3-11 in LTC

At the long term care unit I work on we just went to 8 hour shifts. Since going to 8 hour shifts we are short 1 nurse for 3-11. We do have a med cma that does pass meds for 25 of the residents. however i still have to do the other 25 residents med pass plus charge nurse responsibilies for the whole 57 bed unit. We are down 7 beds at present. I just think it is too much. If a resdint falls or gets a skin tear or md makes rounds or some one goes bad, your in a mess. Does any one else think this is too much or am I just being to sensitve to change. This is how my DON put it when I voiced my opinion.
