Sample item

Predictive values are most directly affected by what population factor?

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

The answer and the reasoning

D. Disease prevalence

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

Option by option

  • A. Patient height

    Patient height is not the best fit because it does not establish the requested screening conclusion.

  • B. Calendar year alone

    Calendar year alone does not explain the finding or provide the indicated intervention.

  • C. Laboratory wall color

    Laboratory wall color may be relevant elsewhere, but it conflicts with the central fact given here.

  • D. Disease prevalence (correct)

    Correct. Disease prevalence directly addresses the key clue in this scenario.
