Hi, I did it for 7 years in a really small setting with max 6 people with learning disabilities.
A night shift would be 9pm start to 7am.
I would arrive, get a handover from the day staff, go round and check everyone, if they weren't in bed yet then they would need to be hoisted into bed, toileted, made comfy, pads changed.
We would then have general housekeeping duties such as hoovering, mopping, washing clothes, ironing, emptying bins. The rest of the night was just checking in on the residents as required, we used to sit and watch TV in the lounge or read. 2am to 4am is the worst time.
Then around 5.30 am we used to change pads again, administer any medication and write up the daily records noting what had happened overnight.
Obviously it wasn't always that simple, over my time there I learnt how to change stomas, administer epilepsy medication, set up overnight gastric feeding tubes. We also had 2 overnight deaths which were difficult.
Overall it was a very rewarding job and I miss it sometimes, it was ideal when my kids were young as we didn't need childcare.
Good luck!
