Correct Answer:
Takes metformin hydrochloride for type 2 diabetes mellitus.
Rationale:
🔶 Metformin combined with iodinated contrast used in CT scans increases the risk of lactic acidosis, especially in clients with impaired renal function.
🔶 It is crucial to withhold metformin before and after contrast administration until renal function is confirmed as stable.
🔶 Lactic acidosis can be life-threatening and may present subtly, so risk prevention is critical during imaging procedures.
🔶 The nurse must follow up with the provider to determine if creatinine clearance has been assessed or if alternative imaging is needed.
