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 A reason: Increasing the caloric intake before pregnancy is not an appropriate dietary guideline, as it can lead to excessive weight gain and obesity, which can increase the risk of gestational diabetes, hypertension, and other complications. The nurse should advise the client to maintain a healthy weight and a balanced diet before and during pregnancy.

Choice B reason: Increasing the total intake of seafood to 20 ounces per week is not an appropriate dietary guideline, as it can expose the client to high levels of mercury, which can harm the developing fetus. The nurse should advise the client to limit the intake of seafood to 8 to 12 ounces per week, and avoid fish that are high in mercury, such as shark, swordfish, and king mackerel.

Choice C reason: Decreasing ascorbic acid in the diet is not an appropriate dietary guideline, as it can impair the immune system and the absorption of iron, which are both important for the health of the mother and the fetus. The nurse should advise the client to consume adequate amounts of ascorbic acid, which is found in citrus fruits, tomatoes, broccoli, and other foods.

Choice D reason: Increasing folic acid to 400 micrograms per day prior to getting pregnant is an appropriate dietary guideline, as it can prevent neural tube defects, such as spina bifida and anencephaly, in the fetus. The nurse should advise the client to take a daily prenatal vitamin that contains folic acid, and eat foods that are rich in folate, such as leafy greens, beans, and fortified cereals.

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.
