Is this a thing?

I only have MS and OR exp... is this a thing in emergency medicine? Was holding boarders on the ER the other day. Assumed care for a pt at 0700. Their glucose at 1900 the night before was 398. I had gotten no report before assuming care, didn't even see/meet the offgoing RN. No recheck of BG or insulin overnight. So I check her BG and the glucometer reads HI (>600). So I notified the MD and ordered a stat CMET. Called lab 4 times that morning, and notified the charge, but no one ever came to draw the labs I needed until around noon when the patient got a bed and I told the charge I could not take the patient to their room until this was addressed. The charge later told me "normally we just repeat the max dose of insulin until we get a reading on the glucometer." For my own educational purposes, is that a thing?
