Sample item

What feature is especially concerning for methanol poisoning?

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

The answer and the reasoning

A. Visual disturbance with high-anion-gap metabolic acidosis

Methanol is metabolized to formate, which can produce severe high-anion-gap metabolic acidosis and optic toxicity causing blurred vision or visual loss; urgent antidotal and supportive treatment is required.

Option by option

  • A. Visual disturbance with high-anion-gap metabolic acidosis (correct)

    Correct: acidosis with visual toxicity strongly suggests methanol exposure.

  • B. Isolated painless skin peeling

    Skin peeling alone is not the characteristic methanol presentation.

  • C. Improved vision after ingestion

    Methanol endangers rather than improves vision.

  • D. Marked eosinophilia only

    Eosinophilia is not the key diagnostic metabolic finding.
