Hello,

high bun and creatinine usually indicates renal failure. Since she's had increased values in the past, it's probably chronic renal failure (CRF). CRF may cause increased potassium levels. The severity depends on how high they are. If her potassium is higher than 6mEq/L then you should immediately contact your doctor for investigation.

If the ratio of bun to creatinine is high (>20) then she can try drinking some water (if she hasn't done so already) because a high ratio indicates dehydration which is a reversible cause of renal failure.

I hope I've helped!
Contact me again, if you'd like more information.

Kind Regards!
