The nurse is preparing to administer amphotericin b (fungizone) iv to a client. what laboratory data is most important for the nurse to assess before initiating an iv infusion of this medication?

The nurse should obtain baseline potassium levels prior to beginning drug therapy because amphotericin (Fungizone) changes cellular permeability, allowing potassium to escape from the cell, which could lead to a decrease in the serum potassium level and severe hypokalemia. :)
