The adult epinephrine auto-injector delivers ___ mg of epinephrine, and the pediatric auto-injector delivers ___ mg.

• A. 0.15 mg for adults and 0.3 mg for pediatric
• B. 0.3 mg for adults and 0.15 mg for pediatric
• C. 0.5 mg for adults and 0.25 mg for pediatric
• D. 0.1 mg for adults and 0.05 mg for pediatric

Answer: (B)

Dosing of epinephrine auto-injectors is based on patient size and typical device formulations. For most adults, the standard single-dose auto-injector delivers 0.3 mg of epinephrine. For children, especially those around 15 to 30 kg, the standard pediatric auto-injector delivers 0.15 mg. This fixed-dose approach provides enough epinephrine to counteract life-threatening allergic reactions while avoiding excessive dosing in smaller patients.

So the pairing that matches common auto-injector formulations is 0.3 mg for adults and 0.15 mg for pediatric. Doses like 0.5 mg or 0.1 mg aren’t the standard pediatric/adult combinations used in typical EMS practice, and swapping the amounts would not reflect standard devices.
