Reveal the benchmark

Hidden so they don't bias your answer. Score yourself first, then reveal them to compare.

  • Single dose: 14 × 15 = 210mg. Max daily: 210 × 4 = 840mg.
  • Children's paracetamol is usually 120mg/5ml or 250mg/5ml - so the practical answer rounds to convenient measures.
  • Adult max is ~4g/day (around 50-65mg/kg depending on weight). Children dose by weight; adults dose by hepatic capacity.
