Sample item

What can reduce risk from contrast-associated kidney injury in appropriate patients?

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

The answer and the reasoning

A. Hydration and risk assessment

The central Contrast safety principle supports Hydration and risk assessment; it is the answer that most directly explains the image finding, modality choice, or oral-health feature described.

Option by option

  • A. Hydration and risk assessment (correct)

    Correct. Hydration and risk assessment best matches the key information in this scenario.

  • B. Avoiding vital signs

    Avoiding vital signs is not supported by the imaging or dental clue provided.

  • C. Immediate fasting for days

    Immediate fasting for days does not fit the stated contrast safety context.

  • D. Routine antibiotic use

    Routine antibiotic use may be used elsewhere but is not the strongest answer here.
