The nurse is caring for a client who is taking metformin (Glucophage) for hyperglycemia prior to admission. The nurse would question the following order for this client:
Correct answer
A
Rationale
The correct answer is A: CT scan with contrast. Metformin can cause lactic acidosis when combined with contrast dye, so it is contraindicated. The other options (B: Chest X-ray 1 view, C: V/Q scan, D: Bilateral lower extremity ultrasound) do not involve the use of contrast dye and are safe to proceed with for a client taking metformin. It is crucial to avoid potentially harmful drug interactions to ensure the client's safety.
