I started as a new grad on a burn unit in 2013. I work at a level 1 adult/ped trauma center teaching hospital with a children's hospital (so peds burns go there, not to my unit). My unit is very small, but we're classified as an ICU/stepdown unit and we try to keep our burn patients until they're ready for discharge. However, hospital needs sometimes dictate that we have non-burn patients, and sometimes our burn patients get moved to the med-surg floors when medically ready. Nurses from my unit don't follow them, but the same MD team does. (It's actually pretty rare for us to have *only* burn patients on the unit.)
As 'awilliamesu' says, it would be easier to answer burn-specific questions than just give you a wall of text! However, here is a different wall of text: Any new job has a lot of things to get used to--
-Make sure you're looking up policies during your orientation. At my hospital, almost everything has a policy or procedure! Want to know how much tube feed to give back to a pt when checking a residual vs. when to hold the feeding? Check the procedure. Want to know how to titrate your insulin gtt for hyperglycemia? Check the procedure. Want to know what order to draw your labs in? Check the procedure. How long can a femoral trauma line stay in place? Check the policy. Not just clinical stuff-- When and under what circumstances can you float to another floor? Check the policy. How and when can you pick vacation time? Check the policy....you get the idea. Your preceptor is (hopefully) a great resource but they are not infallible; pull the policy to be sure you've covered everything.
-Try to understand the organizational system of your workplace. Since I'm at a teaching hospital, there's a hierarchy of MDs I can call with concerns about a patient. There is no bigger waste of time than paging someone only to have them finally call back to discover they're not covering your patient anyway! On the nursing side of things, learn what your resources are: There's hopefully a charge nurse on your unit, then maybe a unit manager? Maybe you have SWAT or some other team of 'emergency' nurses who help with codes? There is probably a nursing administrator who manages staffing and bed-placement (if you're part of a larger hospital), as well as helping resolve difficult situations with a patient or family.
-Learn what the other clinical teams (RT, PT, OT, speech, dietary) do and how they can help your patient. If your patient needs a swallow evaluation, try to schedule it with the speech therapist when you & PT/OT are going to be getting them up into a chair anyway (as an example).
-Figure out how to use the phone. Transferring calls from our phones takes about 8 buttons! (We also have Voceras that we all wear...) Get comfortable talking on the phone, using SBAR format ("I'm calling about Ms. Jones of Surgery1 who had a small bowel resection on the 12th; her HR is 120 and her BP is 90/50, she's not complaining of any pain, her IV fluids are running at 100mL an hour but her urine output has declined the last 3 hours from about 80 an hour to 25 this last hour, etc...). I work nights, so the 2 residents who cover the surgery teams cover ALL the surgery teams. They don't actually know the patients well. This may not be an issue for you if your MDs only handle burns, but being concise still helps! Learn what your institution's policy is about giving out pt info over the phone. Burns are often in the local news, and you never know who is calling to check on them.
-Try to figure out what *you* need to do to be comfortable and gain confidence. As much as possible, sign up for extra training and hands-on practice sessions if they're available. Get enough sleep, don't go crazy with picking up OT, eat right, etc... Get to work on time and be ready to work. You will meet people who don't do any of these things. You may have opinions about these people...keep them to yourself!
I do check this forum occasionally and will try to answer burn questions if you post them. Good luck with your new position!
