Sample item

Which phase includes isovolumetric contraction?

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

The answer and the reasoning

B. Early ventricular systole

This item reviews Cardiac cycle; Early ventricular systole is the best answer because it directly fits the anatomical or physiological relationship described.

Option by option

  • A. Rapid filling only

    Rapid filling only is not supported by the key finding.

  • B. Early ventricular systole (correct)

    Correct. Early ventricular systole matches the defining feature.

  • C. Atrial systole only

    Atrial systole only does not match the stated relationship.

  • D. Ventricular diastole only

    Ventricular diastole only is plausible but is not the best answer.

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 Cardiac cycle?

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.
