It is veeeery overwhelming. I should know, as my unit is the exact same way most nights. I've seen everything from acute MIs to GI bleeds to unresponsive SVT, you name it; we've had it! The key is they are trying to make your unit a step-down unit. That's why you are seeing an increase in patient acuity level. But you have every right to be overwhelmed, and you should speak up about it. Mind you that most ICU nurses can only have a maximum of 2 patients with the acuity level that your patients have; on any other floor (well at least on ours) the max is 6 patients. I really think you should have a serious discussion with your director about how these working conditions can negatively affect patient outcome in the long run. Safety is of utmost importance (in my mind), so a nurse with only 1 and 1/4 years experience as the most experienced nurse on the shift raises a red flag.
