What is the maximum single dose of epinephrine during pediatric cardiac arrest?

• A. 0.1 mg
• B. 2 mg
• C. 1 mg
• D. 0.5 mg

Answer: (C)

In pediatric cardiac arrest, epinephrine is given at 0.01 mg/kg IV/IO every 3–5 minutes, using the 1:10,000 concentration (0.1 mg/mL). The dose is limited to a maximum of 1 mg per single administration. This means you tailor the dose to the child’s weight, but you never exceed 1 mg at any one time. Why this is the best answer: the weight-based rule (0.01 mg/kg) ensures appropriate autonomic stimulation across a wide range of pediatric sizes, while the 1 mg cap prevents overdosing from especially larger children. For example, a 10 kg child would receive 0.1 mg (1 mL of 1:10,000 solution), a 50 kg child would receive 0.5 mg, and a 100 kg child would reach the 1 mg maximum. Giving a dose like 2 mg would exceed safe per-dose limits for pediatrics regardless of weight, which is why that option isn’t used. If the child’s weight is such that the calculated dose would be less than 1 mg, you give that smaller amount; if the weight would push the dose to 1 mg or more, you administer 1 mg as the maximum single dose.
