Heading to sub-acute unit at an LTC...what should I expect?

First time going into a sub-acute floor at an LTC...what should I expect? Have zero experience suctioning pts, giving trach care, etc. Just never was assigned to these patients during acute care setting clinicals. Have no idea how to prepare other than review step-by-step procedures in my textbooks...didn't get much practice in our labs either...only did it once and that was quite a while back. Memory is fuzzy on the steps. I'm a little apprehensive, but maybe that's normal. Will I be taken aback by the patients' conditions? I dunno.... I hope I do a noble service to my patients...or are they called residents?

Any advice is appreciated. God bless you all!
