A nurse is assisting in the selection of food for a client who has hypokalemia. Which of the following foods should the nurse select that contains the greatest amount of potassium?
1 oz of cheddar cheese.
One medium raw tomato.
1 cup of brown rice.
One small baked potato.
The Correct Answer is D
Choice A rationale:
Cheddar cheese does not contain a significant amount of potassium. It is a dairy product that is richer in calcium and fat than in potassium.
Choice B rationale:
Raw tomato contains some potassium, but it's not as high as the other options. It's a good source of vitamins and antioxidants, but for hypokalemia, more potassium-rich options are better.
Choice C rationale:
Brown rice contains moderate levels of potassium, but it is not as high as the potassium content in a baked potato.
Choice D rationale:
One small baked potato is a great source of potassium. Potatoes are known for their high potassium content, making them suitable for individuals with hypokalemia, as potassium is essential for proper muscle and nerve function.

Correct Answer is B
Explanation
The correct answer is choice B. “Consume foods that are high in calcium.”
Choice A rationale:
The DASH diet recommends limiting sodium intake to no more than 2,300 milligrams per day, and ideally to 1,500 milligrams per day for greater blood pressure reduction. Therefore, 3,200 milligrams per day is too high.
Choice B rationale:
Consuming foods high in calcium is part of the DASH diet, which emphasizes the intake of fruits, vegetables, and low-fat dairy products to help lower blood pressure.
Choice C rationale:
The DASH diet advises reducing saturated fat intake to less than 6% of total daily calories. Ten percent is higher than recommended.
Choice D rationale:
The DASH diet encourages the consumption of whole grains and discourages refined carbohydrates, which can contribute to higher blood pressure and other health issues.

Correct Answer is D
Explanation
Choice A rationale:
1 cup cooked green peppers. Green peppers are a good source of vitamin C but do not contain a significant amount of folate. Folate is important for preventing neural tube defects in a developing fetus.
Choice B rationale:
1 cup mashed potatoes. While potatoes contain some folate, especially in their skins, they do not have as high an amount as other options. Additionally, mashed potatoes may not retain all of their folate content after cooking and preparation.
Choice C rationale:
1 cup cooked carrots. Carrots are not a substantial source of folate. They are more known for their beta-carotene content, which is converted into vitamin A in the body.
Choice D rationale:
1 cup cooked lentils. Lentils are an excellent source of folate, providing a substantial amount per serving. Folate is essential for preventing neural tube defects in the early stages of pregnancy. Including folate-rich foods like lentils in the diet can be highly beneficial for individuals planning to become pregnant.
