electrolyte solution, any solution containing electrolytes prepared for oral, parenteral, or rectal administration for the replacement or supplementation of ions necessary for homeostasis. The loss of potassium ion (K+) by vomiting, by diarrhea, or by the action of certain medications, including diuretics and corticosteroids, may be corrected by administering a solution high in potassium. Other electrolyte solutions containing combinations of sodium, potassium, calcium, magnesium, chloride, bicarbonate, phosphate, and/or lactate may be given to treat acid-base disturbance, as seen in chronic renal dysfunction or diabetic ketoacidosis. The solutions are available in a wide range of balanced formulas for replacement or maintenance, and most include various trace minerals.
