1. if a person is in renal failure, would blood test likely show hypokalemia or hyperkalemia?

2. would erythrocyte casts in the urine indicate glomerular or tubule disease?

Solutions

Expert Solution

1 - Blood test would show hyperkalemia due to reduced renal secretion and leakage of potassium from intracellular space. This results in hyperkalemia in renal failure .

2 - Erythrocyte cast may be found either due to RBC leakage from glomerular membrane or may be due to bleeding in tubular nephron. This indicates glomerulonephritis or vasculitis . RBC cast most commonly associated to glomerular disease .
