As a fairly new grad (8 months in) I am working in PCU, I had 12 weeks of unit orientation, I couldn't imagine doing 8 weeks. I also was always asking questions about things I was unfamiliar with. I didn't just ask my preceptor, I would ask my co-workers as well. I would ask about certain tasks I performed only once, or just to ensure my train of thought was correct re. certain things. I sometimes didn't sit down until 1am to start charting. Other times it was before midnight. Sometimes meds are late, but not so much, and hour maybe. But that was because I had to focus on other aspects of care that required my attention. There are some things that are higher on the totem pole, and I learned quickly that charting is not one of them. I hope things look up for you and there is a chance for you to transfer to a lower acuity unit.
