Which term best describes a treatment to replace kidney function when the kidneys fail?
Correct Answer:
Dialysis
Explanation:
Dialysis is a treatment that substitutes kidney function when the kidneys fail. It works by filtering waste products from the blood, balancing electrolytes, and removing excess fluid. This can be done with hemodialysis, which uses a machine and a dialyzer, or with peritoneal dialysis, which uses the peritoneal membrane as the filter. The other terms refer to types of gastrointestinal bleeding (melena, hematochezia, hematemesis) and do not describe kidney replacement therapy. So dialysis best describes the treatment for replacing kidney function.
