Sample item

What does clubbing of the nails represent?

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

The answer and the reasoning

B. Bulbous enlargement of distal fingers with curved nails

Clubbing is enlargement of distal phalanges with increased nail curvature and can be associated with pulmonary, cardiac, gastrointestinal, or other systemic disease.

Option by option

  • A. A bruised nail after trauma

    Trauma causes localized subungual haemorrhage.

  • B. Bulbous enlargement of distal fingers with curved nails (correct)

    Correct: distal phalangeal enlargement defines clubbing.

  • C. A fungal infection limited to toenails

    Fungal infection causes dystrophic nail changes, not clubbing.

  • D. A superficial white scale on the nail

    Superficial scale does not create finger enlargement.
