Sample item

Which element of Virchow triad is illustrated by prolonged bed rest after surgery?

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

The answer and the reasoning

D. Venous stasis

Immobility slows venous blood flow, producing venous stasis that promotes thrombosis; this is one of Virchow triad along with endothelial injury and hypercoagulability.

Option by option

  • A. Thrombocytopenia

    Thrombocytopenia generally increases bleeding rather than causing venous stasis.

  • B. Endothelial injury from vasculitis

    Vasculitic endothelial injury is a different thrombosis mechanism.

  • C. Inherited protein synthesis failure

    Inherited protein abnormalities may cause hypercoagulability but are not created by bed rest.

  • D. Venous stasis (correct)

    Correct: prolonged immobility promotes venous stasis.
