I'm on a med-surg floor, night shift, and we're 8 patients each lately, although 7 is the norm. Day and evening shift lately have been six, although five is usual when the census isn't quite as high. I've had some overwhelming shifts recently, lots of precaution patients, blood administrations, Q2 CIWAs and pain meds- it's been challenging for sure, and I don't really think that it's safe.
I did a double the other day and that day shift with six kicked my butt!!
