d. increased muscle mass.
B
In patients with acute renal failure, sudden increases in weight are usually caused by fluid reten-tion. Most patients have very little appetite so they are unlikely to gain fat and they are inactive so they are unlikely to increase muscle mass. Also, gains in muscle mass and fat stores tend to be slow. Urea retention does not cause an increase in weight.
