CFRN Flight and Transport 2

Question 1

During a rotor-wing transport at 8,000 feet MSL, an unventilated pneumothorax is most likely to worsen because of which gas law?

Accepted Answer

Boyle's Law

Answer

Boyle's Law states that as pressure decreases with altitude, gas volume expands, causing a pneumothorax to enlarge.

Question 2

A flight nurse is transporting a patient with an endotracheal tube inflated with air at sea level. At altitude, the cuff pressure will most likely:

Accepted Answer

Increase due to expansion of trapped air

Answer

Air in the ETT cuff expands at altitude per Boyle's Law, increasing cuff pressure and risking tracheal mucosal ischemia.

Question 3

When preparing a patient with a PASG (pneumatic anti-shock garment) for air transport, the flight nurse should:

Accepted Answer

Monitor and adjust pressure during altitude changes

Answer

PASG compartments expand at altitude so pressure must be monitored and released incrementally to prevent over-inflation.

Question 4

Which type of transport aircraft provides the most stable platform for performing advanced interventions such as defibrillation or surgical airways?

Accepted Answer

Fixed-wing pressurized aircraft

Answer

Pressurized fixed-wing aircraft offer greater cabin space, altitude control, and reduced vibration, making advanced interventions easier to perform.

Question 5

A flight nurse notices significant rotor wash during patient loading. The correct safety approach for ground personnel is to:

Accepted Answer

Wait for the pilot's hand signal and approach from the front in the pilot's line of sight

Answer

Personnel should always approach in view of the pilot from the front, never from the rear where the tail rotor poses a lethal hazard.
