Question

Quizplus · Accepted Answer

Metformin can cause lactic acidosis and renal impairment as the result of an interaction with the dye.This drug must be discontinued for 48 hours before the procedure and not started again after the procedure until urine output is well established.The client's health care provider needs to provide alternative therapy for the client until the metformin can be resumed.Keeping the client NPO,checking the client's blood glucose,and administering intravenous fluids should be part of the client's plan of care,but are not the priority,as the examination should not occur while the client is still taking metformin.
