People will always cry discrimination in every cultural. These days, you have to be sensitive to other cultural, for you don't want to offend or sound bossy. Unless LPNs or RNs say something about the call lights, there isn't too much we can say. It seems to me if the aides hear the call lights, then the nurses desk should hear them too. Where I worked, it was the LPNs who informed the aides that have their residents needed assistant. We were too busy in our rooms attending to the residents to stop everytime a call light went off, which seemed like all the times. We hardly had time to answer call lights due to a.m. care and getting all the residents washed and dressed. Also, as others had mentioned before, it would be nice if LPNs could help aides out, but in the real world, it doesn't always pan out that way.
