CFRN · CTRN · general principles · safety and operations
Most of the general-principles domain is not clinical. Both outlines ask how a crew works a scene, talks on the radio, decides whether to go, handles a vehicle emergency and stays within the law with a patient on board.
CFRN, scene operations: scene safety, landing zone operations, disaster management, EMTALA.
CFRN, communications: radio operations, patient handoff, Air Medical Resource Management, Just Culture.
CFRN, safety and survival: navigation by map, GPS and night-vision goggles, survival principles, vehicle emergencies, pre-mission preparation.
CTRN, scene and vehicle: scene safety, emergency vehicle operations, vehicle emergencies and post-incident procedures, pre-mission preparation.
CTRN, communications and law: dispatch, handoff and crew resource management; EMTALA, legal concepts in patient care and consent.
Crew resource management, air and ground
Air Medical Resource Management is the air-medical form of crew resource management. The FAA's advisory circular on it (AC 00-64) frames it as training in communication, shared situational awareness and decision-making for everyone involved in a flight: pilots, medical crew, communications specialists and mechanics. The CTRN outline asks for the same skills under the plain name crew resource management.
Just Culture, also named in the CFRN outline, sorts events into human error, at-risk behavior and reckless behavior, and responds differently to each: support for the first, coaching for the second, sanctions only for the third.
Landing zones and the vehicle
Landing-zone questions test the ground side of the operation as much as the clinical one: the size and surface of the site, wires and obstacles, lighting at night, and how people move around a running aircraft. Programs publish their own minimums, and the exam asks for the principles rather than any one program's numbers. The CTRN version swaps the landing zone for emergency vehicle operations and the steps after a vehicle incident.
EMTALA and consent with a patient aboard
EMTALA's transfer rules bind the sending hospital; the hospital side is summarized in the TCRN study guide. The transport crew's part is narrower: it checks that what the rule (42 CFR 489.24) requires of the transfer is in place: an accepting hospital, the records, and qualified personnel and equipment for the trip.
Consent questions turn on capacity: who may consent for a patient who lacks it, and what changes when capacity returns during the trip.

Scene operations, communications, safety and preparation
A helicopter program plans outreach education for local volunteer fire departments that request its aircraft for scene flights. Which topic would MOST directly improve crew safety?
Answer and why, all 4 options
Teaching ground crews to set up a landing zone and approach a running aircraft prevents rotor strikes and obstacle accidents at scenes.
Triage tag rules matter in mass casualty incidents but do not address the hazards of the aircraft at the scene.
Billing documentation has nothing to do with crew safety.
Advanced airway skills are a clinical topic for the fire crew, not what keeps the flight crew safe at the scene.
Item 564172
Scene operations, communications, safety and preparation
The transport nurse arrives first at a bus crash and begins SALT triage with global sorting. Which group of patients is assessed individually FIRST?
Answer and why, all 4 options
Patients crying out loudly have a patent airway and enough perfusion to shout; they are not the first priority.
Patients who can walk to the collection area are assessed last.
In SALT global sorting, those who remain still or have an obvious threat to life are assessed first, then those who wave, then those who walk.
Patients who wave or move on command are assessed second, after those who are still or have obvious threats.
Item 564216
Scene operations, communications, safety and preparation
Firefighters are preparing a night landing zone for the incoming helicopter. Which action by the ground crew requires correction by the flight nurse?
Answer and why, all 4 options
Wetting a dusty surface reduces brownout and debris in the rotor wash.
Reporting wires to the pilot is correct practice; wires are a leading cause of crashes at scene landing zones.
A spotlight aimed at the aircraft blinds the pilot on approach; lights should point at the ground or at hazards.
Weighted lights at the corners mark the landing zone without blowing away in the rotor wash.
Item 564223
Scene operations, communications, safety and preparation
At a scene 7,500 ft above sea level on an 88 °F (31 °C) afternoon, the flight nurse learns the patient weighs 40 kg more than dispatch reported. Which action should the nurse take?
Answer and why, all 4 options
Removing gear is a decision for the pilot after recalculating performance; the nurse cannot guess the margin.
Calling a second aircraft is premature; the pilot first recalculates whether this aircraft can still do the flight.
Departing without telling the pilot ignores a weight change that can exceed what the aircraft can lift in hot, high conditions.
