10 Med Errors in 4hrs? I can understand one or two but wow...You said you had computer problems did you contact the supervisor once you realize the computer was not functioning well? If you did let the supervisor know, you can include that in your email. Are you represented by the Union? Thankfully, there was no harm to the patient and no narcotics were involved. That said though, I still think they should have given you a verbal warning followed by a written one before reporting you to the Nursing board.
