the nurse completes dietary teaching with a client who has chronic kidney failure. the nurse determines more teaching is needed
VashaNatasha [74]

Answer:

The options

"I will eat more oranges and other foods with vitamin C."

"I should increase dairy products in my diet."

"I should add protein powder to my fruit smoothies."

The CORRECT ANSWER IS

"I will eat more oranges and other foods with vitamin C."

Explanation:

"I will eat more oranges and other foods with vitamin C."

Citrus fruits are rich in potassium and should be stayed away from, since kidneys find it difficult to remove the excess potassium. Examples of foods that are rich in potassium are dried fruits, avocado, tomato, potatoes, and bananas. This statement indicates that additional teaching is needed.

In kidney failure, the client stands a higer chance for hyperkalemia, hypernatremia, and hyperphosphatemia.

Potassium, is found in large amounts in citrus fruits and dried fruits, and there's need to take these fruits with caution.

Phosphorus is limited due to the important balance of potassium electrolyte with calcium. Protein is inhibited as the failure to remove uric acid, which is produced during protein metabolism, via the kidneys. Sodium, obtained in foods, is also restrained to avoid fluid overload and edema.
