A client is scheduled for a spiral computed topography (CT) scan with contrast to evaluate for pulmonary embolism. Which information in the client’s history requires follow-up by the nurse?

Metformin is a medication that can affect kidney function. Since contrast dye used in CT scans is processed through the kidneys, it is important for the nurse to follow up on the client’s use of metformin before the CT scan with contrast. The client may need to temporarily stop taking metformin before and after the procedure to prevent any potential harm to their kidneys.
