A nurse is reinforcing teaching with a client about following a low-cholesterol diet after coronary artery bypass grafting. Which of the following food choices reflects the client's understanding of these dietary instructions?

A. Provide a diet high in protein.

During the oliguric phase of acute kidney injury (AKI), there is a risk of electrolyte imbalances, including elevated levels of blood urea nitrogen (BUN) and creatinine. Restricting protein intake is often recommended during this phase to manage azotemia and prevent the accumulation of waste products that the kidneys may struggle to excrete.

B. Provide ibuprofen for retroperitoneal discomfort.

Ibuprofen and other nonsteroidal anti-inflammatory drugs (NSAIDs) are contraindicated in AKI. They can further compromise renal function and may contribute to acute tubular necrosis. NSAIDs can also affect renal blood flow, leading to worsening kidney function.

C. Monitor intake and output hourly.

Monitoring intake and output (I&O) is a critical nursing intervention during the oliguric phase of AKI. Hourly monitoring helps assess renal function, fluid balance, and the effectiveness of interventions. It allows for early detection of changes that may require prompt intervention.

D. Encourage the client to consume at least 2 L of fluid daily.

In the oliguric phase of AKI, fluid intake is often restricted to prevent fluid overload. Encouraging excessive fluid intake may contribute to fluid retention and worsen the oliguria. Fluid management is carefully regulated based on the individual client's needs and renal function.

A. Kidney beans

Kidney beans are a good plant-based source of protein. They contain essential amino acids, but plant-based proteins may lack some amino acids found in animal-based sources. While kidney beans contribute to protein intake, they are not considered the best source of protein for wound healing among the given options.

B. Grilled salmon

Grilled salmon is indicated as the best source of protein for wound healing among the options. Salmon is an animal-based source that provides high-quality protein with all essential amino acids. It is also rich in omega-3 fatty acids, which have anti-inflammatory properties and can further support the healing process.

C. Peanut butter

Peanut butter is a source of protein, but it is also high in fats. While it can contribute to protein intake, it may not be as lean a source as grilled salmon. It's important to consider the overall nutritional profile when recommending it for wound healing.

D. Raw spinach

Spinach is a source of protein, but it is considered a plant-based protein. While it can contribute to overall protein intake, plant-based proteins may not provide as much protein per serving as animal-based sources like salmon. It also contains other nutrients, such as iron and vitamins, which are beneficial but not specifically highlighted for wound healing in this context.
