A nurse is caring for a client who has an admited diagnosis of renal calculi and a medical history of hypertension and gout. The client works 6 days a week outside in temperatures between 32.2°C to 37.8°C (90°F to 100°F). Which of the following should the nurse tell the client to prevent a recurrence of renal calculi?

Choice A rationale: Cantaloupe is high in potassium. Clients with acute kidney injury (AKI) have impaired potassium excretion, and consuming high-potassium foods increases the risk of hyperkalemia, which can lead to cardiac arrhythmias.

Choice B rationale: Baked potatoes contain significant potassium, especially in the skin. In AKI, potassium retention is dangerous, so this choice reflects poor understanding of dietary restrictions for renal safety.

Choice C rationale: Yogurt is rich in potassium and phosphorus. In AKI, both electrolytes may accumulate due to reduced renal clearance, making yogurt an inappropriate choice without close monitoring.

Choice D rationale: Pecans are low in potassium, making them a safer snack for clients with AKI. Choosing low-potassium foods demonstrates appropriate understanding of renal dietary management.

Choice A reason: Hyperkalemia refers to high potassium levels, which may not directly cause shortness of breath and swelling.

Choice B reason: Hypervolemia, or fluid overload, is likely the cause of the client's symptoms, including shortness of breath, swelling, crackles in the lungs, and elevated blood pressure.

Choice C reason: Hypovolemia, or fluid deficit, would not typically present with swelling and crackles in the lungs.

Choice D reason: Hyponatremia refers to low sodium levels, which may not directly cause the symptoms described.
