Therapist Multiple-Choice (TMC) Examination. Pass the
high-cut score for Clinical Simulation eligibility.
✔ Core TMC Domains Covered
✔ Detailed Clinical Rationales
✔ ABG, Vent Management, Pharmacology

Prepared for 2026 Examination Standards | Professional Review Guide
,INSTRUCTIONS & STUDY METHODOLOGY
How to use this study guide:
This exam-preparation document simulates the difficulty and structural format of the
actual NBRC TMC examination. The questions are designed to test your critical thinking,
diagnostic capability, and clinical management skills as a Respiratory Therapist.
Analyze the data: Always evaluate the patient's presentation, vitals, and ABGs
before reading the options.
Identify the exact problem: Are you treating oxygenation (PaO2) or ventilation
(PaCO2)?
Review the Rationales: The rationales provided in Green are critical for your
understanding. Even if you answer a question correctly, read the rationale to
understand why the other distractors are incorrect.
, PRACTICE EXAMINATION
Question 1
A 65-year-old male with a history of severe COPD is admitted to the Emergency
Department with shortness of breath and confusion. His arterial blood gas on
room air shows: pH 7.25, PaCO2 68 torr, PaO2 45 torr, HCO3 32 mEq/L. Which
of the following is the most appropriate initial intervention?
A. Intubation and mechanical ventilation
B. Noninvasive positive pressure ventilation (NPPV)
C. Oxygen via nasal cannula at 6 L/min
D. Administer an albuterol treatment
Correct Answer: B. Noninvasive positive pressure ventilation (NPPV)
Rationale: The patient is experiencing an acute-on-chronic respiratory acidosis.
NPPV is the standard of care and first-line treatment for COPD exacerbations with a
pH between 7.25 and 7.35. It decreases work of breathing and improves alveolar
ventilation without the risks associated with invasive intubation.
