How many CFRN questions does SynkMind have?

1,128 original questions, counted once after overlap is removed, across 6 full-length forms, a practice bank, and end-of-lecture checks.

CFRN · the flight nursing certification

Everything the ICU does. At altitude.

Gas laws and the ventilated patient, resuscitation in a confined cabin, trauma and medical emergencies far from help — the CFRN tests critical care in transport. Every practice form is weighted to BCEN’s five-area content outline, and the lectures are the shared Emergency Core while CFRN’s own are written.

Your call · a real item from the Gauntlet 1 form

A patient rescued from a house fire has a carboxyhemoglobin level of 28% and a normal SpO2 on the pulse oximeter. Which type of hypoxia is present, and what does it imply for transport oxygen therapy?

Six full-length forms of 150

The real paper is 175 questions, 150 of them scored. Every full-length form here is the 150 that count. Weighted across BCEN content-outline areas the way the exam is. Three shorter forms of 100 sit beside them. 1,128 original questions in all, counted once.

Every wrong answer gets its own reason

Each explanation says why the right answer is right and why each distractor fails — the exact line you would want if you had picked it. Every item is checked blind by a second AI model that never sees the key. This one is a real item from the Diagnostic 1 form.

DIAGNOSTIC 1GENERAL PRINCIPLES OF FLIGHT TRANSPORT NURSINGEASY FORM

A ground crew is preparing a night landing zone and lights it with vehicle headlights.

How should the lighting be directed?

Point headlights upward toward the approaching aircraft for visibilityShining lights up blinds the pilot and degrades night vision, which is dangerous.

Use rotating strobes aimed at the cockpit to mark the landing zoneAiming strobes at the cockpit impairs the pilot's vision rather than helping.

Leave the zone dark so night-vision goggles work better for the crewA completely unmarked dark zone deprives the pilot of ground reference cues.

Aim lights at the ground to outline the zone, never up at the aircraftLanding-zone lights (headlights, spotlights) should illuminate the ground to define the zone and must never be pointed up at the aircraft, which blinds the pilot.

A tutor who asks what you do first — and why

Say what you are stuck on, out loud. Axon teaches the section in the voice of the flight nursing certification (BCEN CFRN), draws the reasoning on a board as it speaks, and quizzes you on it before it moves on. It knows your syllabus, your weak spots and where you left off.

Ten shared Emergency Core lectures. A check after every section.

The lectures are the Emergency Core written for CEN, shared while CFRN’s own are written; the practice forms and the question bank are CFRN’s own. 61 sections, each closed by its own knowledge check. Select any word on any page and Define opens a one-line meaning, why it matters and what it connects to — written for this exam.

Cardiovascular Emergencies7 sections · e.g. ED Chest Pain: Triage & the 10-Minute 12-Lead

Questions

Before you start

Is the full-length form the real length?

The real CFRN is 175 questions, 150 of them scored. Our full-length forms are the 150 that count, weighted across the five areas of BCEN’s content outline.

Are the lectures CFRN-specific?

Not yet. The ten lectures are the Emergency Core written for CEN, shared while CFRN’s own are written. The practice forms and the question bank are CFRN’s own.

Are these real exam questions?

No. Every item is original, written to the public content outline and checked blind by a second AI model that never sees the key. Nothing is copied from a published form, and we are not affiliated with any examining board.
