A nurse is reinforcing nutrition teaching for a client who has chronic kidney disease about limiting foods high in potassium. Which of the following foods should the nurse instruct the client to avoid? (Select all that apply.)
Orange juice.
White rice.
Corn flakes cereal.
Watermelon.
Bananas.
Correct Answer : A,E
The correct answer is Choice A, Choice E
Choice A rationale: Orange juice contains approximately 496 mg of potassium per 8 oz serving, making it a high-potassium beverage. In chronic kidney disease, impaired renal excretion of potassium leads to accumulation and risk of hyperkalemia. Normal serum potassium levels range from 3.5 to 5.0 mEq/L. Elevated levels can cause cardiac arrhythmias, muscle weakness, and paralysis. Avoiding potassium-rich fluids like orange juice is essential to prevent life-threatening complications in clients with reduced glomerular filtration rates.
Choice B rationale: White rice contains approximately 26 mg of potassium per 1 cup cooked, classifying it as a low-potassium food. It is safe for clients with chronic kidney disease and often recommended due to its minimal contribution to serum potassium levels. Unlike whole grains, white rice has reduced mineral content, including potassium and phosphorus. Maintaining serum potassium within the normal range of 3.5 to 5.0 mEq/L is critical, and white rice does not pose a risk of hyperkalemia.
Choice C rationale: Corn flakes cereal contains approximately 30 to 40 mg of potassium per 1 cup serving, making it a low-potassium option suitable for renal diets. It lacks the bran and whole grain components that elevate potassium content in other cereals. In chronic kidney disease, dietary potassium restriction is necessary to prevent hyperkalemia. Corn flakes do not significantly affect serum potassium levels, which should remain between 3.5 and 5.0 mEq/L to avoid neuromuscular and cardiac disturbances.
Choice D rationale: Watermelon contains approximately 112 mg of potassium per 100 grams, which is considered low to moderate. While excessive intake could contribute to potassium load, typical servings do not pose a significant risk. In chronic kidney disease, potassium restriction targets foods exceeding 200 mg per serving. Watermelon’s potassium content is below this threshold, making it generally safe when consumed in moderation. Serum potassium should be maintained within 3.5 to 5.0 mEq/L to prevent hyperkalemia.
Choice E rationale: Bananas contain approximately 422 mg of potassium per medium fruit, placing them among the highest potassium-containing fruits. In chronic kidney disease, potassium excretion is impaired, and consuming bananas can rapidly elevate serum potassium levels. Hyperkalemia increases the risk of ventricular arrhythmias and cardiac arrest. Dietary potassium restriction is essential to maintain levels within the safe range of 3.5 to 5.0 mEq/L. Therefore, bananas should be avoided to prevent life-threatening electrolyte disturbances.

Correct Answer is D
Explanation
Choice A rationale
Maintaining a low carbohydrate diet is not specifically recommended for clients with chronic kidney disease (CKD). Instead, the focus is on managing protein, sodium, potassium, and phosphorus intake to prevent further kidney damage and manage symptoms.
Choice B rationale
Eliminating ingestion of foods high in protein is incorrect. While protein intake should be moderated, it should not be completely eliminated. Clients with CKD are advised to consume a controlled amount of high-quality protein to reduce the burden on the kidneys while ensuring adequate nutrition.
Choice C rationale
Increasing intake of sodium-containing food is incorrect. Clients with CKD should restrict sodium intake to help control blood pressure and prevent fluid retention, which can exacerbate kidney damage.
Choice D rationale
Reducing intake of foods high in potassium is correct. Clients with CKD often have difficulty excreting potassium, leading to hyperkalemia, which can be dangerous. Therefore, it is important to limit foods high in potassium.
Correct Answer is ["B","D","E"]
Explanation
Choice A rationale
Contacting the surgeon if the client reports a continual need to void is not necessary unless it is accompanied by other symptoms such as pain or discomfort. The sensation of needing to void can be common after a TURP due to the presence of the catheter and bladder irrigation. This sensation usually resolves as the bladder heals and adjusts to the catheter.
Choice B rationale
Using sterile technique when preparing the irrigation solution is crucial to prevent infection. Sterile technique ensures that no pathogens are introduced into the bladder, which could lead to complications such as urinary tract infections or sepsis. Maintaining a sterile environment is a fundamental aspect of postoperative care, especially when dealing with invasive procedures like TURP1.
Choice C rationale
Adding the amount of bladder irrigation to the total output is incorrect. The correct practice is to subtract the amount of irrigation solution used from the total output to determine the actual urine output. This helps in accurately monitoring the client’s fluid balance and kidney function. Incorrectly adding the irrigation amount could lead to misinterpretation of the client’s urinary output and fluid status.
Choice D rationale
Notifying the surgeon if the urine is bright red or has large clots is essential. Bright red urine or large clots can indicate active bleeding, which is a potential complication after TURP. Early detection and intervention are crucial to prevent significant blood loss and other complications. The nurse should monitor the urine color and consistency closely and report any abnormalities immediately.
Choice E rationale
Ensuring the drainage tubing is patent and without obstruction is vital for the effectiveness of continuous bladder irrigation. Obstructions in the tubing can lead to bladder distention, discomfort, and potential damage to the bladder and urethra. Regularly checking the tubing for kinks or blockages and ensuring a free flow of irrigation solution helps maintain proper bladder function and prevent complications.
