INTRODUCTION
The Certified Flight Registered Nurse (CFRN) comprehensive assessment is
designed to evaluate the specialized knowledge and critical thinking skills required for
nursing practice in the transport environment. This exam encompasses a broad
spectrum of clinical scenarios, ranging from pre-hospital trauma stabilization to the
management of complex intensive care patients during interfacility transfer.
,Candidates are assessed on their ability to integrate flight physiology, advanced
pharmacology, and rapid decision-making under high-pressure conditions. The
structure utilizes multiple-choice questions and scenario-based inquiries to ensure a
rigorous validation of the nurse's competence in providing high-quality, autonomous
care while maintaining strict adherence to aviation safety and professional ethical
standards.
SECTION ONE: QUESTIONS 1–100
1. According to Boyle’s Law, as a flight nurse ascends with a patient who has an
untreated pneumothorax, what physiological change should be anticipated?
A. The volume of the pneumothorax will decrease.
B. The pressure within the pleural space will increase while volume remains constant.
🟢 C. The volume of the pneumothorax will increase.
D. The partial pressure of oxygen in the pleural space will rise.
🔴 RATIONALE: Boyle’s Law states that the volume of a gas is inversely proportional
to the pressure. As altitude increases and barometric pressure decreases, the volume
of trapped gas in a body cavity, such as a pneumothorax, will expand.
, 2. Which of the following is the most appropriate initial treatment for a patient
experiencing "the bends" (Type I Decompression Sickness) during a fixed-wing
transport?
A. Immediate descent to sea level and administration of 100% oxygen.
🟢 B. Administration of 100% oxygen and maintenance of the current cabin altitude.
C. Administration of IV fluids and Trendelenburg positioning.
D. Increasing the cabin altitude to decrease nitrogen solubility.
🔴 RATIONALE: Initial management focuses on 100% oxygen to facilitate the
washout of nitrogen. While descent is eventually necessary for hyperbaric treatment,
immediate oxygenation is the priority to prevent further bubble formation.
3. During a long-distance transport of a patient on a mechanical ventilator, the
"Stacking" of breaths is noted. This is most indicative of:
🟢 A. Auto-PEEP.
B. Ruptured ET tube cuff.
C. Oxygen toxicity.
D. Hypoventilation.
, 🔴 RATIONALE: Breath stacking, or Auto-PEEP, occurs when the expiratory phase is
too short to allow for full exhalation, leading to air trapping and increased intrathoracic
pressure.
4. A patient with a traumatic brain injury (TBI) has a Mean Arterial Pressure (MAP)
of 85 mmHg and an Intracranial Pressure (ICP) of 20 mmHg. What is the
calculated Cerebral Perfusion Pressure (CPP)?
A. 105 mmHg
B. 60 mmHg
🟢 C. 65 mmHg
D. 70 mmHg
🔴 RATIONALE: CPP is calculated by the formula MAP - ICP. In this case, 85 - 20 =
65 mmHg. A CPP of 60–70 mmHg is generally targeted in TBI patients.
5. In the context of flight safety, what is the "sterile cockpit" rule?
A. No talking is allowed during the entire flight duration.
B. The medical crew must remain in the back of the aircraft at all times.
🟢 C. Only communication essential to the safety of the flight is permitted during
