Questions and Answers |Fall 2025/2026 Update | 100% Correct
1. Which gas law explains why an endotracheal tube cuff may increase pressure on the tracheal
wall during ascent in flight?
A. Boyle's Law
B. Charles's Law
C. Dalton's Law
D. Henry's Law
Correct Answer: A. Boyle's Law
Rationale: Boyle's Law states that at constant temperature, the volume of a gas is inversely
proportional to pressure. As altitude increases, atmospheric pressure decreases, causing
trapped gases (like in an ETT cuff filled at ground level) to expand, potentially leading to tracheal
ischemia if not adjusted.
2. In the primary assessment of a trauma patient during transport, the priority is to:
A. Obtain a detailed history
B. Identify and manage life-threatening conditions
C. Perform a full secondary survey
D. Secure intravenous access
Correct Answer: B. Identify and manage life-threatening conditions
Rationale: The primary survey in trauma care (ABCDE approach) focuses on immediate threats
to life, which is critical in the dynamic transport environment where delays or environmental
factors can worsen outcomes.
3. A characteristic associated with difficult bag-mask ventilation includes:
A. Short neck
, B. Facial hair
C. Dentures
D. Youthful age
Correct Answer: B. Facial hair
Rationale: Facial hair can prevent a proper seal with the mask, complicating ventilation. Other
predictors (e.g., from the MOANS mnemonic) include obesity, no teeth, age >55, and stiff lungs.
4. In a mass casualty incident during transport operations, treatment and transport priorities
should:
A. Follow first-come, first-served
B. Prioritize minor injuries for rapid discharge
C. Follow patient triage categories
D. Delay until full resources arrive
Correct Answer: C. Follow patient triage categories
Rationale: Triage systems (e.g., START or SALT) ensure resources are allocated to provide the
greatest good for the greatest number, with immediate (red) patients transported first when
feasible.
5. Acute fatigue in transport crew members is most commonly manifested by:
A. Increased alertness
B. Loss of accuracy and control
C. Improved decision-making
D. Enhanced physical strength
Correct Answer: B. Loss of accuracy and control
, Rationale: Fatigue impairs cognitive and psychomotor performance, increasing error risk in
high-stakes transport settings; crew resource management emphasizes monitoring for these
signs.
6. Which of the following is a common manifestation of acute fatigue in transport crew
members?
A. Increased alertness and improved reaction time
B. Observable decrease in cognitive performance and loss of accuracy
C. Enhanced physical strength and endurance
D. Better multi-tasking abilities under stress
Correct Answer: B. Observable decrease in cognitive performance and loss of accuracy
Rationale: Acute fatigue impairs cognitive functions, leading to reduced accuracy, slower
reaction times, and increased error risk in high-stakes transport environments. Crew resource
management training emphasizes recognizing these signs to maintain safety.
7. Knowing the mechanism of injury is important primarily because it:
A. Determines the exact diagnosis before arrival
B. Allows providers to anticipate certain types of injuries
C. Replaces the need for a physical assessment
D. Guides billing and documentation only
Correct Answer: B. Allows providers to anticipate certain types of injuries
Rationale: Understanding the mechanism (e.g., blunt vs. penetrating, high-speed deceleration)
helps predict patterns of injury (e.g., aortic disruption in rapid deceleration), enabling proactive
management during transport.
8. Henry's Law explains which phenomenon relevant to flight physiology?
A. Expansion of trapped gases in body cavities during ascent
B. The amount of gas dissolved in a liquid is proportional to the partial pressure of that gas
, C. Partial pressures of gases in a mixture
D. Volume changes due to temperature variations
Correct Answer: B. The amount of gas dissolved in a liquid is proportional to the partial
pressure of that gas
Rationale: Henry's Law is key in decompression sickness ("the bends"), where rapid ascent
reduces pressure, causing nitrogen bubbles to form in tissues and blood. This is a risk in
unpressurized flights after diving or certain exposures.
9. In disaster and mass-casualty incidents during transport, an important initial step is:
A. Transporting all patients immediately to the nearest hospital
B. Performing a risk assessment of both natural and manmade disasters
C. Focusing only on immediate (red tag) patients
D. Waiting for full incident command structure before acting
Correct Answer: B. Performing a risk assessment of both natural and manmade disasters
Rationale: Effective disaster response in transport requires assessing ongoing risks (e.g., scene
safety, secondary devices, environmental hazards) to protect crew and patients while
prioritizing resource allocation.
10. Which patient characteristic meets principles of field triage for direct transport to a trauma
center?
A. Isolated distal extremity fracture
B. Patients with two or more proximal long bone fractures
C. Minor soft tissue injuries
D. Age under 18 years alone
