Patient ratio while hanging chemo

Hi everyone, I was wondering what your patient ratio was for hanging chemo on an inpatient unit. I work on a med-surg Oncology unit, although most times it feels like detox unit. We are a 5:1 ratio on the floor pretty much at all times, which is awesome for overnight med-surg units). I was just wondering what the common ratio is and if having 4 other patients while hanging chemo sounds normal. Thank you!
