We also float to peds/picu in low census. We only care for under 2 years. We have a resource and we always refuse unsafe assignments, we don't do admissions there either. It is difficult to step onto another unit with different routines and practices but like others noted, you have to think about what a prudent nurse would do. As for infection control, we have peds/ picu floats often and we haven't had any issues but several of us have got upper respiratory issues after floating there. On a side note, we were floating to med surg and Ed as "helpers" where we could only assist nurses and techs, run to pharmacy and lab, take vitals (then report to rn). That was a challenge because we had to argue the safety of our ability levels in adults and why we couldn't accept assignments on an overwhelmed, understaffed floor. Bottom line: floating is uncomfortable but necessary evil sometimes.
