Sample item

What is the major determinant of arterial blood pressure?

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

The answer and the reasoning

D. Cardiac output and peripheral resistance

The relevant Cardiovascular physiology principle makes Cardiac output and peripheral resistance the best answer because it directly explains the structure or physiological response in the stem.

Option by option

  • A. Plasma glucose

    Plasma glucose is associated with a different anatomical or physiological role.

  • B. Lung compliance only

    Lung compliance only is not supported by the key clue provided in this item.

  • C. Hemoglobin alone

    Hemoglobin alone does not correspond to the structure or response being tested.

  • D. Cardiac output and peripheral resistance (correct)

    Correct. Cardiac output and peripheral resistance directly follows from the core cardiovascular physiology relationship.

What concept does this question test?

It tests Cardiovascular physiology in Physiology. The correct option holds because: Correct. Cardiac output and peripheral resistance directly follows from the core cardiovascular physiology relationship.

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.
