A nurse is providing dietary advice to a patient at risk for hypokalemia.
Which food should the nurse recommend as a good source of potassium?

Choice A rationale:

Petroleum-based ointments like Vaseline are not recommended for moisturizing lips, especially for patients on oxygen therapy. This is because petroleum jelly is not effective at restoring moisture once it’s been lost. Moreover, it can feel heavy and slippery on the lips, and it’s not very eco-friendly.

Choice B rationale:

Oxygen tanks should be kept at a safe distance from heat sources, including electric stoves. However, the recommended distance is not 4 feet but rather at least 5-10 feet away. This is to minimize the risk of fire or combustion.

Choice C rationale:

Wool blankets are not recommended when using oxygen. Wool can cause a spark which can be dangerous around oxygen. It’s important to avoid anything that may cause a spark around home oxygen, including electric heaters, electric blankets, electric razors, hair dryers, or friction toys.

Choice D rationale:

Oxygen tanks should always be stored upright. This prevents any strain on the valves or other components and reduces the risk of damage and potential gas leaks.

Choice A rationale:

Hypertension is not typically a sign of hypokalemia. Hypokalemia, or low potassium levels, can cause symptoms like fatigue, muscle weakness, digestive problems, and frequent urination. Hypertension, or high blood pressure, is not commonly associated with hypokalemia.

Choice B rationale:

Cerebral edema, or swelling in the brain, is not a common symptom of hypokalemia. Hypokalemia is more likely to cause symptoms related to muscle function and digestion, as potassium is an essential mineral that helps regulate muscle contractions, maintain healthy nerve function, and regulate fluid balance.

Choice C rationale:

Muscle weakness is a common symptom of hypokalemia. Potassium helps regulate muscle contractions. When blood potassium levels are low, your muscles produce weaker contractions. This can result in symptoms like muscle weakness and fatigue.

Choice D rationale:

Hyperactive bowel sounds are not typically associated with hypokalemia. Hypokalemia can cause digestive problems, but these are more likely to be issues like constipation rather than increased bowel sounds.
