TCRN Exam Flashcards

Q: What is the TCRN certification exam?

The Trauma Certified Registered Nurse examination is BCEN's specialty certification exam for registered nurses practicing across the trauma care continuum. Eligibility requires a current, unencumbered RN license or an accepted international equivalent. BCEN recommends at least two years of specialty experience, but does not require it.

Q: How many items are on the TCRN exam, and what score is required?

The exam contains 175 items: 150 scored items and 25 unscored pretest items. Candidates have 180 minutes and must answer 96 of the 150 scored items correctly. BCEN states that the passing standard is criterion-based rather than curved.

Q: How is the current TCRN content outline weighted?

The outline effective November 29, 2025 allocates 31 scored items to Head and Neck, 38 to Trunk and Pelvis, 13 to Musculoskeletal and Wound, 22 to Special Populations, 36 to Continuum of Care for Trauma, and 10 to Professional Practice.

Q: How is the TCRN exam delivered?

BCEN delivers the computer-based exam through PSI at testing centers or through PSI Live Remote Proctoring. After approval, candidates must schedule and sit within their 90-day eligibility window; both delivery modes use the same examination and security standards.

Q: What is the TCRN retake policy after a failed attempt?

BCEN allows unlimited attempts but requires a 90-day waiting period after every failed attempt. The candidate may submit a new retest application through the BCEN account only after that waiting period has ended. No separate longer wait is published after three failures.

Q: Does BCEN publish a TCRN pass rate?

BCEN publishes annual counts of examinations delivered, passed, and failed, but it does not publish an official TCRN pass-rate percentage or a first-attempt pass-rate breakdown. This set therefore does not infer a percentage from those counts.

Question 1

What prevents secondary brain injury after traumatic brain injury?

Accepted Answer

Prevent hypoxemia and hypotension, maintain ventilation near normocapnia unless treating imminent herniation, and trend GCS, pupils, motor findings, oxygenation, and perfusion. A normal initial scan or examination does not replace serial reassessment because deterioration may be delayed.

Question 2

How do epidural and acute subdural hematomas differ?

Accepted Answer

An epidural hematoma is typically lens-shaped on CT and often arterial; a lucid interval may occur. An acute subdural hematoma is crescent-shaped and usually reflects torn bridging veins with associated brain injury. Neurologic decline with either requires immediate neurosurgical escalation.

Question 3

What does a Cushing response indicate in a trauma patient?

Accepted Answer

Hypertension with widening pulse pressure, bradycardia, and irregular respirations is a late sign of critically increased intracranial pressure and possible herniation. It is not the expected pattern of uncomplicated hemorrhagic shock and demands immediate airway and neurosurgical action.

Question 4

When is hyperventilation appropriate in severe traumatic brain injury?

Accepted Answer

Brief controlled hyperventilation is a rescue bridge for signs of imminent herniation while definitive treatment is arranged. Routine or prolonged prophylactic hyperventilation can reduce cerebral blood flow; prioritize oxygenation, perfusion, head-neutral positioning, and prescribed hyperosmolar therapy.

Question 5

Which findings suggest a basilar skull fracture, and what route should be avoided?

Accepted Answer

Battle sign, periorbital ecchymosis, hemotympanum, or cerebrospinal fluid leakage from the nose or ear are warning findings. Avoid blind nasal tubes or nasotracheal instrumentation when skull-base or severe midface injury is suspected; use an oral route when indicated.

Question 6

What is the immediate nursing protection for a suspected open-globe injury?

Accepted Answer

Place a rigid eye shield without pressure, keep the patient NPO, control pain and vomiting, and obtain urgent ophthalmologic care. Do not patch tightly, palpate the eye, measure intraocular pressure, remove an embedded object, or perform ocular ultrasound over a suspected open globe.

Question 7

How do neurogenic shock and spinal shock differ?

Accepted Answer

Neurogenic shock is distributive circulatory failure after spinal cord injury, classically hypotension with relative bradycardia and warm skin after hemorrhage is excluded. Spinal shock is temporary loss of motor, sensory, reflex, and autonomic function below the lesion; it describes neurologic physiology, not blood pressure.

Question 8

Why can a high cervical spinal cord injury cause delayed respiratory failure?

Accepted Answer

The diaphragm depends on C3-C5 innervation, while intercostal and abdominal muscle weakness impairs ventilation and cough. Trend work of breathing, voice, secretion clearance, gas exchange, and respiratory strength; apparent early stability can precede fatigue and the need for a definitive airway.

Question 9

How do central cord and anterior cord syndromes differ?

Accepted Answer

Central cord syndrome typically causes greater motor weakness in the upper extremities than the lower extremities. Anterior cord syndrome causes motor loss plus loss of pain and temperature below the lesion while dorsal-column vibration and position sense are relatively preserved.

