Well...thank goodness someone replied. I was beginning to feel.....how do you put it?.....DUMB! Yes, we had same protocol for Ptt. Generally, our Hep was pulled fromt the PIXIS and was automatically documented in the computer. Then you would go back and rechart on it. I've never had to co-sign or have someone double check the Hep that I was getting ready to administer. I read in other threads that this was done and it stumped me. I was just curious. I've only been a nurse fot 3 years and only practiced 2 out of those three. I've only worked at 1 hospital. Thanks for taking the time to answer my question.
