Im a fairly new lvn with about 6 months expierience working in ltc. Well i worked prn at a ltc facility.so wat happened is a pt had just come in yesterday evening so the am nurse asked me if i could get an order for the pts cpap machine so i called the md on call and got the order.then later on when i checked the pts bs it was at 168 and pt was scheduled 45 units of intermediate insulin and had a sliding scale apart from that which he was supp to get 3 units from his bs reading.pt asked me if he could only take 25 units of the intermediate since he was worried his bs would become low due to him have to take the 45 units and sliding scale.i told him i didnt have the power to give him the 25 units i had to follow mds orders.pt was concerned because he said he started feeling lightheaded at about 100ish bs so i told him id call the md and ask his opinion and see if hed give permisssion for the 25.well to make story short the md on call pretty much reamed me a new one.he said that he was not changing any orders that pt had to take order as is or nothing at all.he was pretty much a jerk.i understand he was upset cause i had called him about the order earlier but i feel he overreacted.did i handle the situation right or wat could i have done differently???
