A nurse is preparing to administer daily medications to a client who is undergoing a procedure at 1000 that requires IV contrast dye. Which of the following routine medications to give at 0800 should the nurse withhold?
Fluticasone
Valproic acid
Metformin
Metoprolol
The Correct Answer is C
Metformin is an oral medication used to treat type 2 diabetes. It should be withheld before and after a procedure that requires IV contrast dye because it can increase the risk of lactic acidosis, a serious condition caused by the buildup of lactic acid in the blood. The other medications are not contraindicated with IV contrast dye and can be given as scheduled.

The other options are not appropriate because they violate the client's autonomy and dignity.
