INTRODUCTION
This assessment is designed to prepare candidates for the NBRC TMC-CRT-RRT
examination by evaluating essential knowledge and clinical decision-making skills in
respiratory care. The exam includes multiple-choice and scenario-based questions that
reflect real-world clinical situations. It emphasizes patient assessment, therapeutic
interventions, ventilator management, and professional judgment. Candidates must
demonstrate the ability to interpret data, apply evidence-based practices, and ensure
patient safety. This testbank provides a comprehensive review of key topics while
reinforcing critical thinking necessary for competent respiratory care practice.
,SECTION 1: QUESTIONS 1–35
1. A patient presents with increased work of breathing and use of accessory muscles.
What is the most immediate action?
A. Obtain a chest X-ray
🔴 B. Administer supplemental oxygen
C. Perform pulmonary function testing
D. Schedule bronchoscopy
🔵 Explanation: Immediate oxygen support is critical to prevent hypoxia in patients
showing respiratory distress.
2. Which device delivers the most precise oxygen concentration?
A. Nasal cannula
B. Simple mask
🔴 C. Venturi mask
D. Non-rebreather mask
🔵 Explanation: Venturi masks provide controlled FiO₂ by using fixed air-entrainment
ratios.
, 3. A normal adult PaCO₂ range is:
A. 25–35 mmHg
🔴 B. 35–45 mmHg
C. 45–55 mmHg
D. 50–60 mmHg
🔵 Explanation: Normal PaCO₂ is 35–45 mmHg, reflecting proper ventilation.
4. What is the primary goal of PEEP in mechanical ventilation?
A. Increase CO₂ elimination
🔴 B. Prevent alveolar collapse
C. Reduce heart rate
D. Increase airway resistance
🔵 Explanation: PEEP maintains alveolar recruitment and improves oxygenation.
5. Which condition is characterized by decreased lung compliance?
A. Asthma
🔴 B. Pulmonary fibrosis
C. Bronchitis
D. Emphysema
🔵 Explanation: Fibrosis stiffens lung tissue, reducing compliance.
