Final answer:
The most suitable lunch menu for Mr. Kassam with chronic renal failure is option c) Turkey, 60 g, on white bread with mayonnaise, an apple, and 250 mL of ginger ale, as it is low in protein and sodium, which is important to consider in a renal diet.
Step-by-step explanation:
An appropriate lunch menu for a patient with chronic renal failure, focusing on diet therapy, would need to take into account the need for a low-protein, low-sodium, and possibly low-potassium diet depending on the patient's specific bloodwork results. Out of the options provided, the most suitable lunch menu for Mr. Kassam would be:
c) Turkey, 60 g, on white bread with mayonnaise, an apple, and 250 mL of ginger ale.
This option is relatively low in protein and sodium compared to the other choices and does not include high potassium foods like bananas or milk. It's important for patients with renal failure to avoid high sodium and potassium foods that can further strain the kidneys. Maintaining an adequate intake of calcium, avoiding oxalate-rich foods, and drinking enough water to make 2 to 2.5 liters of urine per day are also part of the preventive dietary strategy for chronic kidney disease (CKD).
