Final answer:
Metabolic acidosis is the acid-base imbalance that results from kidney failure. It causes a decrease in blood pH and affects the affinity of hemoglobin for oxygen.
Step-by-step explanation:
Metabolic acidosis is the acid-base imbalance that results from kidney failure. In kidney failure, the kidneys are unable to effectively remove excess hydrogen ions from the blood, leading to an accumulation of acid in the body. This can cause a decrease in blood pH. One consequence of metabolic acidosis is the increased affinity of hemoglobin for oxygen, which impairs the release of oxygen to the tissues.
