A client with chronic renal failure asks the nurse about the cause of their frequent bone pain. Which explanation by the nurse is accurate?
"The bone pain is related to the body's excess production of calcium, leading to joint inflammation."
"Chronic renal failure causes the body to retain phosphorus, which can weaken your bones and cause pain."
"Frequent bone pain is a common side effect of the medication used to manage chronic renal failure."
"The kidney dysfunction in chronic renal failure leads to low levels of calcium in your bones, resulting in bone pain."
The Correct Answer is B
A. Incorrect. Excess production of calcium in the body is not a typical cause of bone pain in chronic renal failure.
B. Correct. Chronic renal failure can lead to impaired phosphorus excretion, resulting in elevated levels of phosphorus in the blood. High phosphorus levels can lead to bone demineralization, weakening the bones and causing bone pain.
C. Incorrect. While some medications used in the management of chronic renal failure may have side effects, frequent bone pain is not commonly associated with these medications.
D. Incorrect. Kidney dysfunction in chronic renal failure does not typically lead to low levels of calcium in the bones. Instead, it can lead to abnormalities in phosphorus levels, which affect bone health.

D. Correct. There are no special preparations needed for a GFR test. The test can be done at any time, regardless of food intake or hydration status.
Correct Answer is B
Explanation
A. Incorrect. A GFR value of 10 mL/min/1.73m² indicates severe kidney dysfunction, not mild impairment.
B. Correct. A GFR value of 10 mL/min/1.73m² is considered very low and indicates severe kidney dysfunction. At this level, the kidneys are severely damaged and unable to effectively filter waste and fluids from the blood.
C. Incorrect. A GFR value of 10 mL/min/1.73m² is much lower than the threshold for moderate kidney dysfunction.
D. Incorrect. A GFR value of 10 mL/min/1.73m² is far below the normal range and indicates significant kidney dysfunction, not normal kidney function.
