Core Domains
Kinematics of Trauma: Analysis of energy transfer and prediction of injury patterns.
Airway and Ventilation Management: Advanced oxygenation strategies and difficult
airway algorithms.
Shock and Resuscitation: Pathophysiology of perfusion and balanced fluid resuscitation.
Abdominal and Thoracic Trauma: Identification and management of life-threatening
internal injuries.
Neurological Trauma: Management of Traumatic Brain Injury (TBI) and spinal cord
protection.
Special Populations: Tailoring trauma care for pediatric, geriatric, and obstetric patients.
Introduction
This comprehensive evaluation is designed to challenge the clinical reasoning and split-second
decision-making required of advanced trauma providers. Moving beyond rote memorization,
this assessment focuses on the synthesis of the PHTLS philosophy—specifically the
,identification of the "X-A-B-C-D-E" sequence in high-pressure environments. Candidates must
demonstrate the ability to evaluate complex kinematics, prioritize interventions in multi-system
trauma, and apply evidence-based protocols to mitigate secondary injury. Each scenario is
crafted to mirror the unpredictability of prehospital care, requiring a deep understanding of
pathophysiology to ensure optimal patient outcomes in the golden period of trauma.
1. A 24-year-old male is found unconscious after a high-speed motorcycle collision. He has
obvious bilateral femur fractures and a rigid, distended abdomen. His vitals are HR 135,
BP 78/42, RR 26. What is the most appropriate initial fluid management strategy?
A. Administer 2 liters of room temperature Normal Saline rapidly.
B. Initiate heated isotonic crystalloid boluses in 250mL increments to maintain a palpable
radial pulse.
C. Administer hydroxyethyl starch to provide rapid volume expansion.
D. Withhold all fluids until the patient reaches a Level 1 Trauma Center.
Correct Answer: Initiate heated isotonic crystalloid boluses in 250mL increments to
maintain a palpable radial pulse.
Rationale: PHTLS 10th edition emphasizes "balanced resuscitation" or permissive
hypotension for non-compressible hemorrhage. Titrating small boluses to a target systolic
BP of 80-90 mmHg (or a palpable radial pulse) limits the disruption of formed clots and
prevents the exacerbation of the "lethal triad" of trauma.
2. You are treating a patient who was caught in a structural collapse. He has a crushed lower
extremity that has been pinned for 4 hours. Before releasing the weight, which medication
should be prioritized to mitigate reperfusion injury?
, A. Intravenous Epinephrine 1:10,000.
B. Sodium Bicarbonate and IV fluids.
C. Sublingual Nitroglycerin.
D. Intramuscular Glucagon.
Correct Answer: Sodium Bicarbonate and IV fluids.
Rationale: Crushed tissue releases potassium, myoglobin, and lactic acid. Once the
pressure is released, these toxins enter the systemic circulation (crush syndrome). Pre-
treating with IV fluids and Sodium Bicarbonate helps alkalinize the urine and manage
hyperkalemia, protecting the kidneys and heart.
3. An adult female was involved in a lateral impact motor vehicle collision (T-bone). She
complains of severe "tearing" pain between her scapulae and exhibits a blood pressure
differential of 30 mmHg between her right and left arms. What injury should you suspect?
A. Tension pneumothorax.
B. Traumatic aortic disruption.
C. Cardiac tamponade.
D. Ruptured diaphragm.
Correct Answer: Traumatic aortic disruption.
Rationale: Lateral or frontal deceleration injuries often cause the heart to swing forward,
shearing the aorta at the ligamentum arteriosum. A BP differential between limbs and
interscapular pain are classic indicators of this high-mortality injury.
4. A patient presents with a gunshot wound to the right chest. You note decreased breath
sounds on the right side, jugular venous distention (JVD), and hyperresonance upon
, percussion. The patient is increasingly dyspneic. What is the immediate intervention?
A. Pericardiocentesis.
B. Needle decompression in the 5th intercostal space, anterior axillary line.
C. Application of a four-sided occlusive dressing.
D. Intubation with positive pressure ventilation.
Correct Answer: Needle decompression in the 5th intercostal space, anterior axillary line.
Rationale: The presence of JVD and hyperresonance (rather than dullness) points to a
tension pneumothorax rather than a hemothorax. PHTLS 10th edition recommends the
5th intercostal space, anterior axillary line as a preferred site for needle decompression in
adults.
5. While managing a 70-year-old male who fell down a flight of stairs, you note he is on
Warfarin (Coumadin) for atrial fibrillation. He is conscious but confused (GCS 13). Why is
this patient at significantly higher risk than a younger patient with the same injury?
A. Age-related brain atrophy increases the distance the bridging veins must span.
B. Geriatric patients have more flexible skulls which absorb less energy.
C. Warfarin causes immediate vasodilation of the cerebral arteries.
D. Older patients have a higher baseline intracranial pressure.
Correct Answer: Age-related brain atrophy increases the distance the bridging veins
must span.
Rationale: In elderly patients, brain atrophy creates more space within the cranium,
stretching the bridging veins. Even minor trauma can cause these veins to tear, leading to
a subdural hematoma, which is further complicated by the patient’s anticoagulation
therapy.
