Before you get on to the ward, ensure you have written down notes on anything that maybe needed for that day, during handover write down anything thats required. Build confidence in your self by sticking to your time protocol, get to know the ward like its the palm of your hand.
Perfect note: As the above poster has stated in response to your question OP, ensure you have everything you that is required before you walk the room.
My advice is make a list, a pocket diary treat it as your companion. Write down everything you need to do, and tick the things off you have done.
