Sample item

What hormone is produced by kidney cells in response to hypoxia?

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

The answer and the reasoning

A. Erythropoietin

Renal peritubular cells release erythropoietin in response to reduced oxygen delivery, stimulating erythroid precursor production in bone marrow.

Option by option

  • A. Erythropoietin (correct)

    Correct: erythropoietin is the renal response to tissue hypoxia.

  • B. Insulin

    Insulin is produced by pancreatic beta cells.

  • C. Thyroxine

    Thyroxine is produced by thyroid follicular cells.

  • D. Oxytocin

    Oxytocin is released from the posterior pituitary.

What is the answer to this Physiology question?

The best answer is A, Erythropoietin. Renal peritubular cells release erythropoietin in response to reduced oxygen delivery, stimulating erythroid precursor production in bone marrow.

Why is "Insulin" not the answer?

Insulin is produced by pancreatic beta cells.

Why is "Thyroxine" not the answer?

Thyroxine is produced by thyroid follicular cells.

Why is "Oxytocin" not the answer?

Oxytocin is released from the posterior pituitary.

What concept does this question test?

It tests Renal physiology in Physiology. The correct option holds because: Correct: erythropoietin is the renal response to tissue hypoxia.

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.
