CTRN and TCRN are different credentials from different certifying bodies: the CTRN (Certified Transport Registered Nurse) is administered by BCEN, while the TCRN (Trauma Certified Registered Nurse) is administered by BCEN. Which one fits depends on your role and career direction — the official eligibility rules and exam outlines (linked below) are the deciding documents. Here is a side-by-side view, plus free practice questions for both so you can feel the difference yourself.

The quickest way to judge which exam fits you is to answer real questions from each. These are genuine cards from both decks:
A transport nurse is picking up a patient from a scene involving a gunshot wound (GSW) that is now a crime scene. What is the priority for evidence preservation while maintaining the Chain of Custody during transport?
Show answer →Clinical care always takes priority, but evidence must be preserved. Key actions: Do not cut through bullet holes in clothing; bag each hand in paper bags (not plastic, which traps moisture and destroys DNA) if the patient is a suspect or victim of a struggle; and secure any physical evidence (bullets that fall out) in labeled containers. The Chain of Custody requires a continuous, documented record of everyone who had possession of the evidence. BCEN Exam Tip: If you must move evidence to provide care, document the original location and the reason for movement.
A patient sustained a 5% BSA burn from Hydrofluoric (HF) acid. They complain of pain out of proportion to exam and the EKG shows a prolonged QTc. What electrolyte abnormality is expected, and what is the specific treatment?
Show answer →Hypocalcemia (HF acid binds calcium and magnesium, forming insoluble salts). Treatment: Calcium Gluconate (topical gel, IV, or intra-arterial). Strategy: HF is unique because it causes deep tissue destruction and systemic toxicity even with small surface area burns. Watch for cardiac arrhythmias (Torsades de Pointes) due to profound hypocalcemia and hypomagnesemia.
When calculating CPP in a patient with both a TBI and a suspected spinal cord injury (SCI), how do the hemodynamic targets conflict, and which takes precedence?
Show answer →TBI targets focus on CPP (60-70 mmHg) and ICP (<22 mmHg). SCI targets focus on maintaining a high MAP (85-90 mmHg for 5-7 days) to ensure spinal cord perfusion. Conflict: Maintaining a MAP of 90 might result in a CPP > 80 in a patient with low ICP, which increases the risk for ARDS. Conversely, focusing only on a CPP of 60 might allow a MAP of 70, which is insufficient for the injured spinal cord. Precedence: In polytrauma, the highest MAP target usually takes precedence to ensure all injured neural tissues (brain and cord) are perfused. Exam Strategy: BCEN looks for the nurse's ability to balance multi-system goals. If both are present, the MAP target of 85-90 for SCI usually satisfies the CPP requirements for TBI.
A patient with a significant cerebellar mass undergoes placement of an EVD for obstructive hydrocephalus. Shortly after rapid CSF drainage, the patient becomes deeply comatose with fixed mid-position pupils. What rare herniation syndrome occurred?
Show answer →Upward (Cerebellar) Transtentorial Herniation. This occurs when a mass in the posterior fossa (or rapid decompression of the supratentorial space via EVD) pushes the cerebellum and brainstem upward through the tentorial notch. It results in compression of the midbrain. Clinical Pearl: This is a high-risk scenario when draining CSF too quickly from the ventricles in the presence of an infratentorial mass. Always drain CSF at the level/rate ordered.
They are independent credentials from BCEN and BCEN respectively; many professionals hold more than one certification. Check each body's eligibility requirements on the official sites linked above.
They test different bodies of knowledge, so difficulty depends on your background. Try free practice questions for both on this page — the one that feels further from your daily work will need more prep time.
Always use the certifying bodies directly: BCEN for the CTRN and BCEN for the TCRN. Links to both official sites are on this page.
Eligibility rules, fees, question counts and passing standards are set by the certifying body and change over time. Always confirm them at the source before you apply or schedule your exam — our flashcards are practice material, not the official handbook.
