The secretary of the building I went to my first day showed me where to find keys and standing orders/policies and verbalized a few that she knew and impacted her job like sending kids home and excluding kids. Then, an hour or so later, a CSN came and showed me the charting system and how to handle incoming paperwork. What to enter, what to pile, what to file. She sat with me for the morning, as a resource, while doing CSN reports and other tasks on her computer. After that, when I went to a different building, a secretary gave me keys and I found the rest. Every nurse has a different lay out of treatment supplies and binders of info.
