Sample item

Which plasma protein is the major determinant of oncotic pressure?

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

The answer and the reasoning

D. Albumin

Albumin is abundant in plasma and provides most colloid oncotic pressure, helping retain fluid within the intravascular compartment.

Option by option

  • A. Immunoglobulin E

    IgE is a low-concentration antibody.

  • B. Haemoglobin

    Haemoglobin is contained within red cells.

  • C. Fibrinogen

    Fibrinogen is important for clotting.

  • D. Albumin (correct)

    Correct: albumin provides major oncotic force.

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 Blood 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.
