Sample item

What is the main process that creates glomerular filtrate?

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

The answer and the reasoning

C. Ultrafiltration

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

Option by option

  • A. Tubular secretion

    Tubular secretion does not correspond to the structure or response being tested.

  • B. Peristalsis

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

  • C. Ultrafiltration (correct)

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

  • D. Active reabsorption

    Active reabsorption is associated with a different anatomical or physiological role.

How hard is this question?

We tag it as an application question: it asks you to use a fact on a patient or a finding. The tag is our own editorial judgement, not an official difficulty rating, so read the reason for every option, not only the answer.

How should I study Renal physiology?

For each system, sketch the key graph (pressure–volume loop, oxygen dissociation curve, nephron handling) and explain it aloud. Then use the flashcards and the other Physiology questions on this site to test what stuck.

Is this a real NEET PG question?

No. It is an original practice item (editorial status: sample, version 1). NextPrep does not publish recalled or leaked questions, and independent faculty review of this item has not been completed yet, so confirm important facts in a standard textbook.
