I guess im a little confused, the boss of the ER said you could be a tech until July, even though you are an RN. Are they willing to pay you an RN salary. Trust me you do not want to get yourself into that situation, they will expect you to do RN jobs to help out but your duty is a tech. If something goes wrong with a pt. while doing a job outside the scope of a tech you could get in serious trouble with the hospital and let me tell you your manager and other nurses will not back you up. Why dont you work on the med surge floor until july and then transfer to the ER. Good Luck