Question 10

When should blunt cerebrovascular injury be suspected?

Accepted Answer

Suspect carotid or vertebral injury with an unexplained focal neurologic deficit, arterial neck bleeding or bruit, expanding hematoma, high-risk cervical or skull-base fractures, or a concerning neck-seatbelt mechanism. Escalate for protocol-based CT angiography and antithrombotic planning when bleeding risk permits.

Question 11

What are hard signs of penetrating neck vascular or aerodigestive injury?

Accepted Answer

Active or pulsatile bleeding, expanding hematoma, shock, bruit or thrill, air bubbling from the wound, airway compromise, major hemoptysis or hematemesis, and focal neurologic deficit require immediate operative and airway escalation. Do not blindly probe or clamp the wound.

Question 12

Why is tension pneumothorax treated before imaging?

Accepted Answer

Tension pneumothorax is a clinical diagnosis when unilateral breath-sound loss and respiratory distress progress to obstructive shock. Immediate decompression is required; needle or finger decompression is a bridge and should be followed by definitive tube thoracostomy as soon as feasible.

Question 13

How is an open pneumothorax initially managed?

Accepted Answer

Cover the defect with a vented chest seal and give oxygen while arranging tube thoracostomy at a separate site. Continuously reassess for tension physiology; an occlusive seal that cannot vent may convert the injury to a tension pneumothorax.

Question 14

What makes a traumatic hemothorax immediately dangerous?

Accepted Answer

Blood in the pleural space can cause both hemorrhagic shock and ventilatory compromise. Support circulation, place a chest tube, quantify output, and escalate urgently for operative control when the initial return is massive, bleeding persists, or transfusion needs continue.

Question 15

What are the priorities for flail chest with pulmonary contusion?

Accepted Answer

Provide oxygenation, effective multimodal analgesia, pulmonary hygiene, and close monitoring for evolving respiratory failure. Do not bind the chest. Escalate to noninvasive or invasive ventilatory support when gas exchange or work of breathing fails rather than intubating solely because a flail segment exists.

Question 16

Why can cardiac tamponade be missed after trauma?

Accepted Answer

The full Beck triad is often absent, especially with hypovolemia or positive-pressure ventilation. Suspect obstructive shock with jugular venous distention, muffled heart sounds, narrow pulse pressure, or unexplained arrest; bedside ultrasound supports the diagnosis, but unstable patients need immediate decompression or operative control.

Question 17

What is the stable-patient pathway for suspected blunt thoracic aortic injury?

Accepted Answer

High-energy deceleration or suggestive chest imaging warrants CT angiography in a hemodynamically stable patient. Once diagnosed, reduce aortic shear with carefully titrated impulse control when not contraindicated and obtain urgent trauma and vascular input; injury grade and associated injuries determine surveillance versus endovascular repair.

Question 18

What determines operative versus nonoperative care for blunt solid-organ injury?

Accepted Answer

Hemodynamic response and peritoneal findings drive the decision more than injury grade alone. Stable patients without peritonitis may undergo monitored nonoperative management with serial examinations and possible angioembolization; persistent instability or peritonitis requires rapid hemorrhage control.

Question 19

Why do hollow-viscus injuries require serial reassessment?

Accepted Answer

Early CT and examination findings may be subtle. Increasing abdominal pain, guarding, fever, leukocytosis, rising lactate, free air, bowel-wall abnormality, or mesenteric injury should raise concern for leakage or ischemia and trigger urgent surgical reassessment.

Question 20

What findings suggest traumatic diaphragmatic rupture?

Accepted Answer

Consider it after major thoracoabdominal trauma when abdominal viscera appear in the chest, bowel sounds are heard above the diaphragm, or unexplained respiratory compromise persists. Gastric decompression may improve ventilation, but definitive management is surgical repair.

Question 21

Where should a pelvic binder be positioned?

Accepted Answer

Center the binder over the greater trochanters, not the iliac crests, to reduce pelvic volume and stabilize the ring. Document application time, reassess distal perfusion and skin, and avoid repeatedly releasing the binder before a definitive plan is established.

Question 22

What are the immediate priorities in unstable pelvic-fracture hemorrhage?

Accepted Answer

Apply a correctly positioned binder, activate balanced blood-product resuscitation, prevent hypothermia, and move rapidly to definitive hemorrhage control. Angioembolization targets arterial bleeding, while preperitoneal packing or operative strategies may be needed for venous, bony, or associated intra-abdominal bleeding.

Question 23

What should happen before urinary catheterization when urethral injury is suspected?

