A client with chronic renal failure reports persistent pruritus (itching). What is the nurse's best response?

"Pruritus is unrelated to chronic renal failure; it may be due to a skin condition."

"Itching is a common symptom of chronic renal failure, caused by the buildup of waste products in the blood."

"Pruritus is a side effect of the medications used to treat chronic renal failure."

"Persistent itching is a sign of an allergic reaction; let's check if you started any new medications."

Answer and Explanation

The Correct Answer is B

A. Incorrect. Pruritus (itching) is a common symptom of chronic renal failure and is related to the buildup of waste products and toxins in the blood, leading to skin irritation.

B. Correct. Pruritus is a common and distressing symptom of chronic renal failure, caused by the retention of uremic toxins in the blood. These toxins can irritate the skin and lead to itching.

C. Incorrect. While medications can sometimes cause pruritus as a side effect, it is not the primary cause of itching in clients with chronic renal failure.

D. Incorrect. Persistent pruritus in a client with chronic renal failure is not necessarily indicative of an allergic reaction to medications. It is more likely related to the buildup of waste products in the blood.

Correct Answer is B

Explanation

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.

A. "Cardiovascular disease doesn't affect the kidneys; it only affects the heart." B. "High cholesterol levels have no connection to chronic renal failure." C. "Heart disease can cause kidney damage due to decreased blood flow to the kidneys." D. "There is no relationship between high blood pressure and kidney function."

Correct Answer is C

Explanation

A. Incorrect. Cardiovascular disease can impact kidney health. The heart and kidneys are closely connected, and conditions that affect the heart can also have implications for kidney function.

B. Incorrect. High cholesterol levels can contribute to cardiovascular disease, and cardiovascular disease is a significant risk factor for chronic renal failure. Therefore, high cholesterol indirectly impacts kidney health.

C. Correct. Cardiovascular disease, including conditions like heart failure or atherosclerosis, can lead to decreased blood flow to the kidneys, impairing kidney function and contributing to chronic renal failure.

D. Incorrect. High blood pressure is a well-established risk factor for chronic renal failure. Uncontrolled hypertension can damage the blood vessels in the kidneys, leading to kidney dysfunction over time.
