Simulated
A client is scheduled for a spiral computed tomography (CT) scan with contrast to evaluate for pulmonary embolism. Which information in the client's history requires follow-up by the nurse?
Correct answer
A
Rationale
Metformin increases the risk of lactic acidosis with contrast agents, requiring follow-up to hold the drug. Metal prostheses, prior CT scans, and sobriety are less critical for contrast safety.
