A client diagnosed with type II diabetes controlled with a biguanide medication and a history of liver disease is scheduled for a computed tomography (CT) scan with contrast medium of the abdomen to evaluate pancreatic function.
Which intervention should the nurse implement?
Administer a laxative to cleanse the bowel before the CT scan.
Administer the biguanide medication as scheduled.
Advise the client to fast for 24 hours before the CT scan.
Ensure the client is adequately hydrated before the CT scan.
The Correct Answer is D
Choice A rationale
Administering a laxative is not necessary for a CT scan of the abdomen with contrast. Laxatives are typically used for bowel preparation for procedures like colonoscopies.
Choice B rationale
Biguanide medications such as metformin should be held before and after the administration of contrast medium to prevent lactic acidosis, particularly in clients with liver disease.
Choice C rationale
Fasting for 24 hours is not required before a CT scan with contrast medium. Typically, clients are asked to fast for a few hours prior to the procedure.
Choice D rationale
Ensuring the client is adequately hydrated helps to protect kidney function and reduce the risk of contrast-induced nephropathy. Hydration is especially important for clients with a history of liver disease.
