Client Education A client with type 2 diabetes is scheduled for a CT scan with intravenous (IV) contrast. The nurse is reviewing the client’s medication list and notes that the client is taking metformin. What instruction by the nurse is the priority before the procedure? Withhold the metformin for 48 hours before the CT scan. Request an order for an additional dose of metformin before the procedure. Continue the metformin as prescribed. Inform radiology that the client will need the CT scan with oral contrast instead.
