A nurse is caring for a client experiencing kidney failure. The nurse recognizes that kidney failure causes the loss of which of the following processes integral to maintaining homeostasis?
Distribution of protein
Filtration of the blood
Metabolism of medications
Ability to hold urine
The Correct Answer is B
A. Distribution of protein: While protein distribution may be affected in kidney disease, it is not a primary function of the kidneys.
B. Filtration of the blood: The kidneys are responsible for filtering waste products and excess substances from the blood. In kidney failure, this filtration process is impaired, leading to the accumulation of toxins in the body.
C. Metabolism of medications: Although the kidneys do play a role in drug excretion, drug metabolism primarily occurs in the liver. Kidney failure may affect the excretion phase.
D. Ability to hold urine: While kidney failure can affect urinary function, the ability to hold urine is primarily a bladder function, not directly a function of the kidneys.
