10 weeks does not seem long enough!
As a new grad I had 6 months! It was broken into three phases, phase 1 (feeders/growers, stable admits, bili lights, nasal cannula/vapotherm etc). Phase two (stable vents, cpap/sipap, stable post-ops etc). Phase three (HFOV, ECMO, cooling, sick admits, bedside surgeries, sick micro's, pphn, pressors, nitric etc). I think the way my orientation was done was great, we were introduced to new concepts slowly and slowly advanced our skills. For the first month or so off orientation we had a resource person assigned to us as well who generally had a fairly light assignment so they could be there to answer our questions.
Now as an experienced nurse, when I transferred to the peds cicu I had a 4 month orientation, now I had experience in this unit already as a float nurse but that was the standard orientation for experienced nurses.
In both situations I think 10 weeks is not enough.
