I am not really an experienced nurse (I graduated in Dec '08), but i have been working 3-11 in LTC since April. Here's how a typical shifts goes:
Get on the floor, get report, count narcs, check if there are any orders or lab results that need to be followed up on before the clinic closes for the day, look though the MAR and use paper clips to mark my meds (a clip in the left side means there is a 1600 med on that page, middle for 1800 and right side for 2000)
Then I start my 1600 med pass and also get my BG checks and insulins for the diabetics. After I get my med pass and insulins done, I help the CNAs bring residents to the dining room and make sure they have enough people to help feed. (Of course some days I'm chasing after the diabetics that are headed to the dining room when I haven't gotten the BG yet!) Once everyone is settled in the dining room, I take my dinner break.
When I come back from break, I get out the tx book and see what kind of tx I have to do. Some of the less time consuming things (e.g. diabetic foot checks, creams/lotions) I do with my 2000 med pass.
Then I start my 1800 med pass. The 1800 med pass is pretty light, so sometimes I will sit down for 10-15 min and work on my charting after the 1800 med pass, but most nights there are too many distractions and it's almost 1900 when I finish, so I start on the 2000 med pass right away. I've learned which residents get crabby when you wake them up to give them their meds as well as which ones have a much easier time swallowing pills sitting up in their W/C vs. laying in bed, so I try to get to those people first.
On a good day, it's 2130 or so when I finish my 2000 med pass so then I go take a 15 min break. After that I finish up with my txs, check over the MAR to be sure I didn't miss anything, tape report for the next shift and do my charting.
Of course, things rarely go this smoothly. There's usually a fall, a new admit, a residents having major behaviors, calls from family wanting to know how their mother is doing, etc. putting a wrench in my plans. I've learned to just go with the flow and do my best to get my work done.
As far as my sleep schedule, I've always liked staying up late and sleeping in, so it's been great for me. I have a 5 month old dtr, so that can make getting enough sleep difficult if she wants to get up early. But usually I get home around midnite. Sometimes my dtr will wake up and want to nurse when I get home, but if she is sleeping soundly I just let her sleep. I am always starving when I get home, so I usully have a snack and watch some TV or read to wind down. I get to bed sometime between 0100 and 0200. Most morning my dtr wakes up sometime between 0600 and 0700. Since I'm nursing, there's no delegating the AM feeding to my husband, so I have to get up with her. But she goes down for a morning nap aroud 0900 until 1100 or so, so I usually take a morning nap with her. So I kind of feel like a bum since I don't get up and get going until 1000 or 1100 most days. On my days off I keep the same schedule for the most part, although I might take an afternoon nap with my dtr instead of the morning nap.
Good luck with everything. Even though I am so busy and sometimes it just seems impossible to get everything done, I do love my residents and enjoy my job. After a few weeks, you'll develop your own routine that works for you.
