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? which of the liver functions below is most likely to affect mrs. f’s k+levels? a. the liver creates lipoproteins. b. the liver destroys aldosterone. c. the liver converts ammonia to urea. d. the liver stores and releases glucose. e. the liver makes bile, which is needed to absorb lipid-soluble vitamins.

The correct answer is option B.

Explanation:

In the given case, Mrs. F is suffering from liver disease, which is witnessed by her plasma protein examination. The secretion of plasma proteins is done from liver, and its reduction is associated with liver dysfunction. Apart from this, liver performs various other activities.  

The Renin Angiotensin Aldosterone System is reliant upon the liver. In the process, angiotensinogen I get transformed into angiotensinogen II in liver. However, due to the defect in liver, the secretion of potassium is not monitored by kidney, and it gets secreted in urine. Thus, the concentration of potassium in urine becomes high, while the blood potassium level reduces.  

In the given case, Mrs. F has low potassium levels as the liver is destroying aldosterone. Aldosterone refers to an enzyme that is used to instigate the secretion of potassium in the kidneys. Destruction of this enzyme signifies the reduction of potassium in the body. The inhibition of aldosterone takes place when the inhibition of renin takes place.
