Sample item

Which vomiting pattern in a young infant suggests hypertrophic pyloric stenosis?

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

The answer and the reasoning

B. Progressively forceful non-bilious vomiting after feeds

Hypertrophic pyloric stenosis causes progressive gastric-outlet obstruction, leading to forceful non-bilious post-feed vomiting, hunger after vomiting, dehydration, and a hypochloraemic metabolic alkalosis if untreated.

Option by option

  • A. Occasional nausea during car travel

    Motion-related nausea is not the typical progressive infant pattern.

  • B. Progressively forceful non-bilious vomiting after feeds (correct)

    Correct: forceful non-bilious post-feed vomiting is characteristic.

  • C. Bilious vomiting from the first feed only

    Bilious vomiting suggests obstruction distal to the ampulla and needs urgent evaluation.

  • D. Blood-streaked cough after exercise

    Blood-streaked cough is a respiratory symptom, not pyloric obstruction.
