I have been a nurse for almost one year- I just had a major med error this morning- I gave the wrong insulin to a patient...I gave him 32 units instead of 18- my heart sunk and I have had that nautious feeling all day. I reported it to the Dr right away and also filled out a med error report sheet. The residents blood sugar was over 200 this morning, then I had to go home and sleep- I worked the night shift. HAs anyone done this before?? Will I lose my job? Thank goodness the patient is ok.....
