ARRT Patient Care Practice Exam

What should be done first if a radiographer suspects a patient has a perforated ulcer during a GI series?

1. Continue with the examination

2. Administer thick barium sulfate

3. Switch to water-soluble iodinated media

4. Notify the physician immediately

The correct answer is: Switch to water-soluble iodinated media

When a radiographer suspects a patient has a perforated ulcer during a gastrointestinal (GI) series, the first step should be to switch to water-soluble iodinated media. This is crucial because if there is a perforated ulcer, using a thick barium sulfate can lead to serious complications. Barium is not easily absorbed by body tissues and can cause peritonitis if it leaks into the abdominal cavity through a perforation. Water-soluble iodinated contrast media is safer in this scenario, as it is absorbed by the body and can help minimize any potential risks associated with a perforation. The use of this media allows for the examination to continue while ensuring the patient's safety is prioritized. This approach provides valuable diagnostic information without increasing the risk of further complications. Other steps, like notifying the physician and administering a specific type of contrast, should follow after ensuring that the safest contrast medium is utilized. The immediate action of selecting the appropriate contrast helps in efficiently managing the patient's condition while awaiting further medical advice or intervention.
