today i had a pt who is on dyalisis. the wife was at the bedside when the pt who is on a 1800 cc fluid retriction asked for a soda. i notified the pt t hat i would substitue the amout from his fluid allowance and thatvit would be a diet soda. he agreed. but then wife said to me that it must be clear. that a nephrologist had told her that he should not drink anything dark. be it soda coffee tea, etc. now i just got home and am looking online for a rational of why. i have no such luck, so my question is has anybody heard of this and what is the rational?
i'd greatly appreciate a answer.
