A nurse is assisting with the care of a toddler who has a septal defect and is scheduled for a cardiac catheterization. Which of the following actions should the nurse take?

A. Determine if the toddler has an allergy to iodine prior to the procedure: Cardiac catheterization typically involves the use of iodine-based contrast dye. It is crucial to determine if the toddler has an allergy to prevent any adverse reactions, during the procedure. B. Check the toddler's vital signs once each hour following the procedure: After a cardiac catheterization, vital signs should be monitored more frequently than once per hour. Typically every 15-30 minutes during the first few hours following the procedure to detect any complications. C. Give the toddler clear liquids prior to the procedure: Clear liquids are restricted before a procedure like cardiac catheterization, especially if sedation or anesthesia is involved. The child may be required to fast for several hours before the procedure to reduce the risk of aspiration. D. Administer meperidine for pain immediately following the procedure: Meperidine is not recommended for pain management in children due to its potential for side effects, including seizures. Safer alternatives, like acetaminophen or morphine, are preferred
