I am on a Telemetry/medicine unit (although we are primarily cardiac). On days and evenings we are at a 5-6:1 ratio with 4-6 NA. 2 monitors. We do not titrate drips based on protocols EXCEPT for Heparin drips, although we do have patients on Cardizem, Amio, Milrinone, Lasix, Integrilin, etc. They are stable, and titration based on protocol is not necessary, except for weight based changes.
Our PCU has a ratio of 4:1 and they do titrate and also have electrolyte replacement orders that they do. Our ICU has an ideal ratio of 2:1, with the occasional 3:1, and they also have their own monitor, MD, and do lots more with drip titration, etc, than any other unit.
Having floated to PCU and tasked in our ICU, I could not imagine having 7 patients with high risk drips that you need to titrate. I would be scared for my sanity (and my license!). I have been on my unit since I graduated last year, and still have days when I can't keep up, and we are a less acute unit.
Hopefully you have a good staff to go to for help, and if you don't consider a medsurg floor for a while to get your feet wet with less high risk patients.
