    In healthy bodies, potassium is found in concentrations between 3.5 to 5.0 mEq per liter of blood.  It regulates water in the blood, assists in protein synthesis, and allows communication to take place between nerve cells.  Potassium is naturally found in avocados, bananas, potatoes, cantaloupe, milk, oranges, raisins, salmon, and tomatoes.  If an individual consumes some of these foods and immediately has a blood test, his potassium concentration may be above 7.0 mEq/L.  How will the body respond to this?
