Today was an interesting day at work. I had a patient who's on a prescribed eye drop q2h, the order says for R eye. Upon going to give the 1st dose of my shift, she tells me they go in both eyes (what she does at home). She's 89 and AAO x 3. So this is what I did.. the daughter comes in while I'm giving one of the doses and says, "you just made a medication error". Stating she's only supposed to get it in the R eye despite what the patient says. I understand that, yes I did commit med errors by doing this. My question is: if reported will, what's the worse that can happen? I'm a worrier, so any help would be great. Thanks!
