The nurse is preparing the client for a computed tomography (CT) scan of the abdomen with IV contrast. Which question does the nurse ask the client before the examination?
a. "Are you allergic to shrimp, scallops, or shellfish?"
b. "Have you had anything to eat or drink in the past 12 hours?"
c. "Did you finish taking all the prescribed laxatives?"
d. "Can you tolerate being tilted from side to side?"
A
Allergies to iodine or seafood can cause a cross-allergic reaction to the contrast dye used for CT scans. Clients reporting such allergies should be scheduled for CT without contrast to avoid anaphylactic reactions. The client does not need to be NPO for this test and does need not to take laxatives. The client is not tilted during the CT scan.
