Correct answer: E — Adrenaline 150 micrograms IM using 1 mg/mL solution

For anaphylaxis in a child aged 6 months to 6 years, the age-banded IM adrenaline dose is 150 micrograms using 1 mg/mL solution. Larger doses are used for older children and adults. Antihistamine and salbutamol may be adjuncts but do not treat shock. The pearl is to know age-banded adrenaline doses because delay is more dangerous than perfect weight calculation.
