Which food choice indicates a client’s understanding of potassium-rich foods to prevent digitalis toxicity?

1. Three apricots

2. Medium banana

3. Navel orange

4. Baked potato

The correct answer is: Baked potato

A baked potato is a food choice that is particularly rich in potassium, making it an excellent option for individuals at risk of digitalis toxicity. Potassium plays a crucial role in maintaining normal heart function and can help mitigate some of the potential adverse effects associated with digitalis medications, which can cause dysrhythmias if potassium levels are low. While the other options also contain potassium, their levels are not as high as that found in a baked potato. For instance, a medium banana and a navel orange do provide some potassium, but they are considered to be lower in comparison to the potassium concentrated in a baked potato. Three apricots, while they do contain potassium, also typically yield less potassium than a baked potato. Therefore, selecting a baked potato demonstrates a clear understanding of the dietary measures needed to prevent complications like digitalis toxicity through adequate potassium intake.
