Read the first 7 Specialty Credentials flashcards as text

  1. An RT who earned only the CRT credential wants to obtain the RRT-NPS. What must they do first?

    Answer: Earn the RRT credential before applying for any specialty credential

    All NBRC specialty credentials (NPS, ACCS, SDS) require an active RRT as a prerequisite; the CRT alone is insufficient.

  2. On the CPFT examination, which of the following measurement techniques would a candidate most need to understand?

    Answer: Body plethysmography for measuring functional residual capacity

    Body plethysmography is a key pulmonary function testing method for accurately measuring lung volumes including FRC, making it central to the CPFT examination.

  3. An RRT-ACCS credentialed therapist is managing a patient on ECMO. Recognizing this as an advanced critical care modality, this topic would most likely appear on which NBRC examination?

    Answer: RRT-ACCS examination

    ECMO in adult critically ill patients falls within the advanced adult critical care scope that the ACCS credential and examination address.

  4. The NBRC defines 'credential lapse' as occurring when:

    Answer: A credential holder fails to complete Continuing Competency requirements by the expiration date

    Credential lapse is the automatic loss of credential status that occurs when the 5-year Continuing Competency deadline passes without fulfillment.

  5. Which pulmonary function test result pattern would an RPFT-credentialed technologist most associate with a restrictive lung defect?

    Answer: Reduced TLC with normal or elevated FEV1/FVC ratio

    Restriction is characterized by a reduced total lung capacity (TLC) while the FEV1/FVC ratio is preserved or elevated due to proportional reductions in both values.

  6. A sleep study scorer preparing for the RRT-SDS examination should know that hypopnea is scored when airflow decreases by at least:

    Answer: 30% from baseline with associated 3% oxygen desaturation or arousal

    Per AASM scoring rules, a hypopnea requires ≥30% airflow reduction from baseline plus either ≥3% oxygen desaturation or an arousal.

  7. What is the primary advantage of the NBRC credential verification system for employers?

    Answer: It allows employers to confirm an RT's current credential status and expiration date online

    The NBRC online registry lets employers verify whether a respiratory therapist currently holds an active credential and when it expires.
