Sample item

Which patient factor increases concern for iodinated contrast-associated kidney injury and warrants risk assessment?

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

The answer and the reasoning

B. Severely reduced baseline renal function

Severely impaired baseline kidney function increases concern around iodinated contrast use, so the clinical benefit, alternative imaging, hydration status, medication context, and local protocol should be considered before administration.

Option by option

  • A. A healed finger fracture

    A healed fracture does not change contrast nephrotoxicity risk.

  • B. Severely reduced baseline renal function (correct)

    Correct: low baseline renal function is an important contrast risk factor.

  • C. Mild seasonal rhinitis

    Seasonal rhinitis is not a typical kidney-risk factor for contrast decisions.

  • D. Normal visual acuity

    Visual acuity does not determine iodinated contrast renal risk.

What is the answer to this Radiology question?

The best answer is B, Severely reduced baseline renal function. Severely impaired baseline kidney function increases concern around iodinated contrast use, so the clinical benefit, alternative imaging, hydration status, medication context, and local protocol should be considered before administration.

Why is "A healed finger fracture" not the answer?

A healed fracture does not change contrast nephrotoxicity risk.

Why is "Mild seasonal rhinitis" not the answer?

Seasonal rhinitis is not a typical kidney-risk factor for contrast decisions.

Why is "Normal visual acuity" not the answer?

Visual acuity does not determine iodinated contrast renal risk.

What concept does this question test?

It tests Contrast safety in Radiology. The correct option holds because: Correct: low baseline renal function is an important contrast risk factor.

How hard is this question?

We tag it as an application question: it asks you to use a fact on a patient or a finding. The tag is our own editorial judgement, not an official difficulty rating, so read the reason for every option, not only the answer.

How should I study Contrast safety?

Learn signs with the image, and the disease they point to. Then use the flashcards and the other Radiology questions on this site to test what stuck.

Is this a real NEET PG question?

No. It is an original practice item (editorial status: sample, version 1). NextPrep does not publish recalled or leaked questions, and independent faculty review of this item has not been completed yet, so confirm important facts in a standard textbook.