Accepted Answer

Blood at the meatus, inability to void, or perineal or scrotal hematoma after pelvic trauma warrants retrograde urethrography before blind urethral catheterization. A 'high-riding prostate' is neither sensitive nor required; use suprapubic drainage if directed when urethral disruption is confirmed.

Question 24

How do intraperitoneal and uncomplicated extraperitoneal bladder ruptures differ?

Accepted Answer

Gross hematuria with pelvic trauma should prompt retrograde cystography when bladder injury is suspected. Intraperitoneal rupture usually requires operative repair; uncomplicated extraperitoneal rupture is often managed with catheter drainage, while bladder-neck injury or bone fragments may require surgery.

Question 25

What is the earliest useful warning pattern for acute compartment syndrome?

Accepted Answer

Pain out of proportion and pain with passive stretch are early warnings, followed by tense swelling and sensory or motor change. Normal pulses do not exclude compartment syndrome because arterial flow may persist; remove constriction and obtain immediate surgical evaluation for fasciotomy.

Question 26

What are the first priorities for an open fracture?

Accepted Answer

Control hemorrhage, document distal neurovascular status, cover with a sterile dressing, align and splint as indicated, and give early protocol-directed antibiotics and tetanus prophylaxis. Do not repeatedly inspect, irrigate aggressively at bedside, or push exposed bone back through the wound.

Question 27

How should an amputated body part be preserved for transport?

Accepted Answer

Wrap it in sterile saline-moistened gauze, seal it in a clean watertight bag, and place that bag in a second container with ice and water. Do not place tissue directly on ice, immerse it in water, scrub it, or delay care of the patient to manage the part.

Question 28

What makes crush injury dangerous after pressure is released?

Accepted Answer

Reperfusion can release potassium, acids, and myoglobin, causing dysrhythmia, shock, and acute kidney injury. Start early isotonic fluid when appropriate, monitor ECG, potassium, urine output, creatine kinase, and renal function, and treat hyperkalemia immediately according to protocol.

Question 29

Why is hypotension a late warning in pediatric trauma?

Accepted Answer

Children can maintain blood pressure through vasoconstriction and tachycardia despite substantial blood loss, then deteriorate rapidly when compensation fails. Use age-adjusted vital signs, mental status, skin perfusion, pulses, and urine output, and use weight-based equipment, medications, and blood products.

Question 30

How can geriatric trauma hide shock and serious injury?

Accepted Answer

Beta-blockers, pacemakers, hypertension, frailty, and limited physiologic reserve can blunt tachycardia or make an apparently normal pressure misleading. Review anticoagulants, compare with baseline, trend perfusion and mentation, and maintain a low threshold for imaging and escalation after even low-energy mechanisms.

Question 31

What is the first resuscitation principle in pregnant trauma?

Accepted Answer

Maternal stabilization is the best initial fetal resuscitation: manage airway, oxygenation, ventilation, and hemorrhage first. After about 20 weeks, use manual left uterine displacement or left lateral tilt to reduce aortocaval compression while preserving spinal precautions and obtain obstetric and fetal assessment when feasible.

Question 32

Which burns count toward total body surface area for fluid calculations?

Accepted Answer

Count partial-thickness and full-thickness burns; do not count superficial erythema. Use a Lund-Browder chart for the most age-accurate estimate, especially in children; the patient's entire palmar hand is roughly 1% for scattered burns. Titrate resuscitation to response rather than a formula alone.

Question 33

Why can pulse oximetry look normal in carbon monoxide poisoning?

Accepted Answer

Standard pulse oximetry cannot distinguish oxyhemoglobin from carboxyhemoglobin and may be falsely reassuring. Give high-concentration oxygen, obtain co-oximetry, and consider early intubation when facial burns, soot, progressive hoarseness, stridor, or edema threaten the airway.

Question 34

What is the first decontamination sequence for a chemical burn?

Accepted Answer

Protect staff, remove contaminated clothing and jewelry, brush away visible dry chemicals, then irrigate promptly and copiously with water unless a substance-specific protocol directs otherwise. Do not attempt bedside acid-base neutralization because the reaction can generate additional heat and injury.

Question 35

How should trauma care preserve possible forensic evidence?

Accepted Answer

Treat life threats first and obtain consent when possible. Minimize unnecessary handling, document findings and statements objectively, package dry items separately in paper rather than plastic, label and seal them, and record every transfer to maintain chain of custody under the facility's forensic protocol.

Question 36

What is the purpose of the trauma primary survey?

Accepted Answer

Use a rapid <C>ABCDE sequence to find and treat immediate threats: catastrophic hemorrhage, airway with spinal protection, breathing, circulation, disability, and exposure with temperature control. Interventions and reassessment occur simultaneously; any deterioration restarts the primary survey.

Question 37

When does the trauma secondary survey begin?

