About This Exam Preparation Resource
This 200-question practice test bank is designed to mirror the cognitive demand, clinical reasoning, and content
weighting of the National Board for Respiratory Care (NBRC) Therapist Multiple-Choice (TMC) Examination aligned
with the 2026-2027 content outline. Every question has been crafted to test respiratory care knowledge in the context
of realistic clinical scenarios that a Registered Respiratory Therapist (RRT) is likely to encounter in adult, pediatric,
and neonatal practice. Each question is paired with a verified correct answer and a detailed rationale that explains not
only why the correct choice is right but also why the distractors are incorrect.
The answer key is embedded directly beneath each question so that learners can receive immediate feedback. The
format reflects the "Verified Answers | Already Graded A+" standard: every correct option is marked [CORRECT],
and the rationale cites authoritative references including the AARC Clinical Practice Guidelines, the ARDSNet
Lung-Protective Ventilation Protocol, the GOLD COPD Report, the AHA ACLS Guidelines, the Surviving Sepsis
Campaign, the Brain Trauma Foundation guidelines, and current peer-reviewed literature.
How to Use This Resource Effectively
For maximum benefit, attempt each question by covering the answer key and rationale with a piece of paper. Read the
clinical stem carefully and identify the key data points: vital signs, ABG values, ventilator settings, medication doses,
or physical exam findings. Then select the BEST response from the four options before revealing the correct answer.
After checking your selection, read the rationale fully - even for questions you answered correctly. This ensures you
understand the pathophysiological reasoning, the guideline basis, and the patient safety considerations embedded in the
question.
Use this resource iteratively. On a first pass, focus on identifying your weak content areas and review the rationales
carefully for any question you missed or guessed. On a second pass timed to NBRC test conditions (approximately 1
minute per question for the actual credentialing exam), simulate exam conditions. For best results, complement this
resource with NBRC-published content outline documents and the AARC Clinical Practice Guidelines, which are
referenced throughout this test bank.
Cognitive Level Distribution
NBRC TMC questions are stratified by cognitive level to mirror the demands of clinical practice. The questions in this
bank follow the recommended distribution:
* Recall (30%): Direct facts, definitions, normal values, equipment specifications, and basic calculations.
* Application (50%): Application of knowledge to clinical scenarios, requiring interpretation of patient data and
selection of appropriate therapy.
* Analysis (20%): Higher-level analysis requiring synthesis of multiple data points, troubleshooting, and
prioritization of actions.

Section 1: Patient Assessment and Clinical Data Evaluation
History, Physical Exam, Vital Signs, and Laboratory Data (Q1-Q25)
Q1: A 68-year-old male with a 50-pack-year smoking history presents to the emergency department with
progressive dyspnea, productive cough, and bilateral wheezing. On inspection, the therapist notes a
barrel-shaped chest, use of accessory muscles, and cyanosis of the oral mucosa. Which of the following physical
examination findings is MOST consistent with severe hyperinflation secondary to COPD?
A. Increased tactile fremitus bilaterally
B. Dull percussion note in the upper lobes
C. Decreased breath sounds with prolonged expiratory phase [CORRECT]
D. Wheezing localized to the right lower lobe only
Correct Answer: C
Rationale: COPD with hyperinflation produces decreased breath sounds (due to air trapping and reduced airflow) and a
prolonged expiratory phase (due to airway obstruction and loss of elastic recoil). Tactile fremitus is decreased (not
increased) because hyperinflated lung tissue dampens sound transmission. Percussion is hyperresonant (not dull) due to
trapped air. Wheezing in COPD is typically bilateral rather than localized, so option D is incorrect.
Q2: While palpating the chest of a patient admitted with suspected left-sided pneumothorax, the respiratory
therapist notes absent tactile fremitus over the left anterior chest and tracheal deviation to the right. Which of
the following is the MOST appropriate interpretation?
A. Left-sided pleural effusion causing mediastinal shift
B. Left-sided pneumothorax causing tension physiology [CORRECT]
C. Consolidation of the left upper lobe
D. Atelectasis of the right lung with compensatory hyperinflation
Correct Answer: B
Rationale: Absent tactile fremitus over the affected side suggests air (pneumothorax) or fluid in the pleural space rather than
solid lung tissue. Tracheal deviation to the contralateral side (right) indicates a tension pneumothorax on the left, where
accumulated intrapleural air pushes mediastinal structures away from the affected side. Pleural effusion typically dulls
percussion and reduces fremitus but causes contralateral tracheal deviation only when massive. Consolidation increases
fremitus; atelectasis on the right would shift the trachea to the left.
Q3: A therapist is performing percussion on a patient with suspected pleural effusion. Which percussion note
would the therapist MOST likely elicit over the area of fluid accumulation?
A. Resonant
B. Hyperresonant
C. Dull [CORRECT]
D. Tympanic
Correct Answer: C
Rationale: Pleural fluid is dense and transmits sound poorly, producing a dull percussion note (similar to percussion over
the liver or heart). Resonant and hyperresonant notes indicate normal or increased air content (as in emphysema or
pneumothorax). Tympanic notes are elicited over gas-filled viscera such as the stomach. The AARC Clinical Practice
Guideline on thoracentesis emphasizes ultrasound confirmation when dullness suggests effusion greater than 200 mL on
physical exam.
