A nurse is reinforcing teaching with a client who is at risk for hypokalemia. The nurse should instruct the client that which of the following foods is the best source of potassium?
Spinach
Baked potato
Banana
Cheese
The Correct Answer is B
Choice A reason: Spinach is a good source of potassium, but not the best. According to the USDA, one cup of cooked spinach contains 839 mg of potassium, which is about 18% of the recommended daily intake (RDI) for adults².
Choice B reason: Baked potato is the best source of potassium among the choices. According to the USDA, one medium baked potato with skin contains 941 mg of potassium, which is about 20% of the RDI for adults². Potassium is an essential mineral that helps regulate fluid balance, nerve and muscle function, and blood pressure.
Choice C reason: Banana is a popular source of potassium, but not the best. According to the USDA, one medium banana contains 422 mg of potassium, which is about 9% of the RDI for adults².
Choice D reason: Cheese is a poor source of potassium. According to the USDA, one ounce of cheddar cheese contains only 28 mg of potassium, which is less than 1% of the RDI for adults². Cheese is high in sodium, which can counteract the benefits of potassium and increase the risk of hypertension.

Correct Answer is C
Explanation
Choice A reason: Storing oxygen tanks upright is not a necessary instruction for home oxygen therapy. Oxygen tanks can be stored horizontally or vertically, as long as they are secured and away from heat sources.
Choice B reason: Using petroleum-based ointments to moisturize lips is not advisable for clients who use home oxygen therapy. Petroleum-based products can ignite in the presence of oxygen and cause burns. The nurse should recommend water-based products instead.
Choice C reason: Keeping oxygen tanks 4 feet away from an electric stove is a safety measure for home oxygen therapy. Oxygen is a flammable gas and can cause a fire or explosion if exposed to heat or sparks. The nurse should also instruct the client to avoid smoking, candles, and other open flames.
Choice D reason: Choosing a wool blanket when using oxygen is not a good idea for home oxygen therapy. Wool is a synthetic material that can generate static electricity and ignite oxygen. The nurse should suggest cotton or other natural fabrics instead.
