I worked with a new nurse for four hours - first time I had worked with her, who had not charted that the blood sugars were done before dinner. I asked her if she had done them, and if not I would be happy to help her get them. She said that she got them. She then charted five blood sugars without having any kind of note to look at. Nothing written on a paper towel, tongue depressor, alcohol wipe packet, her hand, nothing. I could see the wheels turning as she made the numbers up. I then got the glucometer and checked the numbers. Not only had she not checked blood sugars at that time, she hadn't prior to lunch, she hadn't prior to dinner the day before, nor prior to lunch the day before. The numbers on the glucometer matched the blood sugars that the nurse working the opposite shift had documented for two days, he worked nights so had the bedtime and early AM blood sugars to do. However, those were the only blood sugars recorded on the glucometer. I notified my supervisor and was told to write a report (which I did). When the supervisors talked to the nurse, she said that she couldn't get our glucometer to work and borrowed one from next unit. Funny thing? Their glucometer was really not working so they borrowed ours in the rare instances that they needed to do blood sugars (they only had one weekly blood sugar to check)! This new nurse was turned into the Board of Nursing and rec'd disciplinary action. Wouldn't it have been much easier to just take the blood sugars?
