Your scope as a PCT is different from my scope as an NT, because I can do foleys, blood draws, dressing changes (both sterile and non-sterile!), start IVs, even give enemas! (thankfully that experience hasn't presented itself yet
but I don't want to be the nurse who has never and doesn't know how to give an enema!)
Anyway, I have an assigned unit, but I do pick up and float throughout my hospital. I've floated to other med-surg units, telemetry, the ICU and ICU stepdown. Most of them are the same but the ICU/ICU stepdown units are a little different.
I typically work 3-11p, occasionally 3p-3a and I also work 11p-7a. I rarely work at 7a, mainly because I'm not really a morning person. Anyway, my typical 3-11p shift:
3pm: get report, start vitals. I only do Q4's.
4pm: put in vitals (oftentimes I'm done before 4pm, but not always)
4pm: get blood sugars on patients who need them
5pm-6pm: basically help the nurses/patients with whatever they need and answer call lights.
6:45-7pm: start vitals. This is when the Q12's need to be done, too (those are done once/shift, so at 7am and then again at 7pm)
8pm: put in vitals...I also take my break at this time
9pm: get HS (bedtime) blood sugars on patients who need them.
10pm-11pm: again, just help then nurses/patients with whatever they need and answer call lights. At 11pm I give report to the oncoming aide/tech.
If blood needs to be drawn, I will do that...same with dressing changes, foleys, etc. If patients are being discharged, sometimes they will have me wheel them downstairs to their destination. If patients are being transferred to different units, sometimes they will have me bring patient belongings to their new room or help transport the patient over to their new room. Sometimes they will have me go down to the lab to drop off blood cultures (because those are glass bottles and can't be tubed down to the lab, too much risk of them breaking) and also to stock up on blood culture bottles. I will also be sent to other units to get things, such as a bladder scanner or other supplies. If we have sitter cases that can't be covered, then I am the one who has to cover them, either on my floor or I will get sent to the floor that needs me.
Here is my typical 3-11p day on the ICU stepdown:
Vitals and urine outputs are done Q2, so at 4pm, 6pm, 8pm & 10pm. Temperatures are only done Q4, so at 4pm & 8pm. We empty all of the foleys at 5pm. For blood sugars, it depends on if the patient is on an AC/HS (before meals/at bedtime) or Q6H schedule. If they are AC/HS, then we get them at 4pm and 9pm and if you're working night shift, again at 0600. If they are on a Q6H schedule, this particular unit gets them at 4 & 10. Everything else is answering call lights, helping the nurses/patients with what they need and doing the other things I mentioned above.
I occasionally float to the ICU, but there I usually work mornings, either 7a-3p or 7a-7p. Techs do not do vitals or UO's in the ICU but sometimes I will go ahead and get them for the nurses if they are busy or if I'm not doing anything.
In the morning I gather all of the glucometers and do the quality control checks because in that unit, they are always done at this time. I then go around to all of the patients who have tube feeds (which is pretty much the whole floor) and prep all of the bags (filling it with the tube feed solution and then letting the solution flow all the way through the tube) and hang them on the side for the nurses. Blood sugars again depend if the patient is on an AC/HS or Q6 schedule. The AC/HS schedule is still the same (11am, 4pm, 9pm, and if you're working night shift, again at 0600) but in the regular ICU, the Q6 schedule is 12 & 6 (not 10 & 4 like in the ICU stepdown). I answer call lights, help the nurses/patients with their needs (oftentimes it takes 2 people to bathe a patient and most of the baths in the ICU are done at night but some nurses prefer to just do in the morning) and again do the things I mentioned above. I round frequently on all of the units I work on but I round even more so in the ICU due to all of the invasive lines and high use of restraints. Plus, nurses will appreciate it when you tell their vented, restrained patient with a bunch of lines that their bottle of propofol is empty and the patient is starting slowly awakening
I know it sounds like a lot, but TRUST ME, you will get everything down as you work. When you float to your units, introduce yourself and make yourself known. Tell them you're new and ask questions - they'll tell you what needs to be done and when and what to expect on the unit. Don't take what I said as a guide to what needs to be done because every unit and different hospitals function differently, but I hope it kind of gives you an idea
Personally I love my job and I love my home floor, but I also love floating to different units because you really gain some experience! I think it makes you more well-rounded because you have exposure to different nursing units, both med-surg and critical care, which are two completely different (but very interesting!) realms of nursing. Good luck to you!
