NBRC Specialty Credentials 4 — Questions and Answers
Question 1: An RT who earned only the CRT credential wants to obtain the RRT-NPS. What must they do first?
- Earn the RRT credential before applying for any specialty credential (Correct answer)
- Apply directly for the NPS examination regardless of CRT status
- Complete 2 years of NICU experience to waive the RRT requirement
- Petition the NBRC for a credential equivalency review
Correct 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.
Question 2: On the CPFT examination, which of the following measurement techniques would a candidate most need to understand?
- Body plethysmography for measuring functional residual capacity (Correct answer)
- Transcutaneous CO2 monitoring in neonates
- Polysomnography electrode placement
- Arterial line insertion technique
Correct 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.
Question 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?
- RRT-ACCS examination (Correct answer)
- CPFT examination
- NPS examination only
- CRT entry-level examination
Correct 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.
Question 4: The NBRC defines 'credential lapse' as occurring when:
- A credential holder fails to complete Continuing Competency requirements by the expiration date (Correct answer)
- A credential holder voluntarily surrenders the credential
- A credential holder is found to have cheated on an examination
- A credential holder moves to a state that does not require licensure
Correct 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.
Question 5: Which pulmonary function test result pattern would an RPFT-credentialed technologist most associate with a restrictive lung defect?
- Reduced TLC with normal or elevated FEV1/FVC ratio (Correct answer)
- Reduced FEV1/FVC ratio with normal TLC
- Elevated RV with air trapping on the flow-volume loop
- Normal spirometry with reduced DLCO only
Correct 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.
Question 6: A sleep study scorer preparing for the RRT-SDS examination should know that hypopnea is scored when airflow decreases by at least:
- 30% from baseline with associated 3% oxygen desaturation or arousal (Correct answer)
- 10% from baseline with any desaturation
- 50% from baseline with 5% desaturation
- 20% from baseline with an arousal only
Correct 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.
Question 7: What is the primary advantage of the NBRC credential verification system for employers?
- It allows employers to confirm an RT's current credential status and expiration date online (Correct answer)
- It provides full examination score reports to employers
- It automatically notifies employers when an employee's credential lapses
- It lists disciplinary actions taken against all credential holders
Correct 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.
