b. Document these findings in the chart.
c. Immediately increase the flow rate.
d. Turn the flow rate down to 2 L/min.

For the Venturi mask to deliver high flow of oxygen, the flow rate must be set correctly, usually between 4 and 10 L/min. The client's flow rate is too low and the nurse should increase it. After increasing the flow rate, the nurse assesses the oxygen saturation and documents the findings.
