Sample item

Which clinical pattern is typical of organophosphate poisoning?

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

The answer and the reasoning

C. Salivation, miosis, bronchorrhoea, and bradycardia

Organophosphates inhibit acetylcholinesterase, causing cholinergic excess with secretions, miosis, bronchospasm or bronchorrhoea, and bradycardia.

Option by option

  • A. Hyperthermia with rigid muscles after anaesthesia

    Anaesthetic hyperthermia suggests malignant hyperthermia.

  • B. Dry skin, mydriasis, and urinary retention

    Dry mydriasis suggests anticholinergic toxicity.

  • C. Salivation, miosis, bronchorrhoea, and bradycardia (correct)

    Correct: cholinergic excess explains this syndrome.

  • D. Jaundice with pale stools

    Jaundice has hepatobiliary causes.
