collar before controlling severe arterial
bleeding from a leg wound. According to PHTLS principles regarding principles versus preferences,
which statement is correct?
A. Individual preferences always take priority over evidence-based principles
B. Preferences are individual choices that do not override evidence-based principles, and
exsanguinating hemorrhage must be controlled first
C. Principles and preferences carry equal weight in clinical decision-making
D. Preferences should be followed only when the provider has more than 5 years of experience
Correct Answer: B
Rationale: PHTLS 10th Edition distinguishes clearly between principles and preferences. Principles
are evidence-based duties required of prehospital practitioners. Preferences are individual choices
that do NOT override principles. In the XABCDE primary survey, eXsanguinating hemorrhage takes
precedence over airway and cervical spine concerns. Severe arterial bleeding must be controlled
immediately.

,Q3. Which statement best defines the "Platinum Ten Minutes" in PHTLS?
A. The interval between injury occurrence and arrival at a trauma center
B. The maximum recommended on-scene time for critically injured patients before transport
C. The time required for complete primary survey completion in the field
D. The response time goal from emergency dispatch to ambulance arrival
Correct Answer: B
Rationale: The "Platinum Ten Minutes" concept emphasizes that for critically injured trauma
patients, scene time should not exceed ten minutes. This principle recognizes that patients with life-
threatening injuries require rapid transport to definitive surgical care. While on-scene interventions
are important, they should not delay transport excessively. Option A describes the "Golden Period"
concept. Option C is incorrect because the primary survey is typically completed in under two
minutes. Option D describes dispatch-to-scene response times.
Q4. Which of the following best describes the critical thinking process as defined by PHTLS?
A. A linear process of following assessment algorithms from start to finish without deviation
B. A static process that relies on initial assessment findings to determine all interventions
C. A dynamic process requiring development of a plan, initiation, reassessment, and adjustment as
conditions change
D. A process that depends primarily on online medical direction for all clinical decisions
Correct Answer: C
Rationale: The PHTLS 10th Edition defines critical thinking in medicine as a dynamic process that
requires the practitioner to develop a plan of action, initiate the plan, reassess the plan as care for
the patient moves forward, and adjust the plan as the patient's condition or circumstances change. It
is neither linear (A) nor static (B), and while medical direction is important, critical thinking is an
independent practitioner skill (D).
Q5. You arrive at the scene of a motor vehicle collision 4 minutes after dispatch. The patient has
multiple injuries. According to the PHTLS concept of the Golden Period and Platinum Ten Minutes,
what is your primary responsibility regarding scene time?
A. Perform a comprehensive secondary survey on scene before transport to identify all injuries
B. Spend as little time on the scene as possible and expedite transport to the appropriate facility for
definitive care
C. Wait for law enforcement to secure the scene completely before beginning patient assessment
D. Remain on scene until all family members are contacted and informed of the patient's condition
Correct Answer: B
Rationale: The PHTLS 10th Edition emphasizes that the time from injury to definitive care is critical
for survival. One of the most important responsibilities is to spend as little time on the scene as
possible, performing only essential life-saving interventions before transport. A comprehensive
secondary survey (A) should not delay transport for critical patients. Waiting for law enforcement (C)
or contacting family (D) are not clinical priorities.

,Q6. According to PHTLS, which of the following is the primary purpose of understanding the
kinematics of trauma at a scene?
A. To determine who is at fault for the incident
B. To predict likely injury patterns based on the forces and mechanisms involved
C. To calculate scene time only
D. To determine transport destination based on distance alone
Correct Answer: B
Rationale: PHTLS teaches that analyzing kinematics—the mechanism, direction, and magnitude of
forces applied to the body—allows the provider to form an index of suspicion for specific injuries
that may not be immediately obvious. This guides a more thorough and targeted assessment.
Determining fault (A) is a legal matter, not a clinical one. Scene time calculation (C) and transport
destination based solely on distance (D) do not reflect the clinical purpose of kinematic analysis.
Q7. What does the acronym MARCH primarily help providers prioritize in PHTLS?
A. Scene documentation order
B. The sequence of critical interventions: Massive hemorrhage, Airway, Respiration, Circulation,
Hypothermia/Head injury
C. The order in which patients are triaged at a mass casualty incident only
D. Medication administration order
Correct Answer: B
Rationale: PHTLS 10th Edition emphasizes the MARCH algorithm as the priority sequence for the
primary survey, reflecting that uncontrolled hemorrhage is now recognized as the most time-critical,
preventable cause of death in trauma. MARCH stands for Massive hemorrhage, Airway, Respiration,
Circulation, Hypothermia/Head injury. This is not merely documentation (A) or medication
sequencing (D), and while applicable in mass casualty incidents, it is not limited to them (C).
Q8. A trauma system is classified based on its capability to provide definitive care. A Level I trauma
center is best described as one that:
A. Provides initial evaluation and stabilization before transferring all patients to a higher-level facility
B. Has 24-hour immediate availability of all specialties, personnel, and equipment necessary to
manage the most severely injured patients
C. Serves primarily rural communities and provides basic trauma care with limited surgical capability
D. Focuses exclusively on rehabilitation and long-term care
Correct Answer: B
Rationale: A Level I trauma center is the highest level of trauma care, with 24-hour immediate
availability of all specialties, personnel, and equipment necessary to manage the most severely
injured patients. Option A describes a Level III or IV center. Option C describes a rural or lower-level
facility. Option D describes a rehabilitation facility, not an acute trauma center.
pg. 3
, Q9. Which statement best describes the relationship between the Golden Period and the Platinum
Ten Minutes?
A. The Golden Period refers to the first 10 minutes of on-scene care, while the Platinum Ten Minutes
refers to total transport time
B. The Platinum Ten Minutes is a subset of the Golden Period that specifically emphasizes minimizing
on-scene time, because the entire period from injury to definitive care is critical for survival
C. The Golden Period and the Platinum Ten Minutes are interchangeable terms describing the same
time window
D. The Platinum Ten Minutes replaces the Golden Period concept in the 10th Edition as the primary
time-based principle
Correct Answer: B
Rationale: The Golden Period is the total time from injury to arrival at the appropriate site for
definitive care. The Platinum Ten Minutes specifically refers to the first 10 minutes after injury,
during which prehospital providers should aim to minimize on-scene interventions and expedite
transport. The Platinum Ten Minutes reinforces the Golden Period concept rather than replacing it
(D) or being interchangeable (C).
Q10. According to PHTLS 10th Edition philosophy, which statement best describes the role of critical
thinking in prehospital trauma care?
A. Critical thinking is only necessary for complex multi-system trauma patients, not for
straightforward injuries
B. Critical thinking is a dynamic process requiring the provider to assess the situation, the patient,
and available resources, then develop, initiate, and adjust a plan of action as conditions change
C. Critical thinking should be applied only after completing the primary survey and gathering all
diagnostic information
D. Critical thinking is the exclusive domain of physicians and should not influence the decisions of
prehospital care practitioners
Correct Answer: B
Rationale: The PHTLS 10th Edition defines critical thinking as a dynamic, continuous process in which
the healthcare practitioner assesses the situation, the patient, and available resources, then uses
that information to decide on and provide the best care. The plan must be initiated, reassessed, and
adjusted as the patient's condition or circumstances change. It is not reserved for physicians (D), not
limited to complex cases (A), and not deferred until after the primary survey (C).
Section II: Scene Safety, Primary Survey, and XABCDE (Q11–Q25)
Q11. What is the first step in the prehospital assessment of a trauma patient?
A. Perform the primary survey
B. Assess scene safety
C. Obtain patient history
D. Initiate transport
