Ressurecting this thread.
Joined the forum to ask this same question bc we were also asking this question at work today. Wasn't my patient but a very similar situation where a patient stated they were totally anuric but was getting Lasix in betweek 2 units PRBC's. Must be an oversight by the renal doc...this patient is also on long term dialysis. Anyway glad to see that we were on the right track with our thinking!
