A nurse is obtaining a nutritional history from a client who has a new diagnosis of chronic kidney disease. Which of the following client statements indicates additional teaching is needed?

A. "I don't add salt to my food anymore.": Limiting sodium intake is appropriate for clients with chronic kidney disease (CKD) to help manage fluid retention and blood pressure. This statement reflects proper understanding and does not require additional teaching. B. "I read nutrition labels before I buy something.": Reading nutrition labels helps clients monitor sodium, potassium, phosphorus, and protein intake, which is essential in CKD management. This demonstrates effective self-management and does not require further teaching. C. "I'm eating larger portions of meat.": Consuming large portions of meat increases protein and phosphorus intake, which can worsen kidney function and complicate CKD management. This statement indicates a misunderstanding of dietary restrictions, and additional teaching is needed about appropriate protein portion sizes. D. "I've started using olive oil instead of butter.": Replacing butter with olive oil is appropriate, as it provides healthier fats that do not contribute to hyperphosphatemia or cardiovascular risk. This reflects correct dietary adaptation and does not require further teaching.
