CFRN Practice Test 2025/2026 – 100+ Verified Questions with Answers & Rationales | Airway, Altitude Physiology, Trauma, OB, Neonatal, Vent Settings, Burns & Critical Transport Protocols

This advanced-level practice test includes over 100+ accurate, exam-style questions with correct answers and clinical rationales specifically written for the Certified Flight Registered Nurse (CFRN) exam, aligned with the 2025/2026 certification cycle by the Board of Certification for Emergency Nursing (BCEN). This resource targets high-acuity scenarios encountered in air medical transport, offering expert-level reasoning grounded in critical care, trauma, and aviation physiology. Key content areas covered: Altitude & Flight Physiology: Dalton’s Law, Boyle’s Law, hypoxia types, atmospheric pressure shifts, gas expansion, hypoxic triggers at altitude Airway & Ventilation: Intubation meds, ventilator settings (I:E ratio, PEEP, rate), ETT confirmation, ETCO₂ targets, pressure support Trauma & Shock: Burns (Parkland formula), pelvic fracture stabilization, hemorrhagic shock signs, crush injuries, airway burns Obstetric & Neonatal Transport: Eclampsia, magnesium toxicity, fetal monitoring interpretation, Apgar scoring, neonatal resuscitation drug dosing Pediatrics & Critical Interventions: Broselow tape, fluid boluses, pediatric intubation parameters, trauma brain injury in children Flight & Transport Equipment: Portable vent troubleshooting, aircraft safety, weight distribution, altitude sickness management Pharmacology & Labs: Drug interactions during transport, blood product administration, electrolyte shifts, and ventilator drug compatibility This resource is ideal for CFRN candidates, transport nurses, and critical care professionals preparing for the unique demands of high-risk air and ground transfers. All questions reflect BCEN-level complexity, with focus on physiology, safety, and clinical intervention in austere environments. Recommended for: Courses: CFRN Review, Flight Nursing Essentials, Advanced Airway Management, Pediatric Critical Care Programs: BCEN CFRN Certification Prep, Flight Nurse Residency, Critical Care Transport Training Users: Flight nurses, transport RNs, trauma nurses, EMS-to-RN professionals, nurse educators, and CCRNs advancing into flight roles Keywords: CFRN 2025, flight nurse exam, airway management, ventilator settings, altitude physiology, Dalton’s Law, eclampsia, neonatal resuscitation, Apgar score, Parkland formula, hypoxia, ETCO2, pediatric trauma, pelvic fracture, magnesium toxicity, transport safety, hypovolemia, critical care transport, Broselow tape, BCEN certification
