The nurse is preparing a client with type 2 diabetes for a CT with contrast to evaluate diverticulitis with a possible mass. Which of the following medications on the client’s medication list would be of concern to the nurse?
Metformin must be discontinued at least 24 hours before studies with contrast media because of the risk of lactic acidosis, which can be life-threatening. Hold metformin for at least 48 hours post-procedure and do not resume therapy until kidney function has been evaluated. Fish oil is a supplement and does not pose a risk for clients undergoing CT with contrast. Coumadin is an anticoagulant and does not pose a risk with contrast. Prozac is an antidepressant and does not pose a risk with contrast.
