Sample item

Which mechanism can produce peripheral oedema in a patient with heart failure?

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

The answer and the reasoning

B. Raised capillary hydrostatic pressure

Heart failure can raise venous and capillary hydrostatic pressure, driving fluid from the circulation into interstitial tissue and producing dependent oedema.

Option by option

  • A. Excess epidermal keratin production

    Keratin overproduction causes scaling disorders, not dependent swelling.

  • B. Raised capillary hydrostatic pressure (correct)

    Correct: higher capillary pressure promotes outward fluid filtration.

  • C. Increased erythrocyte production

    Erythrocyte production does not directly create interstitial fluid accumulation.

  • D. Loss of a single nerve root

    A nerve-root lesion produces neurological deficits, not systemic oedema.
