When I was in the hospital for 10 days with gangrene, I was getting 3 different antibiotics IV on a rotating basis - a bag of one type would empty and the next bag of the second kind would replace it, followed by the 3rd, then back to the first and so on. This went on the entire time I was there, 24/7.
So one night a night nurse I hadn't seen before came in to change the Gentamicin (and I'm sure I butchered that spelling!) for Levaquin. I held up my arm for her just like every one of the other nurses had always asked me to do. She smiled as she unhooked the first antibiotic and said, "Oh, deary, I don't need that arm. I'm just going to replace this one and it'll go straight into your IV on this side."
That really made me angry! I was crabby enough by then anyway - I'd already hung my doctor in effigy on my hospital room door the day before. (That's another long story!)
I snapped back, "No, you're not putting that into my IV....not until you've looked at the hospital ID band on my arm and compared it to the bag in your hand and your orders." She was the first (and the only) nurse who'd come in and tried to do something without double checking that minor little detail of making sure the right person was getting the right medication. It never happened again,either!
You know, most us of try to be good patients, but there just comes a time when we have to say, "Look, I have a problem with what you're doing and I want to see someone else."
