Oxygen Therapy — Quiz

Test your understanding of oxygen therapy with 5 practice questions.

Practice Questions

Question 1

A patient with severe acute respiratory distress syndrome (ARDS) requires mechanical ventilation and high $F_iO_2$. Which of the following best describes the primary mechanism by which oxygen therapy benefits this patient, beyond simply increasing arterial oxygen content?

Question 2

A paramedic is managing a patient with suspected tension pneumothorax. After needle decompression, the patient's respiratory status improves, but they remain hypoxic. What is the most appropriate next step in oxygen therapy management?

Question 3

A patient with a history of chronic bronchitis presents with acute exacerbation and an $SpO_2$ of 88\% on room air. The paramedic initiates oxygen therapy. What is the most critical parameter to monitor closely during oxygen titration in this patient?

Question 4

A paramedic is called to a patient with a severe asthma attack. The patient is in significant respiratory distress with an $SpO_2$ of 90\% on room air. Which oxygen delivery device and titration strategy is most appropriate for initial management?

Question 5

A patient with a traumatic brain injury (TBI) is being transported. The paramedic notes an $SpO_2$ of 92\%. What is the most appropriate oxygen titration strategy for this patient, considering the potential for secondary brain injury?
