Sample item

What is the role of renin in the renin-angiotensin system?

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

The answer and the reasoning

D. Initiates angiotensin generation

The core Renal physiology relationship supports Initiates angiotensin generation; it is the response that directly accounts for the structural location or physiological change described.

Option by option

  • A. Produces erythropoietin

    Produces erythropoietin does not fulfill the structural or functional role requested.

  • B. Reabsorbs glucose

    Reabsorbs glucose is not consistent with the key finding in the stem.

  • C. Directly lowers potassium

    Directly lowers potassium is associated with a different renal physiology relationship.

  • D. Initiates angiotensin generation (correct)

    Correct. Initiates angiotensin generation is directly supported by the central clue.

What is the answer to this Physiology question?

The best answer is D, Initiates angiotensin generation. The core Renal physiology relationship supports Initiates angiotensin generation; it is the response that directly accounts for the structural location or physiological change described.

Why is "Produces erythropoietin" not the answer?

Produces erythropoietin does not fulfill the structural or functional role requested.

Why is "Reabsorbs glucose" not the answer?

Reabsorbs glucose is not consistent with the key finding in the stem.

Why is "Directly lowers potassium" not the answer?

What concept does this question test?

It tests Renal physiology in Physiology. The correct option holds because: Correct. Initiates angiotensin generation is directly supported by the central clue.

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.
