Question 1
According to Dalton's Law of Partial Pressures, what happens to the
total pressure and the partial pressure of individual gases as altitude
increases?
• A. Both total pressure and partial pressure increase.
• B. Total pressure decreases, while the percentage of oxygen in the
air decreases.
• C. Total barometric pressure decreases, causing a proportional
decrease in the partial pressure of oxygen.
• D. Total pressure remains constant, but nitrogen partial pressure
increases.
Correct Answer: C
Detailed Rationale: Dalton's Law states that the total pressure of a gas
mixture is the sum of the partial pressures of its component gases. As
altitude increases, barometric pressure decreases, which directly
decreases the partial pressure of oxygen (hypoxia of ascent), even
though the fraction of inspired oxygen remains roughly 21% in the
atmosphere.
,Question 2
A patient with a tension pneumothorax is being transported by
helicopter. As the aircraft ascends to 5,000 feet, which gas law explains
the expansion of trapped air in the pleural space?
• A. Boyle's Law
• B. Charles' Law
• C. Henry's Law
• D. Graham's Law
Correct Answer: A
Detailed Rationale: Boyle's Law states that at a constant temperature,
the volume of a given mass of gas is inversely proportional to its
pressure. As altitude increases and barometric pressure decreases,
trapped gases inside body cavities expand in volume, potentially
worsening a pneumothorax into a tension pneumothorax.
Question 3
During rapid sequence induction (RSI) for a severe traumatic brain
injury patient prior to flight, which neuromuscular blocking agent is
generally preferred unless specific contraindications exist?
• A. Pancuronium
• B. Succinylcholine
• C. Vecuronium
• D. Cisatracurium
Correct Answer: B
,Detailed Rationale: Succinylcholine is a depolarizing neuromuscular
blocker with a rapid onset (45 to 60 seconds) and short duration (3 to 5
minutes), making it ideal for RSI when a quick return of spontaneous
breathing is desired if intubation fails. However, caution must be used in
patients with burns, crush injuries, or renal failure due to the risk of
hyperkalemia.
Question 4
A trauma patient intubated and ventilated during flight suddenly
develops severe hypotension, absent breath sounds on the right side,
tracheal deviation to the left, and jugular venous distention. What is the
immediate life-saving intervention?
• A. Immediate administration of IV fluids
• B. Needle decompression of the right 2nd intercostal space
• C. Emergency pericardiocentesis
• D. Increasing the ventilator tidal volume
Correct Answer: B
Detailed Rationale: The clinical presentation indicates a tension
pneumothorax, which compromises venous return and causes
obstructive shock. The immediate, definitive pre-hospital and flight
intervention is needle thoracostomy in the second intercostal space at
the mid-clavicular line, followed by chest tube insertion.
Question 5
When infusing norepinephrine via a peripheral IV line during critical
care transport, the flight crew must be highly vigilant for which local
complication?
, • A. Localized allergic dermatitis
• B. Tissue extravasation leading to severe ischemia and necrosis
• C. Immediate venous thrombosis of the entire limb
• D. Local muscle hyper-reflexia
Correct Answer: B
Detailed Rationale: Norepinephrine is a potent alpha-1 and beta-1
adrenergic agonist. Extravasation from a peripheral IV site causes
intense local vasoconstriction, which can lead to severe tissue ischemia,
sloughing, and necrosis. Central line access is preferred, and if
extravasation occurs, phentolamine is used as an antidote.
Question 6
A mechanically ventilated patient with acute respiratory distress
syndrome is being transported. To prevent ventilator-induced lung
injury, the flight paramedic should target which lung-protective
ventilation parameter for tidal volume?
• A. 10 to 12 mL/kg of ideal body weight
• B. 4 to 8 mL/kg of ideal body weight
• C. 12 to 15 mL/kg of actual body weight
• D. 2 mL/kg of actual body weight
Correct Answer: B
Detailed Rationale: Lung-protective ventilation strategies for acute
respiratory distress syndrome recommend low tidal volumes (typically 4
to 8 mL/kg of ideal body weight) to minimize alveolar overdistension
