The diabetic client is scheduled for a computed tomography (CT) scan with intravenous contrast. What education will the nurse provide? (Select all that apply.)

Hold metformin 24 hours to 48 hours before the CT.

Hold metformin 48 hours after the CT.

Double the metformin dose after the CT.

Take metformin as scheduled the day of the CT.

Resume metformin at half dose after the CT.

Answer and Explanation

Correct Answer : A,B

A) Hold metformin 24 hours to 48 hours before the CT. This is correct because it reduces the chance of metformin accumulating in the blood and causing lactic acidosis when combined with the contrast dye.

B) Hold metformin 48 hours after the CT. This is also correct because it allows time for the contrast dye to be eliminated from the body before resuming metformin.

C) Double the metformin dose after the CT. This is incorrect and dangerous because it can cause hypoglycemia, low blood sugar, which can lead to confusion, seizures, coma, or death. D) Take metformin as scheduled the day of the CT. This is incorrect and risky because it can result in high levels of metformin in the blood when mixed with the contrast dye, increasing the likelihood of lactic acidosis.

E) Resume metformin at half dose after the CT. This is incorrect and unnecessary because there is no evidence that reducing the dose of metformin after a CT scan with contrast dye has any benefit or reduces any harm.
