Quizplus · Accepted Answer

The increase in serum urea nitrogen and creatinine in a client with acute renal failure is due to the inability of the kidneys to filter these waste products from the blood. This leads to an accumulation of these substances in the blood, which can be further exacerbated by the breakdown of muscle mass in the body. This breakdown can occur due to a number of factors, including malnutrition or immobility, leading to an increase in serum urea nitrogen and creatinine. Inadequate fluid intake, elevated blood pressure, and increased fluid retention may all be contributing factors to acute renal failure, but they do not directly cause an increase in serum urea nitrogen and creatinine.
