A nurse is caring for a client who has acute kidney injury and has been prescribed total parenteral nutrition (TPN). When educating the client on the use of TPN, which of the following information should the nurse include?

Choice B reason: Providing low-fat carbohydrates with meals can help reduce nausea and vomiting in clients who have equilibrium imbalance. Low-fat carbohydrates are easy to digest and can provide energy and prevent hypoglycemia. Examples of low-fat carbohydrates are crackers, toast, rice, and noodles.

Choice A reason: Serving hot foods at mealtime is not a good strategy for clients who have nausea from equilibrium imbalance. Hot foods can have strong odors and flavors that can trigger nausea and vomiting. Cold or room-temperature foods are more tolerable and less stimulating for the senses.

Choice C reason: Encouraging the client to eat even if nauseated is not a helpful strategy for clients who have nausea from equilibrium imbalance. Forcing the client to eat can worsen nausea and vomiting and cause discomfort and distress. The nurse should respect the client's preferences and appetite and offer small, frequent meals and snacks.

Choice D reason: Limiting fluid intake between meals is not a necessary strategy for clients who have nausea from equilibrium imbalance. Fluid intake is important to prevent dehydration and electrolyte imbalance, which can occur due to vomiting. The nurse should encourage the client to drink fluids between meals, but avoid drinking fluids with meals, as this can cause bloating and fullness.

Choice A reason: TPN is a form of nutrition that is delivered directly into the bloodstream through a central venous catheter. It is used for clients who have impaired or nonfunctional gastrointestinal tracts, such as those with acute kidney injury, bowel obstruction, or short bowel syndrome.

Choice B reason: The TPN does not necessarily have higher levels of vitamins than the recommended daily intake. The TPN is individually tailored to meet the client's nutritional needs, which may vary depending on their condition, weight, and laboratory values.

Choice C reason: The TPN does not ensure that the client's glucose level stays within the expected range. In fact, TPN can cause hyperglycemia due to the high concentration of dextrose in the solution. The client's blood glucose level should be monitored frequently and insulin should be administered as prescribed to prevent complications.

Choice D reason: The TPN is not higher in fats and protein, but lower in carbohydrates. The TPN contains a balanced mixture of macronutrients, including carbohydrates, proteins, and lipids, as well as micronutrients, such as electrolytes, vitamins, and minerals. The ratio of these components may vary depending on the client's nutritional needs and goals.