High altitude, heat and extra weight all reduce aircraft performance; only the pilot can recalculate whether the helicopter can safely lift off.
Item 565545
Scene operations, communications, safety and preparation
At a disaster scene, one helicopter is available for three critical patients. The nearest Level I trauma center (15 minutes away) reports that it is overwhelmed. A capable Level II trauma center (25 minutes away) has ample capacity. The BEST transport strategy is to
Answer and why, all 4 options
Delivering the sickest patient to an overwhelmed center delays that patient's care and adds to the overload.
When the nearest center is overwhelmed, taking a salvageable patient to a capable center with capacity gets the most patients to definitive care.
Waiting at the scene holds critical patients while the aircraft could already be moving one.
Overloading one aircraft exceeds its weight and space limits and makes care impossible.
Item 1882611
Scene operations, communications, safety and preparation
During a scene response for a 2-year-old child with a skull fracture, the caregiver's account of a fall from a couch does not match the injuries. The MOST appropriate action by the transport nurse is to
Answer and why, all 4 options
Confronting the caregiver can escalate the scene and endanger the child and crew.
Collecting evidence at the home is law enforcement's role; the crew's job is care and objective documentation.
Delaying transport of a child with a skull fracture to wait for police puts the child at risk.
Objective documentation of findings and exact statements in quotes supports the mandatory report and any later investigation.
Item 1882616
Scene operations, communications, safety and preparation
An unconscious trauma patient is being transported under implied consent. En route, the patient becomes alert, shows decision-making capacity, and asks the crew to stop giving IV fluids. The transport nurse should
Answer and why, all 4 options
A patient who regains capacity can refuse treatment; the nurse explains the risks, respects the choice and documents it.
Sedating a patient to continue treatment the patient has refused is battery.
Implied consent ends once the patient regains capacity and can speak for themself.
Medical control cannot override the informed refusal of a patient who has capacity.
Item 1882627
Scene operations, communications, safety and preparation
During a hurricane evacuation, a representative of a recognized disaster relief organization asks the transport team for the names and destinations of transported patients to help reunite families. The MOST appropriate response is to
Answer and why, all 4 options
HIPAA permits sharing the minimum location and status information with a disaster relief organization so families can be reunited.
The media have no right to patient information, and sharing with them first breaks privacy.
HIPAA allows disclosure to disaster relief organizations to locate and notify family; it is not an absolute bar.
The disaster relief provision is already part of HIPAA; no suspension is needed to share minimal information.
Item 1882628
Scene operations, communications, safety and preparation
During approach, the flight nurse notices that the weather is rapidly worsening while the pilot seems fixated on the landing zone. Using graded assertiveness in crew resource management, the nurse should FIRST
Answer and why, all 4 options
Declaring an emergency skips the steps that bring the pilot back into the loop and is not the nurse's role.
Graded assertiveness starts with an inquiry that invites the pilot to recheck, then escalates to a clear, direct statement of the concern.
Silence because of rank is exactly what crew resource management is designed to prevent.
Taking the controls is unsafe and outside the nurse's role; assertive communication is the tool.
Item 1882632
Scene operations, communications, safety and preparation
The same medication dosing error has occurred at several of a program's flight bases. Which approach BEST combines Just Culture and quality improvement principles?
Answer and why, all 4 options
Nonpunitive reporting brings errors to light, root cause analysis finds system factors, and small PDSA cycles test fixes before they spread.
A program-wide protocol before root cause analysis guesses at the cause and may not fix it.
Discipline for a system-wide error punishes individuals for system failures and discourages reporting.
Retraining everyone without looking at system factors assumes a knowledge gap that may not exist.
Item 1882636
Scene operations, communications, safety and preparation
While approaching a scene, the flight crew hears incident command say: "Medevac 1, hold at waypoint Alpha at 2,000 feet, drone activity in the sector." The MOST appropriate reply is
Answer and why, all 4 options
A correct read-back repeats the call sign and the key instruction, location and altitude, so the controller can catch a misunderstanding.
Holding at the present position is not what was assigned; the crew must hold at Alpha at 2,000 feet.
'Wilco' without the instruction leaves the controller unable to confirm what was understood.
'Roger' only confirms receipt and does not read back the hold point or altitude.
