If resting FiO2 requirement increases as a result of exercise session, communicate to medical team.

• A. stays the same
• B. decreases
• C. varies
• D. increases

Answer: (D)

When the resting FiO2 requirement increases after an exercise session, the best action is to communicate that the patient now needs more oxygen at rest. This signals the team to re-evaluate and adjust the oxygen prescription so we can maintain the target oxygen saturation. Exercise can reveal or worsen desaturation due to increased oxygen demand and possible inefficiencies in gas exchange, so an increase in FiO2 at rest means a change in the patient’s oxygen needs rather than no change or a decrease. After reporting this, monitor the patient’s SpO2 at rest and during activities, and adjust the oxygen delivery accordingly to achieve the target range.
