Nurses getting all vitals and blood sugars on Med/Surg unit

I work on a med/surg unit with primarily neuro patients. Our manager has decided nurses will now be responsible for all vital signs and blood sugars. This is not an organization-wide move just my unit. We will still have techs, they will just have less responsibilities.

I typically have 5-6 patients and am already fighting for my life with the current workload. Does anyone else have a Med/Surg unit that does this? Or is this complete bullshit?? New nurse here! Please help!
