Sample item

What is potency best reflected by?

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

The answer and the reasoning

C. Dose needed to produce an effect

The central Pharmacodynamics concept identifies Dose needed to produce an effect as the best answer because it directly explains the mechanism, indication, adverse effect, or organism feature described.

Option by option

  • A. Maximum possible response

    Maximum possible response does not fit the stated pharmacodynamics relationship.

  • B. Elimination route

    Elimination route is unsupported by the mechanism or clinical clue in the stem.

  • C. Dose needed to produce an effect (correct)

    Correct. Dose needed to produce an effect matches the decisive point in this scenario.

  • D. Drug color

    Drug color has another context but is not the most appropriate answer here.
