In a busy office , it is eassy for mistakes to happen. I am the only nurse in my office, and do not have another nurse to do 2nd checks with. I ask the pt their name (even though i know them) and i show them their name on the bag and ask them if that is their name, and i tell them which medication i am giving. A coworker of mine at another office had a similar incident where she drew up the pts aranesp, got called to the phone, and gave the injection to another nurse to give. she told her what it was and for which pt, and that nurse gave it to the pt push via port. She stated, "she thought it was his velcade."
