I work on a stepdown/floor unit, so our ratios vary depending on the # of stepdown pts... On day shift you can be 3 pt's/1 RN (with 2 SD pts), 4:1 (1 SD). On rare low-staffing occasions we may get 5 on day shift. On night shift we do 4:1 (2 SD) or 5:1 (1 SD). We have 2 CNA's for our floor, 16 pts to each of them, and 1 full-time secretary. We also have a free float charge RN on day shift and on night shift the CN has 1-2 pts.