Item 1882670
Scene operations, communications, safety and preparation
After a helicopter crash in a freezing, remote area, the 406 MHz ELT is transmitting from the wreckage. A blizzard is approaching, and there is a sheltered rock overhang 100 yards away. The MOST appropriate plan is to
Answer and why, all 4 options
Staying in the open next to the wreck exposes the crew to the blizzard when shelter is only 100 yards away.
Turning off the ELT stops the signal that guides rescuers to the site.
Shelter nearby protects against the storm, and the running ELT keeps sending the crash location to rescuers.
Leaving the crash site makes the crew harder to find and exposes them to the blizzard.
Item 1882792
Scene operations, communications, safety and preparation
The communication center has not received the helicopter's scheduled 15-minute position report and cannot reach the crew by radio or satellite phone. What should the communication specialist do NEXT?
Answer and why, all 4 options
Waiting another 15 minutes loses time in the period when survivors most need rescue.
Calling the receiving hospital delays activation; it cannot locate the aircraft.
Launching another aircraft without coordination can put a second crew at risk; the incident plan directs a coordinated search.
A missed position report with no radio or satellite contact is treated as a possible accident, so the post-accident incident plan is activated at once.
Item 1882704
Scene operations, communications, safety and preparation
A scene request comes in with marginal weather en route and a reported tight, obstructed landing zone near the patient. Which risk-mitigation strategy is MOST appropriate?
Answer and why, all 4 options
Weather decisions belong to the pilot, and the medical crew should not be the one to accept or decline them.
Flying below minimum altitudes for visual reference is a classic path to controlled flight into terrain.
Accepting because the patient is critical is mission pressure; the patient's condition does not change weather or landing zone risk.
A larger alternate site with a ground EMS rendezvous avoids the obstructed zone while still getting the patient to air transport.
Item 1883035
Scene operations, communications, safety and preparation
The flight crew is dispatched to a shooting with several victims. Dispatch reports that law enforcement has not yet secured the scene. The crew's MOST appropriate action is to
Answer and why, all 4 options
The edge of an unsecured shooting scene is still within range of an active threat.
Scene safety comes first: the crew stages at a safe site and lands once law enforcement declares the scene secure.
Landing at an unsecured scene exposes the crew and aircraft to an active threat; injured rescuers become more patients.
Canceling abandons the victims; the crew can stage nearby and respond as soon as the scene is secured.
Item 565909
Scene operations, communications, safety and preparation
A transport program's quality review shows that rural referring hospitals often call for transport of trauma patients only after CT imaging is complete. Which outreach topic would MOST reduce time to definitive care?
Answer and why, all 4 options
Teaching crew procedures to referring staff does not change when they call for transport.
Activating transport on arrival by injury criteria, rather than after CT, starts the team moving while the patient is assessed and shortens time to definitive care.
Imaging protocols at the sending hospital lengthen the stay before transfer; the goal is to call before imaging.
Paperwork can be finished while the team is en route; it is not what delays the call.
Item 564175
Scene operations, communications, safety and preparation
In flight, smoke and a small flame appear at an electrical outlet beside the patient's oxygen tubing. The pilot has been alerted. Which action should the flight nurse take NEXT?
Answer and why, all 4 options
Liquid on an electrical fire risks shock and spreads the fault.
Fighting the flame while oxygen keeps feeding it lets it flare again.
Oxygen makes a small electrical fire burn hotter and faster, so the source is closed first, then the fire is put out.
More oxygen near the flame feeds the fire.
Item 9730039
Scene operations, communications, safety and preparation
After a forced landing in a remote clearing, the crew prepares fires to signal search aircraft. Which arrangement is the recognized distress signal?
Answer and why, all 4 options
Two fires do not form a recognized distress pattern.
Three of anything, such as three fires in a triangle, is the internationally recognized ground signal for distress.
A single fire can be a campfire and is not read as a distress call.
A square of fires is not a standard distress signal.

Well-meant errors in this domain
Loading a contaminated patient. Decontamination comes before the patient enters the aircraft or ambulance; a contaminated cabin takes the vehicle, and possibly the crew, out of service.
Talking to the pilot at the wrong moment. Commercial operators follow a sterile cockpit rule (14 CFR 135.100): no nonessential communication during critical phases of flight such as taxi, takeoff and landing. Clinical updates wait unless they affect safety.
Treating another program's turn-down as a detail. When a request arrives after another service declined for weather, the pilot needs to know before deciding.
