Simulated
The nurse is caring for a client scheduled for a computed tomography (CT) scan with contrast. The nurse recognizes which medication should be held after the procedure?
Correct answer
B
Rationale
Metformin should be held after a CT scan with contrast due to the risk of lactic acidosis if contrast-induced nephropathy occurs. Labetalol, levodopa, and ondansetron are not affected by contrast.
