What is the appropriate Epinephrine 1:2000 aqueous IM dose via EpiPen Junior?

• A. 0.15 mL
• B. 0.3 mL
• C. 0.05 mL
• D. 0.5 mL

Answer: (A)

Autoinjectors deliver a fixed dose, so you don’t adjust the amount based on weight in the moment. The EpiPen Junior is calibrated to give a pediatric dose in a single actuation, and with the 1:2000 aqueous formulation that fixed dose is 0.15 mL. That volume is the standard amount designed to provide the appropriate amount of epinephrine for a child in this setting, while minimizing the risk of overdosing. The other volumes do not match the device’s fixed-dose specification, so they would not align with how this junior autoinjector is intended to be used.
