Final answer:
The action by the new RN that indicates the need for more education is increasing the FIO2 to 100% before suctioning.
Step-by-step explanation:
The action by the new RN that indicates the need for more education is a. The RN increases the FIO2 to 100% before suctioning. Suctioning should be performed with the lowest possible FIO2 to reduce the risk of hypoxia. Increasing the FIO2 to 100% before suctioning is not a recommended practice as it can lead to hyperoxygenation and can cause absorption atelectasis.
