Section 1: Critical Thinking and Trauma Care Principles
(PHTLS Philosophy, Golden Period, and Clinical Decision-Making)
Q1: According to the PHTLS 10th Edition philosophy, what is the foundational belief regarding trauma
patient care?
A. A. Only Level I trauma centers should manage trauma patients
B. B. All trauma patients deserve the best possible care, and every practitioner has a duty to apply
critical thinking to optimize outcomes [CORRECT]
C. C. Prehospital care should focus solely on rapid transport without intervention
D. D. Critical thinking is only necessary for complex multi-system trauma
Correct Answer: B
Rationale: The PHTLS philosophy states that all trauma patients deserve the best possible care and that every practitioner
has a duty to apply critical thinking to optimize patient outcomes. This principle underpins all PHTLS education and
guides clinical decision-making in the prehospital environment.
Q2: Which of the following best describes the critical thinking process as defined in PHTLS 10th Edition?
A. A. A static protocol-based approach to patient assessment
B. B. A dynamic process of developing a plan, initiating it, reassessing, and adjusting as the patient
condition or circumstances change [CORRECT]
C. C. A linear algorithm that must be followed in exact sequence without deviation
D. D. An intuitive approach that relies solely on provider experience without systematic reassessment
Correct Answer: B
Rationale: PHTLS defines critical thinking as a dynamic process requiring the provider to develop a plan of action, initiate
the plan, reassess the plan as care moves forward, and adjust the plan as the patient condition or circumstances change.
This continuous cycle of assessment and adaptation is central to effective trauma care.
Q3: A prehospital provider wants to use a non-evidence-based wound dressing because they have always used
it. According to PHTLS principles, which statement is correct?
A. A. Preferences override principles when the provider has extensive experience
B. B. Principles define the duties required to optimize patient survival and outcomes; preferences do
not override evidence-based principles [CORRECT]
C. C. Individual preferences take priority in the field when protocols are unclear
D. D. Both principles and preferences carry equal weight in clinical decision-making
Correct Answer: B
Rationale: The science of medicine provides the principles of medical care. Principles define the duties required of the
prehospital care practitioner in optimizing patient survival and outcome. Preferences are individual choices that do not
override evidence-based principles, regardless of provider experience or personal habit.
Q4: The Golden Period in trauma care refers to which time interval?
A. A. The first 60 minutes from injury to hospital arrival
B. B. The time from injury to arrival at the appropriate site for definitive care [CORRECT]
C. C. The first 24 hours of in-hospital trauma resuscitation
D. D. The period during which tourniquets can be safely applied before ischemic damage
Correct Answer: B
Rationale: The Golden Period is defined as the time from injury to arrival at the appropriate site for definitive care, which
is critical to patient survival. One of the most important responsibilities of a prehospital care practitioner is to minimize
on-scene time and expedite both field care and transport.

Q5: What is the Platinum Ten Minutes as described in PHTLS 10th Edition?
A. A. The maximum time allowed for on-scene spinal immobilization procedures
B. B. The first 10 minutes after injury during which prehospital providers should minimize on-scene
time for optimal patient outcome [CORRECT]
C. C. The time window during which IV fluid resuscitation must be initiated
D. D. The recommended interval between primary and secondary surveys
Correct Answer: B
Rationale: The Platinum Ten Minutes concept states that the first 10 minutes after injury are critical for patient outcome,
and prehospital providers should aim to minimize on-scene time during this period. This complements the Golden Period
concept by emphasizing early intervention and rapid transport.
Q6: Evidence-based practice in PHTLS is best described as the integration of which three components?
A. A. Protocol adherence, provider experience, and patient transport time
B. B. Best available evidence, clinical expertise, and patient values [CORRECT]
C. C. Hospital guidelines, field experience, and equipment availability
D. D. Medical direction, crew familiarity, and resource allocation
Correct Answer: B
Rationale: Evidence-based practice integrates the best available research evidence, the clinical expertise of the
practitioner, and the values and preferences of the patient. This three-part framework ensures that prehospital trauma care
is both scientifically grounded and patient-centered.
Q7: A Level I trauma center is best described as which of the following?
A. A. A facility that provides initial stabilization only before transfer
B. B. A comprehensive trauma facility capable of providing total care for every aspect of injury from
prevention through rehabilitation [CORRECT]
C. C. A community hospital with basic surgical capabilities
D. D. A facility that specializes exclusively in burn injuries and rehabilitation
Correct Answer: B
Rationale: A Level I trauma center is a comprehensive facility capable of providing total care for every aspect of injury,
from prevention through rehabilitation. These centers have 24-hour in-house coverage by general surgeons and prompt
availability of specialists in orthopedics, neurosurgery, and other disciplines.
Q8: When determining transport destination for a trauma patient, which factor should be the PRIMARY
consideration according to PHTLS?
A. A. The closest hospital regardless of capability
B. B. The most appropriate facility for the patient's specific injuries (appropriate site for definitive
care) [CORRECT]
C. C. The hospital preferred by the patient's family members
D. D. The hospital with the shortest emergency department wait time
Correct Answer: B
Rationale: The primary consideration in transport destination is getting the patient to the most appropriate facility for their
specific injuries. The Golden Period emphasizes that the time from injury to arrival at the appropriate site for definitive
care is critical to survival, not just reaching the closest facility.
Q9: A paramedic arrives at a motor vehicle crash scene and immediately begins spinal immobilization without
assessing scene safety first. What PHTLS principle has been violated?
A. A. The Golden Period principle
