Management of renal failure involves restriction of water, salt, and protein intake. This approach helps to lessen the strain on the urinary system by
A) maximizing the volume of urine produced.
B) preventing any increase in blood plasma pH.
C) preventing the generation of large quantities of nitrogenous waste products.
D) regulating daily caloric intake.
E) preventing the excretion of any organic waste products.

Question

Quizplus · Accepted Answer

Restriction of water, salt, and protein intake helps to prevent the generation of large quantities of nitrogenous waste products, which can be harmful to the body in renal failure. This is because the kidneys are not able to efficiently filter out these waste products from the blood in renal failure, so reducing their production helps to lessen the strain on the urinary system. Maximizing the volume of urine produced (choice A) and regulating daily caloric intake (choice D) are not specific strategies for managing renal failure, while preventing any increase in blood plasma pH (choice B) and preventing the excretion of any organic waste products (choice E) are not appropriate goals in renal failure management.
