Free RT (CRT/RRT) Exam Flashcards

NBRC describes the Therapist Multiple-Choice (TMC) exam as 160 multiple-choice items.

The current TMC blueprint uses 140 scored items and 20 pretest items mixed into the exam.

NBRC lists the TMC appointment as 3 hours.

NBRC lists the Clinical Simulation Examination (CSE) at 22 problems (20 scored + 2 pretest) with a 4-hour time limit.

NBRC posts TMC fees at $190 for new applicants and $150 for repeat applicants.

NBRC lists the CSE fee at $200 for both new and repeat applicants.

At the low cut score, candidates earn CRT. At the high cut score, candidates earn CRT and become eligible for the CSE in the current pathway.

NBRC states the current TMC detailed content outline remains effective through December 31, 2026.

NBRC has published a transition to a single RT Examination in January 2027 with 185 total items (160 scored + 25 pretest).

NBRC states CSE remains available through December 31, 2027 for candidates who met TMC high-cut eligibility by December 31, 2026.

The TMC detailed content outline assigns 50 scored items to Patient Data Evaluation and Recommendations.

Start ABG interpretation with pH, then map the primary change in PaCO2 or HCO3 to identify likely respiratory vs metabolic disturbance.

PaO2 and oxygen saturation trends reflect oxygenation status, while PaCO2 trends reflect ventilatory adequacy.

RT exam items often reward trend analysis over single values: compare serial ABGs, vital signs, and clinical findings before intervening.

A widened A-a gradient supports gas-exchange impairment rather than pure hypoventilation and can change your differential.

The PaO2/FiO2 ratio is a rapid severity marker for oxygenation impairment and helps prioritize escalation decisions.

End-tidal CO2 trends can help track ventilation changes quickly and should be interpreted with patient context and waveform quality.

Use chest-imaging findings with auscultation, work of breathing, and blood-gas data to avoid single-source decision errors.

Respiratory interventions should be selected with blood pressure, perfusion signs, and cardiac status in mind, especially in unstable patients.

When data suggests rapid deterioration, escalate promptly and prioritize airway, oxygenation, and ventilation stabilization.

The TMC outline allocates 20 scored items to Troubleshooting, Quality Control, and Infection Control.

Common causes include secretions, bronchospasm, biting, water in tubing, or decreased compliance; check patient factors first, then circuit/equipment.

Low-pressure alarms often indicate leaks or disconnections in the circuit, cuff leak, or loose connections.

Confirm tube position and cuff integrity, inspect the circuit for leaks, then reassess patient effort and synchrony.

Calibrate and verify oxygen analyzers per manufacturer instructions and department policy before clinical use.

Poor perfusion, motion, nail products, and sensor-placement issues can create inaccurate SpO2 readings.

Use facility-required PPE and source-control steps for aerosol-generating procedures to reduce transmission risk.

Inadequate humidification can worsen secretion burden and airway injury risk in patients with artificial airways.

Pre-use checks should confirm power/gas source, alarm function, circuit integrity, and ordered settings before patient connection.

After equipment-related events, document findings, corrective actions, and patient response clearly for quality and safety follow-up.

The largest TMC domain is Initiation and Modification of Interventions with 70 scored items.

Escalate oxygen support when targets are not met, balancing oxygenation goals with risk of over-oxygenation in susceptible populations.

Noninvasive ventilation is generally considered when ventilatory support is needed and airway protection/mental status are still adequate.

Escalate to invasive support when noninvasive strategies fail or when airway protection and gas exchange cannot be maintained safely.

Ventilator adjustments that increase effective minute ventilation can reduce elevated PaCO2 when clinically appropriate.

Weaning decisions require stable oxygenation, manageable work of breathing, hemodynamic tolerance, and acceptable mental status.

Choose MDI, DPI, or nebulized delivery based on patient ability, airway status, device technique, and urgency.

Match airway-clearance methods to secretion burden, patient tolerance, and contraindications rather than using one method for all cases.

High-risk patients may need planned support and close reassessment immediately after extubation to prevent avoidable failure.

During resuscitation, respiratory therapists support airway management, ventilation quality, oxygen delivery, and continuous reassessment.

A practical TMC weighting is Interventions first (70 items), Patient Data second (50), and Troubleshooting/QC/Infection Control third (20).

At 180 minutes for 160 items, pacing is about 68 seconds per question. Avoid spending too long on a single item.

When choices seem close, prioritize the option that secures airway/oxygenation/ventilation safety before lower-priority actions.

Use a consistent triage order: immediate airway and breathing threats, then oxygenation/ventilation adequacy, then diagnostics and optimization.

Large simultaneous setting changes can create secondary instability; adjust deliberately and reassess response after each change.

NBRC policy states no waiting period for the first three attempts, then a 120-day wait period applies after the third unsuccessful attempt.

CSE problems evaluate stepwise clinical judgment across evolving scenarios, so sequence and appropriateness of choices matter.

Clear, concise handoffs and objective documentation support continuity of care and reduce preventable respiratory-management errors.

Before test day, confirm authorization, accepted ID, travel buffer, and any testing-center procedural requirements.

Rotate study guide review, timed practice questions, and flashcards to improve both concept depth and decision speed.
