Correct answer: D — 120 micrograms IV/IO

Explanation lettering: E = shown as A · D = shown as B · A = shown as C · C = shown as D · B = shown as E

The paediatric arrest dose of adrenaline is 10 micrograms/kg, so a 12 kg child receives 120 micrograms (1.2 mL of 1:10,000). The adult dose of 1 mg (A) is a ten-fold overdose, and the intramuscular anaphylaxis dose (D) is the wrong route and indication. Weight-based dosing prevents dangerous decimal-point errors in paediatric resuscitation.
