Why not try 8-hour shifts instead of twelves, just for orientation? It would give you slightly more exposure to different types of surgical pt's. What is on your skils check list? Is there a list of skills/types of pt's you have to get "checked off" on? If so, and you aren't done at the end of your time, then there is good documentation to extend your orientation.
Grouchy, take a deep breath! You are nervous, and that is GOOD! If you weren't nervous about doing something new, and concerned about how well you will do, I'd be way more worried about you. You will NOT learn everything in a week, four weeks, four months, or a year!! You can only possibly learn the basics in an orientation. Think of all you have going for you, you can read monitors!! Can I tell you how much harder it was for me when I started out in ICU w/ NO monitor experience. I was scared $hitless!! And I wasn't enrolled in the "ICU Course" for six months, it was only given every 6 months! So, when a vent went off, if it wasn't obvious, I just ambu'd and yelled for help! Once I ran with the defibrillator into a pt's room, only to find him brushing his teeth! I was NOT a new grad!!
I am not trying to make light of your concerns, only saying, give yourself a little slack, see how it's going midway through, set some goals, what do YOU think you need to learn MOST before orientation ends? What are you weaknesses; focus your orientation on getting answers to those questions. Buy a good ICU hanbook, and keep it with you at all times. Flip it open and skim the contents if you have to. Find out who the smartest people in the unit are. Which docs, crna's anesthesiologists, etc, like to teach? Pepper them with questions. When you get report, ask before sign-off, is there anything I should watch for particularly with this pt? Make cheater index cards, like steps in drawing labs off an a-line if you have to. Get a small spiral notebook that will fit in your pocket, if you have no pockets, get a new pair of scrubs
with as many posckets as possible. Write all important ditty's you need to remember in the notebook, soon you won't need it, but you will feel secure knowing it's there. I typed out and shrunk up and pasted the instructions for CVVH into my little notebook, computer codes, everyone's little notebook should look different, whatever works for YOU!
You will be great, you can DO IT!!! Now go look in the mirror, and tell yourself that, and tell yourself that q morning of orientation.