Accepted Answer

Begin only after immediate primary-survey threats are addressed and resuscitation is underway. Perform a head-to-toe examination and obtain AMPLE history: Allergies, Medications, Past history or Pregnancy, Last meal, and Events or Environment surrounding the injury.

Question 38

What distinguishes damage-control resuscitation for major hemorrhage?

Accepted Answer

Control bleeding rapidly while minimizing crystalloid, using warmed whole blood or balanced components according to the major-hemorrhage protocol. Track temperature, coagulation, fibrinogen, ionized calcium, acid-base status, and response, then transition from fixed ratios to laboratory-guided therapy when possible.

Question 39

Why must ionized calcium be monitored during massive transfusion?

Accepted Answer

Citrate in blood products binds calcium; rapid transfusion can cause hypocalcemia, worsening hypotension, myocardial function, and coagulation. Monitor ionized calcium and ECG, and replace calcium promptly according to the massive-transfusion protocol rather than waiting for overt tetany or arrest.

Question 40

What is the trauma diamond of death?

Accepted Answer

Hypothermia, acidosis, coagulopathy, and hypocalcemia amplify one another during hemorrhagic shock. Break the cycle with rapid hemorrhage control, warmed blood-based resuscitation, temperature conservation, correction of calcium and coagulation deficits, and restoration of perfusion.

Question 41

What is the timing rule for tranexamic acid in bleeding trauma?

Accepted Answer

When protocol criteria for active or suspected major bleeding are met, give tranexamic acid as early as possible and no later than 3 hours after injury. Do not initiate it more than 3 hours after injury because late treatment may increase harm; follow the current trauma protocol for eligibility and dosing.

Question 42

Why is permissive hypotension not the default when traumatic brain injury dominates?

Accepted Answer

Restrictive pressure targets may limit bleeding before hemostasis, but inadequate pressure worsens cerebral ischemia. When significant TBI is the dominant problem, use a less restrictive strategy that preserves cerebral perfusion while pursuing hemorrhage control; individualize targets to the injury pattern and protocol.

Question 43

How do TRALI and TACO differ after transfusion?

Accepted Answer

Both can cause acute hypoxemia and bilateral pulmonary opacities. TRALI is noncardiogenic lung injury without circulatory overload; TACO reflects volume overload and more often includes hypertension, jugular venous distention, positive fluid balance, and improvement with diuresis. Stop the transfusion and initiate reaction protocol for either.

Question 44

What is the purpose of a trauma tertiary survey?

Accepted Answer

A deliberate repeat head-to-toe examination and review of imaging, laboratory results, procedures, and mechanism identifies injuries missed during resuscitation. Perform it after stabilization, commonly within 24 hours, and repeat focused examinations when the patient awakens, mobilizes, or reports new symptoms.

Question 45

What is the first response to new delirium after trauma?

Accepted Answer

Treat new delirium as acute organ dysfunction: repeat the primary survey, check glucose, perform a focused neurologic assessment, and evaluate hypoxemia, hypoperfusion, intracranial complications, infection, withdrawal, medications, pain, retention, constipation, and other metabolic causes. Pair cause-directed treatment with orientation, sleep protection, sensory aids, early mobility, hydration, and avoidance of unnecessary restraints or sedatives.

Question 46

What makes an interfacility trauma transfer safe?

Accepted Answer

Stabilize immediate airway, breathing, and hemorrhage threats without delaying definitive care for nonessential tests. Confirm acceptance, use direct clinician handoff, send imaging and records, secure tubes and lines, match transport capability to risk, and continue monitoring and resuscitation en route.

Question 47

What must trauma discharge readiness include?

Accepted Answer

Confirm safe mobility, pain and medication plans, wound or device care, equipment, transport, caregiver capacity, and follow-up. Give written return precautions for worsening breathing, bleeding, fever, neurologic change, uncontrolled pain, or device problems, using teach-back and language-access support.

Question 48

Why must mass-casualty triage be repeated?

Accepted Answer

Triage categories are temporary because physiology, resources, hazards, and treatment capacity change. Reassess after movement or intervention and as resources evolve; the goal is the greatest overall survival benefit, not first-come-first-served care.

Question 49

What closes the trauma performance-improvement loop?

Accepted Answer

Identify a case through registry data, audit filters, event reports, or outcome review; analyze contributing system factors; implement a measurable corrective action; then monitor whether compliance and outcomes improve. Education without documented follow-up does not complete the loop.

Question 50

What does EMTALA require when a trauma patient presents to an emergency department?

Accepted Answer

Provide an appropriate medical screening examination and stabilizing treatment within the hospital's capability, regardless of insurance or ability to pay. If needed care exceeds capability, arrange an appropriate transfer with acceptance, records, qualified transport, and treatment to reduce transfer risk.
