Sample item

During moderate exercise, what happens to cardiac output?

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

The answer and the reasoning

D. It increases

The relevant Exercise physiology principle makes It increases the best answer because it directly explains the structure or physiological response in the stem.

Option by option

  • A. It falls to zero

    It falls to zero does not correspond to the structure or response being tested.

  • B. It remains fixed

    It remains fixed is associated with a different anatomical or physiological role.

  • C. It becomes independent of heart rate

    It becomes independent of heart rate is not supported by the key clue provided in this item.

  • D. It increases (correct)

    Correct. It increases directly follows from the core exercise physiology relationship.
