Section 1: Trauma Care Fundamentals and Critical Thinking
1. According to the PHTLS 10th Edition philosophy, what is the foundational belief that underpins all
prehospital trauma care?
A. All trauma patients should be treated at the scene until they are hemodynamically stable
B. All trauma patients deserve the best possible care, and every practitioner has a duty to apply critical
thinking to optimize outcomes [CORRECT]
C. The primary goal of prehospital care is to provide definitive surgical intervention in the field
D. Prehospital care should prioritize airway management above all other interventions regardless of the
clinical situation
Correct Answer: B
Rationale: The PHTLS 10th Edition establishes as its philosophical foundation the belief that all trauma patients deserve the best
possible care and that every practitioner has a duty to apply critical thinking. Option A is incorrect because prolonged scene times are
discouraged. Option C is wrong because definitive surgical care occurs at the hospital, not in the field. Option D is incorrect because
the XABCDE approach prioritizes exsanguinating hemorrhage before airway in life-threatening scenarios.
2. Which of the following best describes the critical thinking process as defined in the PHTLS 10th
Edition?
A. A static decision-making framework applied once during initial patient assessment
B. A dynamic process requiring you to develop a plan, initiate it, reassess as care moves forward, and adjust
the plan as the patient condition or circumstances change [CORRECT]
C. A protocol-driven checklist that must be completed in order before transport
D. A process that relies solely on the clinical experience of the most senior provider on scene
Correct Answer: B
Rationale: The PHTLS critical thinking process is explicitly defined as dynamic, requiring continuous reassessment and adjustment.
Option A is incorrect because it describes a static approach, which contradicts the PHTLS model. Option C is wrong because PHTLS
emphasizes clinical judgment over rigid protocol adherence. Option D is incorrect because critical thinking is required of all
practitioners, not just the most senior.
3. What is the relationship between principles and preferences in PHTLS-guided prehospital care?
A. Preferences take priority over principles when the provider has extensive field experience
B. Principles define the required duties for optimizing patient survival; preferences are individual choices that
must not override evidence-based principles [CORRECT]
C. Principles and preferences carry equal weight in clinical decision-making
D. Preferences are established by medical directors and principles are established by field providers
Correct Answer: B
Rationale: PHTLS clearly distinguishes principles (evidence-based duties for optimizing survival) from preferences (individual
choices). Principles always take precedence. Option A is dangerous because experience never overrides evidence-based principles.
Option C is incorrect because they do not carry equal weight. Option D reverses the actual hierarchy, as principles come from
evidence-based science, not individual directors.
, 4. The Golden Period in trauma care refers to which of the following?
A. The first 60 minutes of life after a newborn experiences birth trauma
B. The time from injury to arrival at the appropriate site for definitive care, during which rapid transport is
critical to survival [CORRECT]
C. The period during which a tourniquet can remain safely applied before irreversible tissue damage occurs
D. The time window during which IV fluid resuscitation must be initiated to prevent irreversible shock
Correct Answer: B
Rationale: The Golden Period is defined in PHTLS as the time from injury to arrival at the appropriate site for definitive care. The
most important prehospital responsibility is to minimize scene time and expedite transport. Option A describes something unrelated to
trauma care. Option C describes a tourniquet safety concept, not the Golden Period. Option D describes shock resuscitation timing,
which is a different concept.
5. What is the Platinum Ten Minutes in the context of PHTLS prehospital trauma care?
A. The maximum amount of time a tourniquet should remain applied in the prehospital setting
B. The first 10 minutes after injury, during which prehospital providers should aim to minimize on-scene time
[CORRECT]
C. The recommended time limit for completing the primary survey on any trauma patient
D. The time frame within which hemorrhage control must be achieved to prevent coagulopathy
Correct Answer: B
Rationale: The Platinum Ten Minutes refers to the first 10 minutes after injury, emphasizing the need to minimize on-scene time.
Option A incorrectly references tourniquet safety. Option C confuses it with the primary survey, which does not have a universal
10-minute limit. Option D describes a different clinical concept related to damage control resuscitation.
6. Evidence-based practice in PHTLS is best described as the integration of which three components?
A. Protocols, physician orders, and patient transport decisions
B. Best available evidence, clinical expertise, and patient values [CORRECT]
C. Field experience, equipment availability, and scene conditions
D. Research studies, hospital policies, and insurance requirements
Correct Answer: B
Rationale: The PHTLS 10th Edition defines evidence-based practice as the integration of best available evidence, clinical expertise,
and patient values. This triad is the standard definition used throughout healthcare. Options A, C, and D describe operational
considerations but do not match the formal definition of evidence-based practice.
7. A PHTLS provider arrives at the scene of a motor vehicle collision. The patient has an isolated
femur fracture with no life-threatening hemorrhage. Which action best demonstrates the PHTLS
philosophy of the Golden Period?
A. Performing a comprehensive secondary survey on scene before initiating transport
B. Splinting the fracture on scene, reassessing, and initiating transport with minimal delay [CORRECT]
C. Waiting for additional EMS units to arrive before providing any care
D. Starting two large-bore IVs and administering a 1-liter fluid bolus before splinting
Correct Answer: B
Rationale: The Golden Period philosophy emphasizes minimizing on-scene time and expediting transport to definitive care. Splinting
the fracture and then initiating transport demonstrates this principle. Option A violates the Golden Period by delaying transport for a
non-life-threatening assessment. Option C unnecessarily delays care. Option D prioritizes interventions that are not indicated for this
stable patient over timely transport.
8. During a trauma call, a provider has a personal preference to apply a pelvic binder before assessing
for external hemorrhage. According to PHTLS principles, what should the provider do?
