Sample item

What is the appropriate immediate response to suspected contrast extravasation at an injection site?

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

The answer and the reasoning

B. Stop the injection and assess the affected limb

If contrast extravasation is suspected, injection should stop immediately and the site should be assessed for pain, swelling, neurovascular compromise, and skin risk, with management following local contrast-safety protocol.

Option by option

  • A. Continue rapidly to finish the scan

    Continuing injection can increase tissue injury from extravasated contrast.

  • B. Stop the injection and assess the affected limb (correct)

    Correct: stopping injection and assessing the limb limits further injury.

  • C. Ignore swelling if the patient is calm

    Visible swelling requires assessment even if the patient seems calm.

  • D. Apply a tourniquet above the site indefinitely

    An indefinite tourniquet is not routine extravasation management.
