What happens to the BUN level when a patient is hypervolemia? | BUN decreased (diluted) |
What happens to the HCT level when a patient is hypervolemia? | HCT decreased (diluted) |
When a patient is hypervolemic, is the urine NA+ level increased or decreased? | Generally increased, but this depends on the cause of the hypervolemia. |
