Which food should a nurse recommend to increase a client's potassium intake?

The recommendation to increase a client's potassium intake is best addressed by choosing foods that are known to be high in potassium. While oranges do contain potassium, bananas are widely recognized as one of the richest natural sources of this important mineral. Bananas have approximately 422 mg of potassium in a medium-sized banana, which is significant compared to the amounts found in the other options.

Carrots and rice are not considered high-potassium foods, making them less suitable choices for this specific dietary need. While oranges do contain potassium, they do not match the concentration found in bananas. Therefore, in the context of recommendations for potassium intake, bananas are often the food of choice due to their high potassium content and accessibility.
