A nurse is teaching about food choices to a client who has chronic kidney disease and must limit potassium intake. Which of the following choices should the nurse recommend as containing the least potassium?
1 cup white rice
1/2 cup nonfat yogurt
1 medium baked potato with skin
2 tbsp peanut butter
The Correct Answer is A
Choice A reason: White rice is considered a low-potassium food, making it a suitable option for someone with chronic kidney disease who needs to limit their potassium intake. One cup of cooked white rice contains approximately 54 mg of potassium, which is significantly lower than the other options listed.
Choice B reason: Nonfat yogurt can vary in potassium content, but on average, a 1/2 cup serving may contain around 200 to 300 mg of potassium. While it is a nutritious choice, it contains more potassium than white rice and should be consumed in moderation by individuals with potassium restrictions.
Choice C reason: A medium baked potato with skin is high in potassium, with one potato containing over 900 mg of potassium. This makes it an unsuitable choice for someone who needs to limit their potassium intake due to chronic kidney disease.
Choice D reason: Peanut butter contains a moderate amount of potassium. Two tablespoons of peanut butter can have around 150 to 200 mg of potassium. Although it's not as high in potassium as a baked potato, it still contains more potassium than white rice.

Correct Answer is C
Explanation
Choice A reason : A blood pressure of 138/76 mm Hg is within the higher range of normal and is not typically considered an adverse effect of metoprolol, which is used to lower blood pressure.
Choice B reason : A temperature of 36.3°C (97.3°F) is within the normal range and is not an adverse effect of metoprolol.
Choice C reason : A heart rate of 48/min is considered bradycardia and can be an adverse effect of metoprolol, which is a beta-blocker that can slow down the heart rate.
Choice D reason : A respiratory rate of 10/min is on the lower end of the normal range but is not a typical adverse effect of metoprolol. However, if the patient shows signs of respiratory distress, it should be addressed.
Correct Answer is A
Explanation
Choice A reason: Administering prednisone before the test may be part of a premedication protocol for clients with a history of allergic reactions to contrast media. However, this is typically done for iodinated contrast used in CT scans, not for gadolinium-based contrast agents used in MRA.
Choice B reason: Consulting with the provider to change to a CT scan would not be appropriate if the client is allergic to iodinated contrast dye, as CT scans commonly use iodinated contrast. MRA typically uses gadolinium-based contrast agents, which may be safer for clients with iodine allergies.
Choice C reason: Assessing the alkaline phosphatase level is not directly related to preparing a client with a contrast dye allergy for an MRA. Alkaline phosphatase is an enzyme measured in blood tests and is not specific to contrast media allergies.
Choice D reason: Obtaining the client's allergy history to seafood is not necessary for MRA preparation. While there is a common misconception that seafood allergies are related to iodinated contrast allergies, the evidence does not support this association.
