Mrs. f's blood work has come back and shows that she has low plasma osmolarity and decreased levels of plasma proteins and plasma k+. you can see how plasma proteins are related to her liver failure, since the liver synthesizes plasma proteins. but why does she have low k + levels?

Mrs. F has low k + levels because the liver destroys aldosterone. Aldosterone is a substance used to stimulate the secretion of potassium (k+) in the kidneys. Destruction of this enzyme would mean the reduction of potassium in the body. The inhibition of aldosterone occurs when renin is inhibited.
