Shadowing happens all the time here. There is even a program for high school students interested in nursing to shadow a nurse. A few begining nursing students have also shadowed.
(Once they are hired, they work with another nurse, a preceptor to guide them along.)
The "shadows" have brief orientation regarding emergency codes and protocol, and regarding confidentiality, then they tag along. We make it clear that if it gets really busy, we may not have time to explain what we are doing and why, so just watch and ask questions later.
We only have shadows for nurses who like and want them. So far it has gone over very well with the community and with the staff. It's kind of fun to show off what I love to do,..... and having someone looking over my shoulder keeps me sharp!
Best of luck to you Maria!!!
