AIR METHODS Flight Crew & Critical Care Pre-
Hire Exam | Complete Study Guide 2026/2027
Question 1
A flight crew is transporting an intubated patient. During ascent to
6,000 feet MSL, the paramedic notices that the endotracheal tube cuff
pressure increases significantly. Which gas law explains this
phenomenon?
• A. Dalton's Law
• B. Boyle's Law
• C. Charles' Law
• D. Henry's Law
Correct Answer: B
Detailed Rationale: Boyle's Law states that pressure and volume are
inversely proportional at a constant temperature (𝑃1 𝑉1 = 𝑃2 𝑉2 ). As
ambient barometric pressure decreases during ascent, the volume of air
trapped inside the sealed endotracheal tube cuff expands, increasing
internal cuff pressure against the tracheal wall.
Question 2
A severe traumatic brain injury (TBI) patient has a monitored
intracranial pressure (ICP) of 24 mmHg and a mean arterial pressure
(MAP) of 84 mmHg. What is the calculated cerebral perfusion pressure
(CPP)?
, • A. 60 mmHg
• B. 108 mmHg
• C. 50 mmHg
• D. 75 mmHg
Correct Answer: A
Detailed Rationale: Cerebral perfusion pressure is calculated using the
formula 𝐶𝑃𝑃 = 𝑀𝐴𝑃 − 𝐼𝐶𝑃. Subtracting the intracranial pressure (24
mmHg) from the mean arterial pressure (84 mmHg) yields a CPP of 60
mmHg, which represents the borderline minimum acceptable value for
adult TBI management guidelines.
Question 3
A patient rescued from a house fire has a pulse oximetry reading of
98%, cherry-red skin, and altered mental status. The flight paramedic
recognizes that pulse oximeter readings are unreliable here because
carbon monoxide causes which type of hypoxia?
• A. Hypoxic hypoxia
• B. Hypemic (anemic) hypoxia
• C. Stagnant hypoxia
• D. Histotoxic hypoxia
Correct Answer: B
Detailed Rationale: Hypemic hypoxia occurs when the oxygen-carrying
capacity of the blood is reduced. Carbon monoxide binds to hemoglobin
with an affinity 200 to 250 times greater than oxygen, forming
,carboxyhemoglobin, which standard pulse oximeters misread as
oxygenated hemoglobin.
Question 4
During an instrument flight rules (IFR) night transport, a pilot rapidly
moves their head to check a navigational chart and experiences an
overwhelming sensation of tumbling or pitching in a completely
different axis. This vestibular illusion is known as:
• A. The leans
• B. Coriolis illusion
• C. Autokinesis
• D. Somatogravic illusion
Correct Answer: B
Detailed Rationale: The Coriolis illusion occurs during prolonged
constant-rate turns when the pilot makes a head movement out of the
plane of rotation. This stimulates semicircular canals in multiple planes
simultaneously, creating a powerful, disorienting sensation that the
aircraft is tumbling.
Question 5
A patient presents with refractory cardiogenic shock and bradycardia
following an intentional metoprolol overdose. Which specific first-line
antidote bypasses beta-receptors to increase intracellular cyclic AMP?
• A. Atropine sulfate
• B. Glucagon
• C. Calcium chloride
, • D. Naloxone hydrochloride
Correct Answer: B
Detailed Rationale: Glucagon activates adenylate cyclase directly via a
receptor-independent mechanism, increasing intracellular cyclic AMP
levels to enhance myocardial contractility and heart rate independently
of beta-adrenergic receptors blocked by beta-blockers.
Question 6
What is the recommended balanced ratio of blood products in a
Massive Transfusion Protocol (MTP) for a patient experiencing severe
hemorrhagic shock from trauma?
• A. 1 unit of pRBCs to 5 units of normal saline
• B. 1 unit of pRBCs to 1 unit of fresh frozen plasma to 1 unit of
platelets (1:1:1)
• C. 4 units of platelets to 1 unit of pRBCs only
• D. 10 units of crystalloid to 1 unit of plasma
Correct Answer: B
Detailed Rationale: A balanced 1:1:1 ratio of packed red blood cells
(pRBCs), fresh frozen plasma (FFP), and platelets closely mimics whole
blood, preventing the lethal triad of trauma (coagulopathy, acidosis, and
hypothermia) associated with crystalloid overload.
Question 7
A mechanically ventilated patient with severe status asthmaticus
develops progressive hypotension and high peak airway pressures.
Which phenomenon is most likely causing this decompensation?
