Free RRT Practice Questions
Five original questions with explanations
These are original educational questions written to exercise RRT-relevant reasoning. They are not recalled examination items and do not imply access to confidential test content.
Question 1
A ventilated patient’s peak pressure rises while plateau pressure is unchanged. What problem is most likely?
- A. Increased airway resistance
- B. Reduced chest-wall compliance
- C. Improved ventilation
- D. Circuit disconnection with no alarm
Answer and explanation
A. Increased airway resistance A rise in peak but not plateau pressure points toward increased airway resistance.
Question 2
An arterial blood gas shows acidemia with elevated carbon dioxide. Which primary disorder fits?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic alkalosis
- D. Normal compensation
Answer and explanation
A. Respiratory acidosis Elevated carbon dioxide with acidemia indicates a primary respiratory acidosis.
Question 3
A pulse oximeter reading conflicts with the patient’s appearance. What is the best response?
- A. Treat the number only
- B. Assess the patient and verify signal quality and perfusion
- C. Ignore both
- D. Replace documentation
Answer and explanation
B. Assess the patient and verify signal quality and perfusion Clinical assessment and signal verification are necessary when measurements conflict.
Question 4
Which change can improve oxygenation in appropriately selected severe dependent lung disease?
- A. Prone positioning
- B. Removing all PEEP
- C. Shortening exhalation in obstruction
- D. Ignoring secretion burden
Answer and explanation
A. Prone positioning Prone positioning can improve ventilation-perfusion matching in selected patients.
Question 5
Why is equipment calibration and quality control documented?
- A. Marketing
- B. Measurement validity, safety, and traceability
- C. To replace assessment
- D. To guarantee a diagnosis
Answer and explanation
B. Measurement validity, safety, and traceability Quality control supports reliable measurement and traceable corrective action.
