Which instruction will the nurse provide to a patient taking metformin who is scheduled for an angiogram? “Call the health care provider and ask for a temporary change in antidiabetic agent.” “Cancel the angiogram as the procedure is contraindicated when using metformin.” “Take the medication before the angiogram but do not take it afterward for 48 hours.” “Avoid taking the medication for 24 hours prior to the angiogram and resume once able to urinate.”
