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?
The TPN is needed to bypass your gastrointestinal tract.
The TPN will have higher levels of vitamins than the recommended daily intake.
The TPN will ensure that your glucose level stays within the expected range.
The TPN will be higher in fats and protein, but lower in carbohydrates.
The Correct Answer is A
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.

Correct Answer is D
Explanation
Choice D reason: Tuna is a good source of iodine, which is a mineral that is essential for the production of thyroid hormones. A goiter is an enlargement of the thyroid gland that can be caused by iodine deficiency. Eating more iodine-rich foods, such as tuna, can help prevent or treat a goiter.
Choice A reason: Red meat is not a good source of iodine, and it can also be high in saturated fat and cholesterol, which can increase the risk of heart disease and other health problems. Eating more red meat is not advisable for a client who has a goiter.
Choice B reason: Blueberries are not a good source of iodine, and they have no direct effect on the thyroid gland or a goiter. Blueberries are rich in antioxidants and other nutrients, but they are not a specific food choice for a client who has a goiter.
Choice C reason: Bananas are not a good source of iodine, and they have no direct effect on the thyroid gland or a goiter. Bananas are a good source of potassium and fiber, but they are not a specific food choice for a client who has a goiter.
Correct Answer is B
Explanation
Choice A reason: Bran cereal is high in phosphorus, containing about 34% of the DV per cup (118 g) ( 1 ). Phosphorus is a mineral that helps build strong bones and teeth, but too much of it can cause problems for people with kidney disease. The kidneys normally filter out excess phosphorus from the blood, but when they are damaged, phosphorus can build up and cause bone loss, itching, and calcification of blood vessels and organs ( 2 ).
Choice B reason: A medium apple is low in phosphorus, containing only 3% of the DV per 182 g ( 3 ). Apples are also a good source of fiber, vitamin C, and antioxidants. They can help lower blood pressure, cholesterol, and blood sugar levels, which are beneficial for people with kidney disease ( 4 ).
Choice C reason: Scrambled eggs are moderate in phosphorus, containing about 12% of the DV per large egg (50 g) ( 5 ). Eggs are also high in protein, which can increase the workload of the kidneys and worsen kidney function. People with kidney disease should limit their protein intake to 0.8 g per kg of body weight per day, unless advised otherwise by their doctor ( 6 ).
Choice D reason: Ground turkey is high in phosphorus, containing about 16% of the DV per 3 oz (85 g) ( 7 ). Ground turkey is also high in protein, which can have the same negative effects as eggs on kidney function. People with kidney disease should choose lean meats and poultry, and eat them in moderation.
