You will not be expected to be an ICU nurse and have all the answers when you enter this clinical. You will be expected to look up and ask a lot of questions. Things to look up before you start: VAP prevention, CLABSI prevention, CAUTI prevention, ABGs, Vasopressors (Epi, Levo, Vaso, Neo, etc), Sepsis and treatment bundles. Know your cardiac meds: Beta blockers, Nitro, Amio, etc. Look at proton pump inhibitors, Look at heparin, heparin gtts and protocols and insulins. I found that using a sheet of paper with each body system will help with report, as ICU report is more in depth into each body system than med surg.
Mine looks like this:
Keep organized and you will be fine. Ask a lot of questions. Be prepared for clinical and you will be fine. Good Luck!
