I'm a new LPN (Jan. 2012) and I work LTC. I take care of a patient and his main dx is dementia. He had routine labs drawn and had a BGL over 800 (was never diagnosed with diabetes & is over 75 y/0). He was treated @ the hospital & returned to our LTC facility a week later. He now gets Lantus daily (24 units) & his blood sugars continue to spike up in the 500's with no s/sx of other infection: v/s stable, afebrile, UA negative for infection, LCTA, losing weight (probably d/t elevated BGL). Any thoughts/advice?
