You are caring for a patient after his surgery and you also have 6 other patients one of whom is actively hemorrhaging. You ask for a colleage's to help by helping you hang a IV for one of your patients so you can deal with the one that is hemorrhaging. But she responds, "sorry I am busy too; you will have to deal with it yourself!". You note that she has been talking with her husband on the phone for the last 20 minutes.
How can you respond in an assertive manner?
