FP-C - Flight Paramedic-Certification Flight and Transport Physiology Questions and Answers

Question 1

A patient with a pneumothorax is being transported by helicopter.
As the aircraft ascends, the flight paramedic should be most concerned about which of the following gas laws causing a potential life-threatening emergency?

Accepted Answer

Boyle's Law

Answer

Dalton's Law

Answer

Henry's Law

Answer

Charles's Law

Question 2

You are transporting a patient with COPD from a rural facility at sea level to a tertiary care center located at a higher elevation. According to Dalton's Law, what physiological challenge should you anticipate?

Accepted Answer

Increased FiO2 requirement due to lower partial pressure of oxygen.

Answer

Expansion of gases in the bullae, causing a pneumothorax.

Answer

Decreased oxygen cylinder duration due to temperature changes.

Answer

Increased risk of decompression sickness.

Question 3

A flight paramedic is preparing to transport a patient with an endotracheal tube in a fixed-wing aircraft for a long-distance flight. To mitigate the effects of Boyle's Law on the ET tube cuff, the most appropriate action is to:

Accepted Answer

Continuously monitor the cuff pressure with a manometer and adjust as needed.

Answer

Inflate the cuff with the maximum recommended volume of air before takeoff.

Answer

Deflate the cuff completely during ascent and reinflate it at cruising altitude.

Answer

Inflate the cuff with sterile saline instead of air.

Question 4

Which of the following physiological stressors of flight is responsible for causing dehydration, drying of mucous membranes, and potentially thickening respiratory secretions?

Accepted Answer

Decreased Humidity

Answer

Vibration

Answer

Noise

Answer

Gravitational Forces

Question 5

A diver who ascended too rapidly is being transported for suspected decompression sickness. The formation of nitrogen bubbles in the blood and tissues is primarily explained by which gas law?

Accepted Answer

Henry's Law

Answer

Gay-Lussac's Law

Answer

Boyle's Law

Answer

Dalton's Law

Question 6

During a winter flight in a rotor-wing aircraft, the flight crew notes that the pressure gauge on their main oxygen cylinder reads lower than it did during their pre-flight check in the heated hangar. This phenomenon is best explained by:

Accepted Answer

Gay-Lussac's Law

Answer

Charles's Law

Answer

Dalton's Law

Answer

Boyle's Law
