A nurse is teaching a client who has chronic kidney disease about limiting foods that are high in potassium. Which of the following foods should the nurse instruct the client to avoid? (Select all that apply)
Raisins
Asparagus
Bananas
Tomatoes
Green Beans
Correct Answer : A,C,D
Choice A reason:
Raisins are dried grapes and are known to have a higher concentration of nutrients, including potassium. For individuals with chronic kidney disease (CKD), consuming foods like raisins that are high in potassium can lead to hyperkalemia, a condition where potassium levels in the blood are higher than normal. This can be dangerous as it may cause heart rhythm problems.
Choice B reason:
Asparagus is considered a lower-potassium food, making it a safer choice for people with CKD. It's important for individuals with CKD to manage their potassium intake, but asparagus can be included in their diet in appropriate portions.
Choice C reason:
Bananas are well-known for being rich in potassium. For someone with CKD, eating bananas can contribute to an excessive intake of potassium, which their kidneys may not be able to eliminate efficiently, potentially leading to hyperkalemia.
Choice D reason:
Tomatoes, including tomato products like sauces, juices, and purees, are high in potassium. Therefore, they should be limited or avoided in the diet of a person with CKD to prevent complications associated with high potassium levels.
Choice E reason:
Green beans are considered to be a lower-potassium vegetable. They can be included in a kidney-friendly diet, provided they are consumed in moderation and balanced with other dietary needs.

Correct Answer is C
Explanation
Choice A reason:
Lightheadedness is generally not an indication of effective treatment for dehydration. It is often a symptom of dehydration itself, as it can result from decreased blood volume and reduced blood flow to the brain. Effective rehydration should alleviate symptoms like lightheadedness, not present as an indication of it.
Choice B reason:
Decreased pulse pressure may indicate a drop in the volume of blood circulating through the body, which is not a sign of effective rehydration. Pulse pressure is the difference between systolic and diastolic blood pressure readings, and a narrow pulse pressure can be a sign of hypovolemia, or low blood volume, often due to dehydration.
Choice C reason:
Urine output of 75 mL in 1 hr can be considered within the normal range of urine output for an adult, which is typically about 0.5 to 1 mL/kg/hr⁵. This indicates that the kidneys are functioning and the body is excreting waste, suggesting effective rehydration.
Choice D reason:
A urine specific gravity of 1.038 is higher than the normal range of 1.005 to 1.030[^10^]. This indicates concentrated urine, which is commonly seen in dehydration as the body attempts to conserve water. Therefore, this is not an indication of effective treatment for dehydration.
Correct Answer is C
Explanation
Choice A reason:
While metabolic syndrome is associated with several health issues, it is not a direct risk factor for hyperthyroidism. Metabolic syndrome typically includes conditions like insulin resistance, hypertension, and dyslipidemia, which are more closely related to diabetes and cardiovascular diseases rather than thyroid function.
Choice B reason:
An iodine deficiency is commonly associated with hypothyroidism, not hyperthyroidism. Iodine is essential for the production of thyroid hormones, and a lack of it can lead to decreased hormone production and an underactive thyroid.
Choice C reason:
Graves' disease is the most common cause of hyperthyroidism. It is an autoimmune disorder where the immune system mistakenly attacks the thyroid gland, causing it to produce too much thyroid hormone. A 35-year-old male with Graves' disease would indeed be at high risk for hyperthyroidism.
Choice D reason:
While a family history of autoimmune disorders can increase the risk of developing autoimmune-related hyperthyroidism, it is not as direct a risk factor as having Graves' disease itself. Autoimmune disorders can have a genetic component, but having a family history does not guarantee the development of hyperthyroidism.
