In a semi emergency situation and a surgeon asks you to give 5000u IVP and then hang 1000u/hr of Heparin, but did not order to to get a PTT, do you normally get one anyone? He did not order a heparin protocol? I am new to med surg and I hear several seasoned nurses saying different things. I am not sure. I think next time I will ask the dr. if he wants a PTT. However, it seemed to be an emergency situation.
