NBRC Specialty Credentials 5

Question 1

An NPS-credentialed RT is assessing a 28-week premature infant with increasing FiO2 requirements on nasal CPAP. The next most appropriate escalation step is:

Accepted Answer

Intubation and administration of exogenous surfactant

Answer

Premature infants with respiratory distress syndrome who fail CPAP require intubation and surfactant replacement therapy as the next escalation step.

Question 2

The NBRC Therapist Multiple-Choice (TMC) examination is a prerequisite for which credential pathway?

Accepted Answer

Both the CRT and RRT credentials require passing the TMC

Answer

All entry and advanced credential candidates must pass the TMC; CRT is awarded at a lower cut score and RRT requires both a higher TMC score and passing the CSE.

Question 3

Which of the following clinical competencies is unique to the RRT-SDS examination blueprint and would NOT appear on the ACCS examination?

Accepted Answer

Scoring polysomnography respiratory events using AASM criteria

Answer

Polysomnography scoring using AASM criteria is a sleep-specific skill that belongs exclusively to the SDS examination scope.

Question 4

When interpreting a DLCO result, an RPFT-credentialed technologist knows that a significantly reduced DLCO with normal spirometry most commonly suggests:

Accepted Answer

Pulmonary vascular disease or early interstitial lung disease

Answer

Isolated DLCO reduction with normal spirometry indicates impaired gas exchange at the alveolar-capillary membrane, characteristic of pulmonary vascular or early interstitial disease.

Question 5

An RT preparing for the RRT-ACCS examination reviews ventilator-induced lung injury (VILI). Which protective ventilation strategy is most strongly supported by evidence for ARDS patients?

Accepted Answer

Tidal volumes of 6 mL/kg IBW with plateau pressure <30 cmH2O

Answer

The ARDSNet protocol of 6 mL/kg IBW with plateau pressure limitation to <30 cmH2O is the cornerstone evidence-based lung-protective strategy for ARDS.
