Sample item

Which hormone promotes sodium reabsorption in the distal nephron?

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

The answer and the reasoning

C. Aldosterone

The relevant Renal physiology principle makes Aldosterone the best answer because it directly explains the structure or physiological response in the stem.

Option by option

  • A. Prolactin

    Prolactin is associated with a different anatomical or physiological role.

  • B. Erythropoietin

    Erythropoietin is not supported by the key clue provided in this item.

  • C. Aldosterone (correct)

    Correct. Aldosterone directly follows from the core renal physiology relationship.

  • D. Calcitonin

    Calcitonin does not correspond to the structure or response being tested.
