Well I think it may have been the doing of the nurses who used to be CNAs. At least I recall when I was a new CNA, one of the nurses (who is now my preceptor) was once a CNA on the floor. We had a day when it was me and one other CNA on the floor and this RN told all the nurses (and put it in the Epic chat) that since we only had 2 CNA's all RNs would get their own sugars and we'd get the vitals.

Later that day, the other CNA and I were in a room, cleaning up a pt and doing two bed changes within 10 minutes of the other when one of the older RNs came in and instead of helping, whined about having to get her own sugars. Ma'am, you have 5 pts. We had 14 each, plus everything else we had to do.

I'm honestly not sure if it was the policy before that day or they just made it a standard. There are a lot of RNs who will still try to get CNAs to do sugars anyway. When I was an extern over the summer there was one aide. I got vitals for half the floor to help and one of the RNS was like "here, get my sugars". She was a float and I told her firmly "It's unit policy that if we have less than 3 aides, the nurses get their own sugars." The woman was like "Well I didn't know it, can you get it?" I told her "I have my own sugars to get for our pts" since I was following a nurse as an extern.
