Box jellyfish sting — OSCE

Station brief (8–10 minutes)

A 5-year-old girl is brought to a north Queensland emergency department ten minutes after wading at a beach in the stinger season. She has severe immediate pain and angry whip-like, cross-hatched skin lesions across both legs, with tentacle fragments still adherent. She is becoming pale and drowsy, with a weak pulse and a blood pressure that has fallen to seventy over forty. You are the registrar leading the resuscitation, with a skilled nurse and a junior doctor present. Run the first aid, give the correct antivenom, and resuscitate while retrieval is arranged. Name the source for each threshold. ^{[9] [11]}
