Sample item

Which drug reduces uric acid formation by inhibiting xanthine oxidase?

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

The answer and the reasoning

C. Allopurinol

The defining Nucleotide metabolism relationship supports Allopurinol; it is the option that most directly explains the biochemical pathway or pathological process in the stem.

Option by option

  • A. Furosemide

    Furosemide is relevant in a different context but is not supported here.

  • B. Metformin

    Metformin does not account for the central finding in this item.

  • C. Allopurinol (correct)

    Correct. Allopurinol is the appropriate conclusion from the key feature.

  • D. Aspirin

    Aspirin does not match the stated nucleotide metabolism mechanism.
