AIR METHODS CRITICAL CARE EXAM: COMPLETE PRACTICE QUESTIONS
QUESTIONS 1-50: FLIGHT PHYSIOLOGY AND AVIATION SAFETY
1. According to Boyle's law, as altitude increases and barometric pressure
decreases, what happens to a closed air-filled space in the body?
A) It remains unchanged in volume
B) It decreases in volume
C) It increases in volume
D) It collapses completely
Correct Answer: C
Rationale: Boyle's law states that at constant temperature, gas volume is inversely
proportional to pressure. As altitude increases, ambient pressure decreases, causing
trapped gas in body cavities (pneumothorax, sinuses, middle ear, gastrointestinal tract)
to expand. This is a critical concept in flight physiology and explains why patients with
untreated pneumothorax should not be transported by air .
2. A patient with a pneumothorax being transported by helicopter begins to exhibit
worsening respiratory distress at altitude. Which gas law best explains this
deterioration?
A) Charles's law
B) Dalton's law
C) Henry's law
D) Boyle's law
Correct Answer: D
, Page 2 of 50
Rationale: Boyle's law explains that the reduction in barometric pressure at altitude
causes the trapped air in the pleural space to expand, worsening the pneumothorax.
This can lead to tension pneumothorax during ascent. For this reason, patients with
untreated pneumothorax should not be transported by air without a chest tube in
place .
3. Henry's law has the greatest clinical significance in air medical transport for
which patient condition?
A) Decompression sickness
B) Closed pneumothorax
C) Sinus barotrauma
D) Middle ear discomfort
Correct Answer: A
Rationale: Henry's law states that the amount of gas dissolved in a liquid is
proportional to the partial pressure of that gas. During ascent, decreased ambient
pressure causes dissolved nitrogen to come out of solution, forming bubbles in tissues.
This directly explains nitrogen bubble formation in decompression sickness .
4. Which type of hypoxia occurs when a patient with severe anemia has adequate
oxygen saturation but insufficient hemoglobin to carry oxygen to tissues?
A) Hypoxic hypoxia
B) Anemic hypoxia
C) Stagnant hypoxia
D) Histotoxic hypoxia
Correct Answer: B
Rationale: Anemic hypoxia results from reduced oxygen-carrying capacity of the blood
despite normal PaO₂ and SaO₂ values. Causes include anemia, carbon monoxide
poisoning, and methemoglobinemia. Hypoxic hypoxia (A) is due to low PaO₂; stagnant
hypoxia (C) is from inadequate circulation; histotoxic hypoxia (D) is from cellular
inability to use oxygen (cyanide poisoning) .
5. Dalton's law is most relevant to air medical transport in explaining the reduction
of which parameter at altitude?
A) Core body temperature
B) Partial pressure of inspired oxygen
, Page 3 of 50
C) Hemoglobin affinity for oxygen
D) Alveolar ventilation rate
Correct Answer: B
Rationale: Dalton's law explains that each gas's partial pressure is proportional to its
fraction of total pressure. As barometric pressure falls with altitude, the partial pressure
of inspired oxygen (PiO₂) decreases proportionally, even though the fraction of inspired
oxygen (21%) remains constant. This drives the reduction in alveolar PO₂ and leads to
hypoxia .
6. At a cabin altitude of 8,000 feet, the expected barometric pressure is
approximately what level?
A) 760 mmHg
B) 632 mmHg
C) 540 mmHg
D) 470 mmHg
Correct Answer: C
Rationale: At 8,000 feet, barometric pressure drops to approximately 540 mmHg. At
sea level (A), barometric pressure is 760 mmHg. This reduction in atmospheric pressure
has significant implications for oxygenation and gas expansion during flight .
7. According to Air Methods Clinical Practice Guidelines, what is the maximum
recommended scene time for a critical trauma patient requiring surgical
intervention?
A) 5 minutes
B) 10 minutes
C) 20 minutes
D) 30 minutes
Correct Answer: B
Rationale: Air Methods clinical guidelines emphasize the "Golden Hour" concept,
recommending that scene time for critical trauma patients be limited to 10 minutes or
less. This "scoop and run" approach prioritizes rapid transport to definitive surgical care
over on-scene interventions beyond lifesaving measures. Extended scene times are
associated with increased mortality in patients requiring surgical intervention .

8. How many feet shall an obstacle be cleared by on takeoff?
A) 15 feet
B) 30 feet
C) 50 feet
D) 100 feet
Correct Answer: B
Rationale: Standard obstacle clearance during takeoff requires maintaining at least 30
feet of clearance from any obstacles to ensure safe departure. This is a standard flight
safety requirement for helicopter operations .
9. What is the maximum descent rate below 300 feet AGL?
A) 100 feet per minute
B) 200 feet per minute
C) 500 feet per minute
D) 1000 feet per minute
Correct Answer: B
Rationale: To maintain safety during low-altitude approaches, the maximum descent
rate below 300 feet Above Ground Level (AGL) is 200 feet per minute. This controlled
descent rate ensures safety during low-altitude operations .
10. What is the "sterile cockpit" rule in air medical operations?
A) The cockpit must be cleaned between flights
B) Non-essential communication is prohibited during critical phases of flight
C) Only pilots are allowed in the cockpit
D) No food or drink in the cockpit
Correct Answer: B
Rationale: The "sterile cockpit" rule prohibits non-essential communication during
critical phases of flight (takeoff, approach, landing, and when operating below certain
altitudes). This allows pilots to focus on flight operations without distraction. Clinical
crew members are trained to observe sterile cockpit rules and limit communication to
essential operational information during these phases .
11. According to Air Methods' Safety Management System (SMS), which of the
following is TRUE regarding hazard reporting?
