Question

Quizplus · Accepted Answer

PTC uses iodinated dye,so the client should be asked about seafood allergies,specifically to shellfish.Documentation should occur,but this is not the priority.The client will need a ride home afterward if the procedure is done on an outpatient basis.There is no bowel preparation for PTC.
