A nurse is providing teaching about the Dietary Approaches to Stop Hypertension (DASH) diet to a client who has hypertension. Which of the following instructions should the nurse include?

Choice A reason: Drinking orange juice with iron supplements can increase absorption, not decrease it. Orange juice is rich in vitamin C, which enhances the absorption of non-heme iron, the type of iron found in plant foods and supplements. The nurse should advise the client to take iron supplements with a source of vitamin C, such as orange juice, strawberries, or tomatoes.

Choice B reason: Cooking in a stainless steel skillet does not increase the amount of iron in the food. Stainless steel is not a good conductor of iron and does not leach iron into the food. The nurse should suggest the client to use a cast iron skillet instead, which can add iron to the food, especially acidic foods like tomatoes or citrus fruits.

Choice C reason: Drinking iced tea with meals can decrease the amount of iron absorbed, not increase it. Iced tea contains tannins, which are compounds that bind to iron and inhibit its absorption. The nurse should recommend the client to avoid drinking tea, coffee, or other beverages that contain tannins with meals, and to drink them between meals instead.

Choice D reason: Fish and poultry are primary sources of heme iron, which is the type of iron found in animal foods and is more easily absorbed by the body. The nurse should encourage the client to eat more foods that are high in heme iron, such as fish, poultry, meat, and eggs.

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.
