picu troubles??

Hello all you fellow RNs!!

I have been acquiring info from this site for weeks now and have finally decided to join the ranks!! So here we go... I am a new grad removed, which basically means that I graduated from nursing school in mid '08 then from personal, social, and whatever other issues I was having at the time, did not start working as a RN till December '08. I am always, always up for a good challenge and like the kiddies, so I decided for a possible career in the PICU. I can tell you sometimes I feel like I bit off more than I could and can chew!! I am in my 16 week of a 6 month orientation and in my aspect, things are coming along as they should for my situation, but to my educating coordinators, I am not progressing along as I should be... This truly, truly breaks not only my heart, spirit, and confidence as a new RN, but fortunately, my "angel on earth" preceptor. I have decided (for the time being until I can't take it anymore) to stay in the PICU and fight my way through... I know and feel things will come together in time, place, and space with a little help from my friend here...
I need some major help w/ :stopcocks and which way to turn the stupid things, drawing blood from both the artline where the VIA maching is attached- waste or not to waste, when to waste, how to waste, etc,, drawing venous blood gases off of central line where CVP monitoring is attached, thats all I can think of for now till next time. I feel sooo dumb for asking these things... I think I got it, but when I do these things I just seem to fumble this up and it is soooo not good for me at this point in time since I'm under such heavy scrutiny!

Thanks so much!!!
