I'm having a really stupid brain block here.I'm about a week to coming off of orientation. I work in an IMC, since we can get pulled to the ICU, I'm with a preceptor for that unit now. I give you the background so you can imagine the more important info coming at me at warp speed!Further background, I work with an awesome team. My preceptors have been great, my NM is very supportive of me. Everyone says I expect more of myself than what they are expecting and my NM even has complimented my intelligence and where I'm at so far. However she can see I'm not believing it myself (why would I, I'm new?!)However I'm feeling like common sense is out the window with me and I've always struggled with mechanical things. I'm being told I'm thinking about things too much when it's more of a "go with it and trust instincts" type thing. Here's what I got so far and maybe someone can help make this click. (or maybe it is just practice, practice) we have the alaris pumps for reference and they are great compared to the baxter, but I never got real experience w/those either.I understand hanging multiple things on different channels and differrent ports on picc's (good, right ) I got the IVPB if you have some type of maintence running and you want to infuse say a run of k. I've now learned if you need to give an IV push you can go to a port closest to pt and do a push and pinch method. I understand the y-port method if you can't stop the primary and IVPB and that's closest to pt (and other ports are taken)I figure in another month I will be kicking myself for not getting this but right now it's driving me nuts! I thought I was okay with all of the above then yesterday I walked in and the pt had a picc with all ports already taken, plus was running a fentanyl which I now see that will also have a smaller bag of fluid to push the fentanyl through and seperate y tubing!I had to do a run of k and since they were already running lasix, and propofol, along with the fentanyl it threw me! I ran a compatibility check (gotta love the computerized ck for that) on all and one came up questionable. So I had no idea if any of that could be paused for a IVPB or what. I think we ended up PB'ing it but I can't remember to what...yest was a whirlwind!I can't stand that I can't go into a room with various infusions and need to add something and know what to do, it's like I go stupified or something and I don't know if it's the pressure of all the other things I'm learning or what. And it's only going to get more intense as we often get cardiac as well as heparin drips. I did have a pt on a heparin and a nitro drip but she only had those 2 things going and other than balancing out the titration...that was okay.And I have gone to my preceptors, co-workers with this, I'm not standing there like "yeah I get it" and I'm afraid to tell them, I TELL them I am absolutely stupid on this and they smile and say "it'll come with time/practice"...Really? Did any of you struggle with basics like this? Oh and just when I thought *maybe* I'd have enough info to muddle through because I'm figuring okay IVPB the port before the pump got it...y-porting ...the one closest to the pt....but what about the port right below the pump? Well my preceptor said she's never really used it...I said "good...good enough for me, don't need to know right now" ...then she says....well, you could hook up another compatible fluid there if you didn't have anywhere else to go! Nooooo I didn't want to hear that! I wanted her to stay with "you'll never use that port!" Lastly, do I have it right with incompatible and picc lines you can just choose one of the compatible alternative and it's okay to run b/c the picc line port exit at different points in the SVC? I always thought if it was incompatible you couldn't run it even through a different port.Thank you for any perspective. I now understand why they say when you're new you go home and cry and it's not necessarily from being yelled at or mistakes. It can be b/c I'm so frustrated with not getting it and wondering if they made a mistake putting a RN behind my name.
