Sample item

What reflex responds to a sudden fall in arterial pressure?

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

The answer and the reasoning

A. Baroreceptor reflex

The core Cardiovascular physiology relationship supports Baroreceptor reflex; it is the response that directly accounts for the structural location or physiological change described.

Option by option

  • A. Baroreceptor reflex (correct)

    Correct. Baroreceptor reflex is directly supported by the central clue.

  • B. Pupillary light reflex

    Pupillary light reflex is associated with a different cardiovascular physiology relationship.

  • C. Gag reflex

    Gag reflex does not fulfill the structural or functional role requested.

  • D. Stretch reflex

    Stretch reflex is not consistent with the key finding in the stem.

What concept does this question test?

It tests Cardiovascular physiology in Physiology. The correct option holds because: Correct. Baroreceptor reflex 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 Cardiovascular 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.
