Sample item

What response is initiated when core temperature rises?

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

The answer and the reasoning

A. Sweating and cutaneous vasodilation

The relevant Thermoregulation principle makes Sweating and cutaneous vasodilation the best answer because it directly explains the structure or physiological response in the stem.

Option by option

  • A. Sweating and cutaneous vasodilation (correct)

    Correct. Sweating and cutaneous vasodilation directly follows from the core thermoregulation relationship.

  • B. Shivering

    Shivering does not correspond to the structure or response being tested.

  • C. Cutaneous vasoconstriction

    Cutaneous vasoconstriction is associated with a different anatomical or physiological role.

  • D. Increased thyroid hormone immediately

    Increased thyroid hormone immediately is not supported by the key clue provided in this item.

What concept does this question test?

It tests Thermoregulation in Physiology. The correct option holds because: Correct. Sweating and cutaneous vasodilation directly follows from the core thermoregulation 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 Thermoregulation?

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.
