Which type of water balance disorder would be caused by renal failure?

a. Dehydration

b. Water intoxication

c. Volume excess

d. Hypovolemia

Answer: C. Volume Excess

Explanation:

Patients with impaired kidney function or renal failure, usually suffer from an excess volume of water in their bodies, because the urinary output they have is decreased and in some cases absent. Water excess starts accumulating on the circulatory system, and then it diffuses into the soft tissues of the body.

They also suffer from electrolytic disorders.
