Section 1: Critical Thinking and Trauma Care Principles (Q1-Q8)
Q1: 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
[CORRECT]
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 or limited to complex cases; it is a foundational expectation of every prehospital
care practitioner at all times.
Q2: A prehospital provider prefers to apply a pelvic binder before initiating IV access in a patient with
suspected pelvic fracture and signs of shock. A colleague argues that IV access should come first. According
to PHTLS principles, which concept resolves this disagreement?
A. The provider with more years of experience should determine the sequence of interventions
B. Preferences are individual choices that do not override evidence-based principles, so the intervention
supported by the strongest evidence should take priority [CORRECT]
C. Both interventions are preferences, so either order is acceptable as long as both are performed
D. The principle of rapid transport should override both interventions, and neither should be performed
on scene
Correct Answer: B
Rationale: PHTLS distinguishes between principles and preferences. Principles define the duties required of prehospital
care practitioners in optimizing patient survival and are based on evidence-based science. Preferences are individual
choices that do not override principles. When a conflict arises, the evidence-based principle dictates the correct course of
action. Hemorrhage control (including pelvic binding for pelvic hemorrhage) is a principle-based intervention that takes
priority.
Q3: Which of the following statements best describes the relationship between the Golden Period and the
Platinum Ten Minutes in PHTLS?
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 during the first 10 minutes after injury, because the entire period from injury to definitive
care is critical for survival [CORRECT]

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, which is
critical for survival. One of the most important responsibilities is to spend as little time on the scene as possible. 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 by emphasizing the urgency of the earliest phase of care.
Q4: 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 [CORRECT]
C. Serves primarily rural communities and provides basic trauma care with limited surgical capability
D. Focuses exclusively on rehabilitation and long-term recovery of trauma patients
Correct Answer: B
Rationale: A Level I trauma center is the highest designation within the trauma system, providing comprehensive trauma
care with 24-hour immediate availability of all necessary specialties, personnel, and equipment to manage the most
severely injured patients. Levels II through IV have progressively fewer resources and capabilities. Understanding these
designations is essential for making appropriate destination decisions during triage.
Q5: What is the foundation of the PHTLS belief system regarding trauma patient care?
A. All trauma patients should be transported to the nearest hospital regardless of capability
B. Every practitioner has a duty to apply critical thinking and all trauma patients deserve the best
possible care to optimize outcomes [CORRECT]
C. Prehospital care should be limited to basic interventions with extensive on-scene treatment
D. Only patients meeting specific physiologic criteria deserve full trauma team activation
Correct Answer: B
Rationale: The foundation of PHTLS is the belief 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 philosophy underpins all PHTLS
education and drives the emphasis on evidence-based practice, rapid transport, and continuous reassessment throughout
the care continuum.
Q6: Evidence-based practice in prehospital trauma care is best defined as the integration of:
A. Clinical experience and patient preferences only
B. The latest technology and the most expensive treatment modalities available
C. Best available research evidence, clinical expertise, and patient values/needs [CORRECT]
D. Protocols established by the hospital receiving the trauma patient
Correct Answer: C
Rationale: Evidence-based practice integrates three key components: the best available research evidence, the clinical
expertise of the practitioner, and the values and needs of the individual patient. All three components are necessary; none
alone is sufficient. This approach ensures that prehospital care is both scientifically grounded and individualized.
