Sample item

Which contrast is generally avoided when gastrointestinal perforation is suspected?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Barium sulfate

If perforation is possible, leaked barium can cause severe inflammatory complications, so water-soluble contrast is generally preferred when contrast imaging is required.

Option by option

  • A. Barium sulfate (correct)

    Correct: barium is avoided when perforation may allow leakage.

  • B. Ultrasound gel

    Ultrasound gel is external and not ingested contrast.

  • C. Water-soluble iodinated contrast

    Water-soluble iodinated contrast is usually preferred in this setting.

  • D. Normal saline

    Normal saline is not a routine gastrointestinal radiographic contrast agent.
