A client with chronic renal failure asks the nurse why they need to limit their dietary protein intake. What is the nurse's best response?

"Reducing protein intake can help prevent calcium loss and bone fractures."

"Limiting protein intake can reduce the workload on your kidneys and slow disease progression."

"Decreasing protein intake will help improve your appetite and overall nutritional status."

"By reducing protein intake, your body will have fewer waste products to excrete, reducing strain on your kidneys."

Answer and Explanation

The Correct Answer is B

A. Incorrect. Reducing protein intake can lead to calcium loss and bone fractures in clients with chronic renal failure, as it may affect

bone health.

B. Correct. Limiting protein intake is a common dietary recommendation for clients with chronic renal failure to reduce the workload on the kidneys and slow the progression of kidney damage. Protein metabolism produces waste products that the kidneys must filter and excrete, and reducing protein intake can help alleviate this burden on the already compromised kidneys.

C. Incorrect. Decreasing protein intake may not necessarily improve appetite or overall nutritional status, as protein is essential for maintaining body functions and tissue repair.

D. Incorrect. While reducing protein intake can result in fewer waste products being generated, the primary reason for limiting protein intake in chronic renal failure is to reduce the strain on the kidneys, not solely to decrease waste production.

Correct Answer is D

Explanation

A. Incorrect. Smoking and tobacco use are harmful to the kidneys and can increase the risk of chronic renal failure.

B. Incorrect. While genetic factors may play a role in some cases of chronic renal failure, lifestyle changes can significantly impact the risk and progression of kidney disease.

C. Incorrect. While a history of kidney stones may be associated with an increased risk of kidney damage, it is not a primary risk factor for chronic renal failure.

D. Correct. Conditions such as hypertension and diabetes are two of the leading causes of chronic renal failure. Uncontrolled high blood pressure and elevated blood sugar levels can damage the blood vessels and filtering units of the kidneys, leading to chronic kidney disease over time.

A. Convert the creatinine level to micromoles per liter (μmol/L). B. Obtain a 24-hour urine sample for creatinine clearance measurement. C. Calculate the client's body surface area to adjust the GFR calculation. D. Plug the creatinine level into the appropriate GFR formula.

Correct Answer is D

Explanation

A. Incorrect. Converting the creatinine level to micromoles per liter is not necessary for the GFR calculation.

B. Incorrect. While a 24-hour urine sample can be used to measure creatinine clearance, it is not required for the GFR calculation, which can be estimated using formulas.

C. Incorrect. Calculating the body surface area is not necessary for the GFR calculation.

D. Correct. The GFR can be estimated using formulas that include the serum creatinine level, such as the Modification of Diet in Renal Disease (MDRD. formula or the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation.
