A nurse is caring for a client who has end-stage renal disease and must limit protein intake; therefore, the protein the nurse recommends should be complete proteins. Which of the following foods should the nurse plan to include in the client’s diet?

Choice A reason: High protein diets (>2.0 grams/kg daily) increase nitrogen from amino acid metabolism, forming urea that kidneys must excrete. Excessive nitrogen load can strain kidneys, potentially causing damage in susceptible individuals (e.g., those with renal disease), as filtration demands exceed normal capacity, leading to renal stress.

Choice B reason: Sodium is primarily linked to fluid balance and blood pressure, not protein metabolism. While high sodium intake can strain kidneys, it is not the primary substance excreted in high protein diets, which produce nitrogen waste, making sodium an incorrect choice for this context.

Choice C reason: Water is essential for kidney function, aiding waste excretion, but it is not a substance produced by protein metabolism. High protein diets increase water needs indirectly, but the kidneys excrete nitrogen-based urea, not water, making this an incorrect choice for the question.

Choice D reason: Potassium is involved in electrolyte balance, not directly linked to protein metabolism. High protein diets do not significantly increase potassium excretion compared to nitrogen, which forms urea, the primary waste product taxing kidneys, making potassium an incorrect choice for this question.

Choice A reason: Brussels sprouts cooked in butter provide minimal protein (about 3 grams per cup) and are primarily a vegetable source of fiber and vitamins. Butter adds fat but no protein, making this inadequate for post-surgery healing, which requires high-quality protein for tissue repair.

Choice B reason: Soybean-based hamburger with cheese offers complete proteins, with soy providing all essential amino acids (about 20 grams per patty) and cheese adding high-quality dairy protein (about 7 grams per ounce). This supports tissue repair and immune function critical for post-surgery recovery.

Choice C reason: Pasta with red sauce is primarily a carbohydrate source, with pasta offering about 5 grams of protein per cup. Red sauce contributes negligible protein. This combination is insufficient for meeting the elevated protein needs required for surgical wound healing and tissue regeneration.

Choice D reason: Baked potato with sour cream and broccoli provides limited protein (potato: ~4 grams, broccoli: ~3 grams per cup, sour cream: ~1 gram per tablespoon). This meal is primarily carbohydrate-based, lacking the high-quality protein needed for optimal post-surgery tissue repair and recovery.
