Sounds scary to me too! I do per diem work on a busy heme/onc medical floor (with lots of surgical patients thrown in) for a large teaching hospital. The patient/nurse ratio is very rarely greater than 6:1. . . and that's with a full compliment of support staff!
Now. . . my full-time job is on a small ICU/CCU for a small community hospital. The patient nurse ratio is very rarely greater than 2:1. And most of these patients are "rule outs"!
I'd run away faster than SVT too!
