Always remember you can only be in one place at one time. You will CONTINUALLY have 2 or 3 people who all want to do something at the same time and need help, at least if you work days or evenings. During meals we would always have some people who wanted to go to the BR or back to bed NOW, while other residents still needed to be fed. Or residents that insisted on sleeping in, then all wanted to get up NOW. Residents are generally in their own little world, and most wont understand that you have other people to help as well. THEY want help NOW and cant understand why you're making them wait.(in fairness you have to understand how horrible it is to not be able to go the BR or do what you want when you want).
Don't let it get to you, you cannot please all of the people all of the time in LTC, just do what you can and learn to prioritize requests and know what can wait and who and what needs to be addressed first, and try to get as many things done at once as you can. For instance if someone wants to go the BR in the morning, try to get them to bath and get dressed while they are up, instead of wasting all this time toileting them and then getting them back to bed, only to have them ring 45 minutes later wanting to get back up. This is especially important if someone is a 2 person lift.
Also, NEVER lose your temper with a resident. That is the fastest way to get fired or worse. You will almost certainly have residents say some really nasty stuff to you at some point, you gotta let it roll off you like water on a duck. CNAs can usually deal with a resident trying to hit them or bite them or whatever, but I've seen some get rattled by some of the things residents will say, especially if its from one of the more lucid acting ones.
Also remember to have a life outside of work totally unrelated to your job, so you can de stress and get your mind off the job. If your job is your life 24/7 you will go nuts.
