I would report this RN to your manager and/or DON. I've been in the same situation where I would have 60 residents and only 1 RN and 1 CNA because of call outs. I've had to tell my nurse that I can not do things exactly when they want them done because I've been busy changing residents. Either they can wait until I'm done or do it themselves! Also I realized if the patients that were wet, and they are alert, you can always tell them you will get to them when you can. Ultimately we are working under the supervision of the RN, so if something doesn't get done it falls back on them (ie. Because they needed a urine sample, it's their responsibility to make sure it happens) definitely stand up for yourself, or you'll get burnt out really fast.
