Foundations of Trauma & Cardiac Support – Questions 1–12
Q1: During the primary survey of a trauma patient, which step comes immediately after
ensuring airway patency and cervical spine stabilization?
A. Inserting an oropharyngeal airway before assessing breathing
B. Assessing breathing, ventilation, and oxygenation
C. Applying a pelvic binder to control suspected hemorrhage
D. Performing a full neurologic examination to establish a Glasgow Coma Scale score
Correct Answer: B
Rationale: The best answer is B. This choice is correct because the ABCDE approach flows
in a strict sequence—once the airway is open and protected, you move directly to
breathing assessment. This aligns with the current BTCS guideline that emphasizes
addressing life-threatening issues in order before moving to the next step. In a real trauma
situation, skipping ahead to circulation or disability before confirming adequate ventilation
would miss tension pneumothorax or other immediately fatal problems.
Q2: A 34-year-old construction worker falls from a second-story scaffold. He is awake,
talking, and complaining of back pain. His vital signs are stable. According to standard
trauma triage principles, which factor most strongly supports transporting this patient to a
trauma center rather than a community emergency department?
A. The mechanism of injury involves a fall from a significant height
B. The patient is currently alert and oriented with stable vital signs
C. Back pain alone typically indicates minor musculoskeletal injury
D. Falls from less than three stories rarely warrant trauma center evaluation
Correct Answer: A
Rationale: The best answer is A. This choice is correct because falls from more than 20 feet
or significant height are a recognized mechanism of injury that meets trauma center
,criteria regardless of initial presentation. This matches the resuscitation principle that
serious injuries may not be immediately apparent, and mechanism matters as much as—or
more than—initial vital signs in triage decisions. In a real code situation, the priority would
be getting this patient to the right level of care before occult injuries declare themselves.
Q3: Which of the following best describes the purpose of the secondary survey in trauma
resuscitation?
A. It replaces the primary survey when the patient is hemodynamically stable
B. It is a rapid head-to-toe examination performed after life-threatening conditions are
addressed
C. It focuses exclusively on identifying fractures and dislocations
D. It should be completed within 60 seconds of patient arrival
Correct Answer: B
Rationale: The best answer is B. This choice is correct because the secondary survey is a
comprehensive head-to-toe evaluation that happens only after the primary survey is
complete and resuscitation efforts are underway. This aligns with the current BTCS
guideline that you do not move to secondary survey until airway, breathing, circulation,
disability, and exposure are managed. In a real trauma situation, the priority would be
stabilizing the patient first; the secondary survey helps catch injuries you might have
missed during the rapid primary assessment.
Q4: In the BTCS ABCDE approach, what is the recommended initial oxygen delivery for a
trauma patient with adequate spontaneous respirations but suspected hypoxemia?
A. 2 liters per minute via nasal cannula to avoid oxygen toxicity
B. 15 liters per minute via non-rebreather mask
C. High-flow oxygen at the maximum rate available via appropriate delivery device
D. Oxygen should be withheld until arterial blood gas results confirm hypoxemia
Correct Answer: C
Rationale: The best answer is C. This choice is correct because trauma patients in the
primary survey should receive high-flow oxygen immediately if there is any concern for
hypoxemia or inadequate tissue oxygenation. This aligns with the current BTCS guideline
that oxygen is a critical intervention during the breathing phase and should not be delayed
or titrated conservatively in the acute setting. In a real code situation, the priority would be
,preventing secondary brain injury and organ hypoperfusion by ensuring maximal oxygen
delivery early.
Q5: You are the first responder to a motor vehicle collision. The driver is trapped, slumped
over the steering wheel, and making gurgling sounds. There is moderate external bleeding
from a forearm laceration. What is your first priority?
A. Apply a tourniquet to the forearm to control the bleeding
B. Perform a jaw-thrust maneuver and suction the airway
C. Check for a carotid pulse to determine if CPR is needed
D. Stabilize the cervical spine with manual inline stabilization while assessing the airway
Correct Answer: D
Rationale: The best answer is D. This choice is correct because in any trauma patient with
a suspected mechanism for spinal injury, manual cervical spine stabilization must be
initiated simultaneously with airway assessment. This matches the resuscitation principle
that you protect the cervical spine from the moment you touch the patient. In a real code
situation, the priority would be establishing inline stabilization first; once that is
maintained, you can proceed to open the airway with a jaw-thrust and address the gurgling
sounds.
Q6: A trauma patient arrives in your bay with a heart rate of 128, blood pressure of 88/54,
respiratory rate of 24, and cool, clammy skin. These findings are most consistent with
which category of shock?
A. Distributive shock with systemic vasodilation
B. Hypovolemic shock from acute blood or fluid loss
C. Cardiogenic shock from primary pump failure
D. Neurogenic shock with loss of sympathetic tone
Correct Answer: B
Rationale: The best answer is B. This choice is correct because tachycardia, hypotension,
tachypnea, and cool clammy skin represent the classic presentation of hypovolemic shock.
This aligns with the current BTCS guideline that trauma patients lose volume through
hemorrhage, and the body compensates with vasoconstriction—hence the cold, clammy
extremities. In a real trauma situation, the priority would be identifying the source of
, bleeding and initiating volume resuscitation while preparing for definitive hemorrhage
control.
Q7: During the primary survey, you note that a patient's trachea is deviated to the left. The
right side of the chest is hyperresonant to percussion, and breath sounds are absent on the
right. The patient is becoming increasingly hypotensive and bradycardic. What is the most
appropriate immediate intervention?
A. Perform a needle decompression on the right side of the chest
B. Immediately intubate the patient using rapid sequence intubation
C. Begin bilateral chest compressions and activate the cardiac arrest team
D. Insert a large-bore IV and administer a 2-liter crystalloid bolus
Correct Answer: A
Rationale: The best answer is A. This choice is correct because tracheal deviation, absent
breath sounds, hyperresonance, and hemodynamic collapse are textbook signs of a tension
pneumothorax. This aligns with the current BTCS guideline that tension pneumothorax is a
clinical diagnosis requiring immediate needle decompression without waiting for imaging.
In a real trauma situation, the priority would be decompressing the affected side
immediately—delaying to obtain a chest X-ray would likely result in cardiac arrest.
Q8: Which vital sign change is typically the earliest indicator of significant blood loss in a
previously healthy adult trauma patient?
A. A drop in systolic blood pressure below 90 mmHg
B. Narrowing of the pulse pressure to less than 30 mmHg
C. An increase in heart rate above 100 beats per minute
D. A decrease in respiratory rate below 12 breaths per minute
Correct Answer: C
Rationale: The best answer is C. This choice is correct because tachycardia is the earliest
compensatory response to hypovolemia as the body attempts to maintain cardiac output.
This matches the resuscitation principle that young, healthy adults can lose up to 30% of
their blood volume before showing hypotension. In a real trauma situation, the priority
would be recognizing tachycardia as a warning sign and initiating hemorrhage control
before the patient decompensates into obvious hypotensive shock.
