Went for kidney scan yesterday. They put a IV in me and handed me contrast to drink. I drank it dutifully. When I walked into the cat scan room the tech was like "OH OH". I was supposed to have injected dye. So they gave me two options. Stay there and drink water in attempt to flush it out of my system. Or reschedule at later date. I rescheduled. I have seen to many situations as a med/surg nurse where that contrast just would not flush. I did not want to spend 3 or 4 hours only to find that they could not get scan anyway. I am glad I did not say I am a nurse. I would have looked dumb for not knowing mistake being made.
