What is the Most Likely Effect of a Deficiency of Aldosterone

Question

What is the most likely effect of a deficiency of aldosterone?
A) High blood pressure
B) Low level of potassium in the blood
C) Low blood volume and hypotension
D) Goiter formation

Accepted Answer

Aldosterone is responsible for promoting sodium and water reabsorption in the kidneys, which increases blood volume and blood pressure. A deficiency in aldosterone would result in decreased reabsorption of sodium and water, leading to low blood volume and hypotension. This can also lead to an increase in potassium levels in the blood (hyperkalemia) as aldosterone also helps regulate potassium levels in the body. Goiter formation is not related to aldosterone deficiency.
