Potassium is a severe tissue irritant. The safest action is to discontinue the solution that contains the potassium and discontinue the IV altogether, in which case the client would need another site started. Assessing for a blood return may or may not be successful. The solution could be diluted (less potassium) and the rate could be slowed once it is determined that the needle is in the vein.
