How to Pass CTRN on Your First Try

Treat Flight Physiology as Genuinely New Material

If your background is bedside critical care or emergency nursing, flight physiology concepts (Boyle's Law, Dalton's Law, the effects of altitude on trapped gas and oxygen availability) likely aren't material you've studied before. Learn these concepts specifically and understand their clinical implications — why a pneumothorax can worsen at altitude, why hypoxia risk increases during air transport — rather than assuming general physiology knowledge covers this ground.

Practice Applying Core Clinical Knowledge Under Transport Constraints

You likely already know how to manage conditions like STEMI, DKA, or major trauma from your critical care or emergency background. The exam's twist is testing that knowledge in the context of a resource-limited, independent transport environment — a two-person crew, no immediate backup, limited equipment. Practice thinking through how your existing clinical knowledge changes (or doesn't) when applied to that setting.

Build Real Fluency With Special Populations

Pediatric, neonatal, obstetric, geriatric, and bariatric patients each have distinct physiological presentations and management priorities that general adult critical care experience may not deeply cover. Don't treat this domain as a quick review — if your clinical experience is adult-focused, budget real study time for these populations specifically.

Learn Crew Resource Management and Safety Concepts Concretely

Concepts like the sterile cockpit principle, crew resource management, and the authority to decline an unsafe mission are specific, testable content — not just general safety awareness. Study these as defined concepts with concrete definitions, since the exam tests them directly.

Review Obstetric and Trauma-in-Pregnancy Content Carefully

Because pregnant trauma patients require considerations (like positioning to avoid aortocaval compression) that don't apply to general trauma patients, and because obstetric emergencies like eclampsia and postpartum hemorrhage are high-stakes and time-sensitive, this content is worth deliberate, focused review even if obstetric transport isn't your most common case type.

One Last Practice Pass

Our CTRN exam page has free practice quizzes across all four domains, plus a full 100-question mock exam, to use as your final review before test day.
