Correct answer: B — IV or IM ceftriaxone or benzylpenicillin immediately and aggressive fluid resuscitation

A child with fever and non-blanching petechial/purpuric rash with signs of shock is treated as meningococcal septicaemia until proven otherwise. Immediate parenteral antibiotics (IV/IM ceftriaxone 50 mg/kg or benzylpenicillin) must not be delayed for investigations. Aggressive fluid resuscitation with 0.9% NaCl 20 mL/kg boluses is given. Lumbar puncture is deferred if the child is haemodynamically unstable.
