Flight Nurse Practice Test: Free CFRN Exam Questions (Certified Flight Registered Nurse)

504 practice questions for the Certified Flight Registered Nurse (CFRN) exam, built on the content outline that took effect in August 2026. They follow its 5 domains, weighted the way the real exam is: Resuscitation Principles (40 of the 150 scored items), Medical Emergencies (35), General Principles of Flight Transport Nursing Practice and Trauma (30 each) and Special Populations (15), and they cover all 90 topics under them. Most are moments in the aircraft or at the sending bedside: what EMTALA requires before an unstable patient leaves, which RSI dose fits a patient in shock, why the plateau pressure matters, how to run norepinephrine by the numbers, what to do when an LVAD alarms, how to resuscitate a burn, and which drug is wrong for a laboring patient with asthma. Each is tagged to its outline topic, so your score report shows exactly where you miss, and every answer explains why the best choice is best and names its public source.

The real test: 175 questions (150 scored, 25 unscored pretest) in 3 hours at a PSI test center or by live remote proctoring, for registered nurses. It is not curved: on the content outline in effect since August 31, 2026 you need 102 of the 150 scored items right to pass, and you can retest after 90 days. It covers 5 domains: Resuscitation Principles (40 of the 150 scored items), Medical Emergencies (35), General Principles of Flight Transport Nursing Practice and Trauma (30 each) and Special Populations (15). Our practice test is full length, 150 scored questions plus 25 unscored in 180 minutes, split like the outline, passing at the same 102 of 150.

Here: 504 questions. Our own practice questions, built on BCEN's CFRN content outline (effective August 2026) and written from public sources (14 CFR Parts 91 and 135, 42 CFR 489.24, FAA handbooks and advisory circulars, AHA ACLS, PALS and neonatal guidelines, the Brain Trauma Foundation, AHA/ASA stroke guidelines, ARDSNet, Surviving Sepsis, KDIGO, ACOG, EAST, TCCC, CDC and NIH StatPearls), with every answer's source named. Topics are the 5 domains of the outline. Not BCEN's test questions. Free.
