Sample item

Which test property helps confirm disease after a positive result?

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

The answer and the reasoning

B. High specificity

This Screening item is resolved by the defining principle: High specificity best matches the stated finding or public-health measure.

Option by option

  • A. Low prevalence

    Low prevalence may be relevant elsewhere, but it conflicts with the central fact given here.

  • B. High specificity (correct)

    Correct. High specificity directly addresses the key clue in this scenario.

  • C. Low negative predictive value

    Low negative predictive value does not explain the finding or provide the indicated intervention.

  • D. High sensitivity

    High sensitivity is not the best fit because it does not establish the requested screening conclusion.
